I will have a Bosch heat pump installed in a few days and need to adjust 5 ton to 4 ton. Thank you so much for the information, great video!
Well done brother!
Great video definitely will help with the summer setup. I know people have asked but could you show us the heat settings. I'm sure with this winter blast we all could use the proper setup.
Thanks for the video… ran into one of these machines for the first time today… wouldn’t you know… a humidity control issue… i am grateful that you have taken the time to share the info you have learned that is not available in the manuals.
Great video! Wish everyone put some much care and thought into an install.
@@Richie_7777 thanks
Great video! The ecobee is a powerful stat. It's awesome how much backdoor control they give you. I had never thought about how reverse staging could cause ideal dehumidification removal for these units, that super smart and simple.

Over in Wake Forest, NC, myself. Currently trying to figure out how to get a couple of similar Bosch systems at my house to properly dehumidify and this helped big time! Cheers!
@@hansu327 youre welcome
Great video! I had a Bosch IDS 2.0BOVB-60HDN 5 Ton Condenser, paired with a Bosch BMAC4860DNTF 5 Ton Coil, and Bosch BGH96M120D5B Gas Furnace (Propane). It was installed 6 months ago, and it seems that the company that sold it to me doesn't really understand it enough to tweak it for maxium efficiency. The heat pump is an energy hog, but I plan to address that in the spring here in the NY/NJ area. Right now, the temps dropped to 0 degrees last night, and my Honeywell T10 thermostat was set for 70 degrees. At 3 am I woke up cold, and saw that the temperature on the thermostat was 66 degrees, but it still was ON, heating to 70. I went to the furnace and watched the flames for 15 minutes and they stayed lit. After the sun came up at 7 am, it took another 4-5 hours before it got to 70 degrees, and it's stayed that way all day, fine. I had a secondary contractor come in last week and pop the cover off and he said this two-stage unit was only operating as a one stage as there were NO wires where they should be. And after the load calculation he did with a 3D app, my 3,000 sq foot house should have the unit sized for 4 ton instead of 5 ton. I then had another contractor talk to me on the phone saying, "No, the two-stage feature is a switch on the board." And he also stated that I need the 5 ton for my sq footage. Any ideas? I'm lost. Am I missing wires for the two-stage operation or are the settings on the board? Thanks.
Hi Jerry, to answer that question, I'd need some more information and it would take some time. I offer consulting services at $200/ hour. I could probably get to the bottom of it remotely from a Zoom call for an hour or 2. If you'd like to pursue that further, go to my website www.comfortsciencesolutions.com and fill out a request form. Thanks!
@@timdestasiohvac Thanks. Followed you on your other pages and will set something up with you.
Hi, thanks for your videos, and also for taking the time to answer questions.
Are you going to make a video about settings for heating run times?
@@alfort1943 sure. I get about 5 weeks of cold weather here though
My Rheem system had a similar problem, and I did the same thing, lowering the fan speed, except I don't believe I have dips switch on my outside unit. The best thing here is i have the same thermostat, and your breakdown of the suggested setting is amazing.
@@Litt1leMe thanks! Slowing the blower works with non inverter systems too!
Any issues with slower blower motor speeds during the winter months when AUX heat is called? BTW, great video. thanks!
@zee_928 not in my climate. I rarely go into 2nd stage in heating and never aux. Im making a heating video soon.
@@timdestasiohvac I am 2hrs west of you, Raleigh. my issue is my 5 ton package unit is doing a defrost cycle every 20 mins when we were in the 20s last week. No heat strips, so during defrost I get AC cold air. My split system for the 2nd floor is identical to yours.
@zee_928 you need strips. And there might be a charge issue too
Really awesome video! Could you please do something like this for dual fuel (gas/heat pump) settings?
Great job. I appreciate this vid
We love the Bosch, Philly has humidity but nothing like the Southern areas. The IDS lite is a great entry level product. We've had customers floor by the difference in sound level outside and electric cost to run the unit, coupled with comfort of a continuous flow of heated and cool airflow. The 20 seer high heat model in a cold climate cannot be beat. Previously we used Daikin or Fujitsu compact cassette blower mini split ducted units, which can work with existing duct system in some cases. Unless the existing duct system is a complete mess, Bosch will work. However, the use of Aero Seal process might be required.
@@dennistreacy3595 great comment!
Excellent information and presentation. Have been installing the A and B series for only the last 2 years in Northern California and set them only in AC mode only. Stilling learning through trial and error but I do agree with all your points. Keep us updated with new videos on future Bosch issues or repairs you encounter.
@@TheRealoldcar thank you

Agreed please!!
I got the first generation Bosch. Has been amazing. Will I get more benefits out of the Ecobee than Bosch BC-100 I don’t have a 2 stage air handler
Great info! Can you run the Bosch IDS with a variable speed blower?
@@pat750 yes!
thanks for your video. Can you share more info about your monitoring setup? I currently have sensorpush sensors at the start and end of the return duct and at the start and end of supply (to measure split).
I struggled for a long time with humidity issues from my unit. The thing that had the greatest impact for me was shimming the unit so it leaned slightly towards the drain. When I stuck a bore camera in the unit I noticed a significant amount of water sitting below the coil and the primary drain not being utilized. The unit is in a horizontal config.
@@adambrock look at my video feed youll see some content on it
Tim, if my variable compressor operates like yours and it hooks up via the y1 only, can i still run my ecobee to my variable blower via y1 and y2?
Great video, can u show ecobee setting for heat mod ?
@@dmytrokhomchyk2290 sure when ut gets coldet
Cold is here :))
I basically have the same setup. What settings would you recommend for running heat on the ecobee? I seem to run into a problem where my heat pump is blowing lukewarm air and runs all night.
I’ve heard a larger coil increases surface area, which increases efficiency but makes it harder for the coil to get to a lower temperature, decreasing latent capacity.
But for a system like the bosch ids that maintains a constant evaporator coil temperature(and set to lower), I figure itd be different
@@ElectroTree01 it increases latent and sensible
@@timdestasiohvac With an inverter system and the desired coil temp set to lower temp, I suppose that is correct. I guess the comment didn't update properly after editing, so sorry for the lack of clarity.
Great information man, i was wondering if there was a way to lower the fan speed the closer it gets to the setpoint and the reverse staging is perfect for that. I wonder if Nest thermostats have that same feature. Most of my customers love either the nest or ecobee
@@otisgregory5939 youd have to retrofit the blower controls for that.
Ecobee > Nest
@@timdestasiohvac I agree , but some homeowners love them things like it was their kid or something. Right on for the information 👌
@timdestasiohvac on the heating side of things, up here in Indiana we get around 10-15 degrees in February, sometimes below 0 does the reverse staging effect the heat side as well, can you say have a 15kw and it'll only run on element when it's more than 1.5 degree then kick on both if it's more then 2 degree difference.
@@otisgregory5939 in Indiana your heating load is considerably higher than your cooling load I assume. In this case you need a cold climate heat pump or dual fuel if using a traditional heat pump. Sounds like you have a traditional hp with electric heat. In this case you're going to be running a lot of electric strip heat which isn't ideal. You can reduce how much strip heat by speeding up your fan in heating season, then lowering it using the dip switches for cooling season.
Great video... thanks so much.
I'm just north of Toronto, ON (CAN) and have the 3ton model with a 2-ton coil but with the Ecobee 3 lite. I have my Bosch running with only a Y1 (though I'm thinking of hooking up the Y2) and it ran perfectly during the summer months. I have my cool differential set a 1F (0.6C) and have ZERO setback, and it maintained a 75f (24C) with zero effort. I did have to lower the air handler fan speed though to increase more dehumidification.
Now it's winter in heating mode but I'm finding the compressor fan to be running at a high speed even though the temperature outside is about 37f (3C), and is much louder than in cooling mode.. I wondering if I hook up the Y2 wire to enable the Stage 2 setting and allowing the air handler fan to run at a higher CFM, if this would change how the compressor fan operates? Would the compressor fan increase even more or decrease as a result?
It will be louder in heating mode. The outdoor fan will run at high speed to absorb as much heat into the outdoor coil as possible. The compressor will also periodically speed up as part of an oil return mode if it runs in 1st stage for a long time. Since you're in a colder environment you definitely need to hook up Y2 with reverse staging in heating and cooling as I show in the video.
@@timdestasiohvac thank you so much for your kind response. I'm going to hook up the Y2 wire for 2nd stage cooling/heating but I will likely not require it. Cooling went fine without the need of 2nd stage during the summer (1st stage ran for 1hr no problem to maintain 1F differential). As for heating, so far at 4C (40F), it has been able to maintain the 1F, and because we have low cost natural gas, my furnace will likely switch over at -1.1C (30F) due to the economic crossover. I was just more wondering about the noise level and if a 2nd stage would be louder.
@@chimaican01 I rarely go into 2nd stage in cooling and DEFINITELY don't need it in heating but I am on the NC coast lol. You have the opposite problem. Hook it up and see what it does.
@@timdestasiohvachi Tim its me again how can I run my stage one longer, my stage one runs only for 10 minutes then starts the stage 2. How can I set the fan speed?
@@5sunny01 seperate your stage 2 by 2 degrees from setpoint. Not sure I can help you without booking a consultation.
Tim: Thank you again. Will monitor this overnight as I made my cooling related settings match yours, wth the exception of a 15 minute run time minimum in cooling. I added 5 minutes of overcool time. Because we don't have a whole house dehumidifer like you do, and it being not too warm in late Sept, humidity is up, but demand to lower overall temps is down. Do you have a similar video for this Bosch system (or recommendation for someone else) but for the heating side of the equation for Ecobee? I've got this HP20, but I also have a gas furnace for aux heat. I want the HP to do it's thing and keep us warm, but operate efficiently to the extent practical in the winter,. It will cut out below 35 degrees. Tall ceilings, 120 year old house, decently insulated, but its' only going to become but so efficient. Any direction you can provide on that would be appreciated.
Thanks for the video, great info. My wife and I just finished building our house this year and went with the Bosch 18 seer units. We have a 5 ton outdoor unit paired with a 4 ton indoor air handler and a 3 ton outdoor unit paired with a 3 ton air handler. I see you talk alot about setting the units up to properly dehumidify in the video, but you don’t mention anything about cost savings on the monthly electric bill. I assume the way you set up your unit would also be the best way for energy usage cost savings on the monthly electric bill? My units will typically run for about 20 minutes and then will shut off, and the airflow that comes out of the registers to cool my house is pretty strong. And mine only are set up for 1 stage of cooling. With these inverter units, I can’t help but think that if the units ran longer at a lower compressor speed and/or a lower fan speed, then I would see greater savings on my monthly electric bill, and would also achieve better dehumidification like you mention. So I’ve just been trying to figure out if my units are setup properly and if I’m getting the maximum energy savings I should be getting out of these units, but I’m not really sure how to determine that.
First, thannks. Second, you SHOULD be following the steps in this video including 2 stage cooling. Your thermostat should have a Y1 and a Y2 wire. Second, if you're still cycling off on a really hot day, you should slow the blower speed down.
I am happy with my bills, but that is the last thing I am worried about in home performance. My priorities are safety, health, comfort THEN efficiency.
Okay thanks. What about when winter comes? Will slowing the blower speed or adjusting the dip switches as you showed in your video have any negative affects in winter? Or those settings are also good for winter?
@@Jake-fh1yw thats DEFINJTELY a concern but not for me. Im on the NC coast and my unit never went into 2nd stge heat or defrost last winter lol
@@timdestasiohvac. You’re not answering his question. Maybe you’re not concerned about your electric bill. But a lot of people are. Does running the unit by your way increase (and by how much) the cost of his electric bill. Thanks
@@chessiekid4018dont be rude. Set your heat pump up so it can maintain heating conditions with minimal strip heat. If that means running a slightly higher fan speed so be it.
I just had a Bosch unit installed at my house and have an ecobee. Do you have any set up ideas if I only have the BVA15 handler (the non two stage handler unit). I assume this means I can't change my heat pump to two stage on the ecobee? I ask because some of the settings on the ecobee are not the same or don't show up. I assume since I have a single stage handler.
I'll also add my humidity runs a bit higher than I'd like. Around 65-67 adjusted and verified by a trusted meter
@@ryanp143_ a 2 stage blower is critical to my approach because you set the capacity, therefore the run time, by airflow.
@@timdestasiohvac I appreciate the quick reply!I assumed that would be your answer but if I would have known I wasn't getting a 2 stage blower with what was ordered I would have made the change to have it include the 2 stage but unfortunately I don't believe I can change it now. Do you have any settings that could potentially help with the single stage?
@ryanp143_ there is a way to wire a n.o., n.c. relay to use high and low stages. Then use Y2 on the thermostat. I can draw one up for you but that's a paid consulting service for my $200 minimum. If youre interested visit my website and put in a cobtact request www.comfortsciencesolutions.com
@ ok! Again I appreciate the quick reply, I've had this installed for around 2 weeks so I may have to do that consult. I'll give it another week or so and see where I'm at. Thanks again!
Hey Tim, great info here! question for you though, with a home in need of 3 tons of cooling, would you recommend 3 ton condenser and ahu or upsize them then derate with j2 dipswitch?
@@MikeJohnson-bz1rp i'd go with a 4 ton AHU, 3 ton outdoor and run it at the slowest fan speed possible to maintain temperature in summer.
@@timdestasiohvachow do you set it to run longer on slow speed I have ecobee premium T installed
Great video. I guess it doesn’t matter the evap coil is bigger with a variable speed compressor because it can control the saturation temp. With a single stage compressor a larger evap coil isn’t good for latent capacity because the larger coil gives it a larger temp/pressure? Is this correct?
@@sirfishalot6992 no the larger coil improves latent and adds seer
Hi Tim-great video....have you ever worked with fan handler products? check them out....i am using their heat pump controller on my bosch heat pump in upstate ny with good results
@@bobrumpf2576 what do you like about them?
My installer wired W2 and theres no Y2 wire. Should i be concerned? Everything works.
My Bosch system was stepped up to the next larger size indoor unit. Even after setting the fan speed to the lowest setting, the air noise from the floor registers is considerably louder. I also think the indoor unit is too large for the size of the ductwork. While the system is running, if I angle out a filter from the ductwork a few inches and let go, the filter snaps back into the duct. Like the return side is straining for more air. Not scientific, but my previous system never did that or made as much air niose. Be careful if you want to step up the size of your system.
@@steadyeddie7453 looks like that was a poor design. Your ductwork is grossly undersized. I never said to do that now.
@@timdestasiohvac It appears you did it the correct way and considered all the factors when sizing up the system. When the weather warm here in MD I will take a look at the DIP switch settings on my outdoor unit to see if they were configured for best efficiency. I tend to think they were left at the factory. Thanks for the video.
Tweeking my newly installed Bosch 20 and my Ecobee Premium Tstat. My installer came back last night, and made adjustments to the air handler and outdoor unit to help maximize dehumidification similar to what Tim demonsrated. At present it is not particularly hot outside, but humid. The unit doesn't run as often right now in general because of the moderate temps I paid attention this morning to activity from overnight. Although I can't post an image, the Ecobee graph shows that it cycled throughout the night, but seemingly started every cycle in stage two and then eventually reverse cycled back down to 1st stage. Shouldn't my unit (unless there is a significant difference in desired temp and setting) start in stage 1, run for a period (presumably longer) and then decide if stage 2 is necessary?
@@andrewsugg6844 yes you may have some overlap on the settings. Take another look at the ecobee
@@timdestasiohvac Thank you Tim. I will. I've got a call into Ecobee right now. They are to call me back. Ecobee can see my setup remotely and determine if something is mismatched as you suggest. I'll let you know what they recommend.
Hi Tim, so I got the wiring diagram from Bosch then connected all the wires and followed your settings, the ecobee premium couldn’t detect the y2 and w2 wires, then I manually added the wires.
Then powered up the system and started the cooling. Temp was 75 and Tstat temp was set to 73, system started in again C2 (stage). What am I doing wrong. I thought it supppse to start in low stage then ramp up to c2 ? Is that right?
Yes, it should ramp up and ramp down. I'm not sure I can helpe you diagnose what's wrong remotely. I'm sorry you're having trouble.
Hello brother. I have a problem with a 5-ton Bosch heat pump. The equipment was installed by another person, the card of the external unit shows the code P2 and then the H5. Now it is giving the code P3.

Tim i have a bosch. I need some tips with the HP. And balance point explained. The hp will run below balance point and sometimes itll run say point is 35 itll run at 28 then next cycle is fossil. Is this common?
@@Keith_Mikell if its the Bosch thermostat it may be looking at other factors. I dont know as much about that control.
I know there is a lot of variables but I just had a 3 ton Bosch ids 2.0 condenser and a/h installed in my home. I live in a couple miles from the coast in SC and the a/h in an unconditioned attic space. I know high humidity and dew point will affect if the a/h sweats but it seems mine is sweating a lot, including some condensation on the internal electrical. My old unit was a single stage 3.5 ton and my set up with a 2 zone with a bypass damper. Every basic thing has been checked, drain line, bypass damper, supply and return boxes for holes, but it’s still sweating. The fan speed is in the default position, would moving it to the higher position help with the unit condensation build up? And would that mess up the indoor humidity control?
You have a humidity problem in the space where the air handler sits. If it is an unconditioned attic, you need more attic ventilation in there to avoid air stagnation. I have to fix your problem with a Walmart box fan but that's the cheapest solution. The next cheapest solution is to encapsulate the attic properly with spray foam.
Just had a 20 Seer Bosch heat pump with dual fuel propane furnace back up installed. House cools great - but seems to run 5-6 minutes then shuts off. Humidity is in the low 60% most of the time. We live in DE so roughly same climate as NC.

Hi, quick question, does the air handler need to be installed in a controlled environment? My Bosch air handler is in the garage and is ‘sweating’ a lot, the installer said that is due to the garage is not a controlled environment. Any thoughts about it.
Thanks
@@alfort1943 he is correct. Especially if you live in a humid climate, the garage has a very high dew point and the air handler only has a thin amount of insulation on it. The only solution for you is to lower the dew point in the garage by keeping the door closed, sealing up any additional gaps and putting a dehumidifier in there.
@@timdestasiohvac

Hi, according to the Ecobee website, an interface module/adapter is needed for its thermostats to control a variable speed, or an inverter, system. Did you install an adapter for the unit in this video?
