Plumber here: just used a time start delay you described as a temporary fix for a broken control panel for a lift station. Used a single float from the pitt, to one of the contactors, and the float to the time delay. Works great and the pump is not short cycling.
You're an excellent teacher. Lots of other channels make the same topic seem soooo complicated and hard to grasp. I wish I had you to teach all my classes... then I'd have all the Aces in the deck 💯👍
very useful gadget for any application, on my main switch i added a system with contactors and time delays on make and break, so any time there is power outage these time delays prevent the inrush when there is no one at home. after the set time on make then the contactors drop and the other energizes, in this way when the city power goes and come your appliances is protected from inrush voltage. Thanks for the lesson on the use of time delay.
Nice tutorial and very detailed! You are very gifted in communication skills. You should be teaching at a Tech college making lots of money Jumper Man.
Hey Jumper man Tech, I am not a HVAC tech person, just a regular guy with a question about what kind of timer I need. My situation is as follows, I have a zoned HVAC system (at least that is what I call it), I have a 3.5 ton Lenox heat pump that supplies most of the living space in my house and then a separate 2.5 ton Lenox heat pump that supplies the 4 bedrooms. I am 74 and me and the wife are retired and to save money we only run one system at a time. Mostly during the day when run the 3.5 ton unit, and then at night when sleeping we run the 2.5 ton system. Sometimes we need to run both systems, but not at the same time, we run one system for an hour, then turn it off and run the other system for an hour and keep cycling this process which tends to make the whole house comfortable without running both units at the same time (which uses lots of electricity) So, I am in search for one central timing device (timer) that I can set to turn ON one HVAC system for an hour (or whatever time I like) while the other system is OFF, and then after an hour, it would switch units turning one OFF and the other system ON (from ONE timer). I know I will have to add a relay to each unit to take the START/STOP signal from the timer and then in turn that would cycle the HVAC systems one ON and the other OFF and then after an hour the time r would reverse the systems. What kind of time do I need? Thanks
These mods are nonstandard & most tech will not do it. Too much can go wrong, he gets called back or worse, unintended consequences that makes him liable. But...diy...there are flip-flop or cyclic NO/NC timer relays ( e.g. Siemens) that can be adjustable. You can put it on the tstat so only one compressor is on while cycling.
Simplest option is to just have each unit connected to different t-stats that have a scheduling feature. Doesn't matter if both run at the same time. It's the overall time period they run for that matters. By optimizing the schedules you'll get your optimal energy efficiency.
Yes, this helps, I have a Essex 133 make delay, I'm trying to test if they are good for a staged electric furnace control. My mystery was how the circuit was completed. In your diagram, it seems like the contactor coil is the circuit completion. Can you give some idea of how much resistance is in a contractor coil? Or can it be zero. Then I can see if I can make a test rig on the bench. I look forward to your opinion. Tx
Your videos are great, thank you for taking the time to make this content! Where would this DOM typically be installed? At the air handler or outside at the condenser? I have two units and one t-stat, would like to delay one to minimize voltage drops when they both kick on at once. Thanks in advance!
Hey, Jumper man: Great video. Thank you! I am trying to find a way to briefly delay the start of my small irrigation pump so that there will be time for the water valve to open first (better for the system over all). The sprinkler controller provides 24 volts AC to activate a 110V pump relay. If I install this unit that you are showing 'inline' on one of those 24 volt AC wires will that work to give me a programmable delay to the pump relay? Thanks for any confirmation you can provide and keep up the great work.
Hello there, we have problems with Voltage fluctuations, where the voltage dips briefly and then comes back on right away. This causes my AC compressor many problems, so I installed a ICM Delay on Make Timer. The strange thing is that the timer does not cut out at those dips but only delays once the electricity goes off completely ( same counts for the built in delay in my Air handler thermostat. So here my question : would a Ditek Surge Protector be a solution or do I need to install something else ? Thank you so much !
Yes Luis, this can be installed on any refrigeration system but, in case of a freezer, the wiring scheme is different because usually there is not a 24 VAC control circuit in those devices. So you need to insert the delay time relay in the 120/230 volt circuit. In order to do that you need to cut the white wire loop on the relay. I suggest finding help from someone with knowledge on electricity in order to avoid injury to you or your equipment.
Hi. I had my HVAC tech install one of these on my unit and worked for about a year but then the compressor would stop running even when there was nothing causing a short cycle. The tech came out and checked the cap which was good, then checked the contactor and contacts were burned/worn. He thinks the delay on make timer may have caused the contactor to chatter resulting in contact burn and short cycling of the compressor. That said he replaced the contactor but also removed the timer. Have you heard of this happening with theses timers? Should I purchase and install a new one?
Adding to my comment above. Reading some other message boards it looks like some of these timers are causing a voltage drop on the load side which cause contactor chatter. I ordered the one in your link but I’m wondering if I should install it or not.

This is the best explanation of an A/C circuit I've seen. Great video.
Thank you! Stay tuned for new videos every week🔧⚡️
Again another Great learning video. 👍
Blessings, and Thanks so much for sharing 🙏.

Good tutorial. Interesting subject. As always good job. Be safe. ⭐️⭐️⭐️⭐️⭐️

Need this in Florida !
Wow! It's so clear and easy to follow, thanks.
You're very welcome & thank you! Stay tuned for new videos every week🔧⚡️
Very helpful and especially the diagram while you were explaining 👌
Waow didnt know those things were so cake to install. Never had to install one but now I know ez.
Great video Jumper man!
Thank you! Stay tuned for new videos every week🔧⚡️
You are the future thank you so much jumper man tech
time to shine!🌟
Thats right! Stay tuned for new videos every week🔧⚡️
Do you have any videos on three-phase delayed timers on a compressor for a void 6000 machine

This is excellent. Can you create a similar guide for a two thermostat one compressor system?

If wanting more delay time, can you wire two of them in series?

Glad to hear that! Stay tuned for new videos every week🔧⚡️
For US region and for homes, do we need to cut the wire for 120-240V ?
Greatest vedio well done
Thanks
You're very welcome & thank you!
When the delay on make timer times out, and the contact closes, what is the expected voltage drop across the terminals at 208 volt operation?
Any idea what the specific increments are between .03-5min? 5-10 is self explanatory, but looking for specific line to time for .03 - 5min.
Thanks
This is very helpful, can we use the same circuit for Delay On Break Timer as well. Intercepting the wire from T-Stat Y and the contactor ?
How does this timer work without a ground?
EXELLENTE
Sir please one video make on ICM-220 lock out relay Waring cannection.
Im installing a generator, I’m load shedding my 2 ac units and going to use these so both ac wont turn on at the same time when power is out.

There’s one Made in China Knockoff, make sure you don’t buy that one. This one clearly says Made in USA.

Thats a good thing! Thanks for watching & Stay tuned for new videos every week🔧⚡️
THAT'S A DELAY ON "BREAK" set-up.. NOT DELAY ON "MAKE" .. You fucked up bro.. not calling you for service either.. kidding...
