I WAS ABLE TO PROPERLY CALIBRATE THE LEAVING WATER TEMP SENSOR. I FORGET TO MENTION THAT I ALSO HAD TO MODIFY THE START-UP DELTA TO GET THE CHILLER TO START UP.
@EverythingHVACR 😄😄😄😄😄.....sure seems to be the case. I'm not entirely sure what type of sensor it is. I can assume it's a standard 10k type 2 or 3. I could be way off though. It would be the first one I would replace. I've been able to get away with offsets so far. I would like to think its a standard kind of thermistor.
@NewDestinationEng compressors aren't ran like a traditional motor, say like a blower. Most variable speed compressors are running above 60hz. I know the York ones run at 200hz at full speed. Hyper heat mini split one get up to 300hz. It was designed to take the speed above utility power. You can overclock a blower on a VFD as well if you wanted to, it wasn't designed to do so per say...but its possible. It's about a larger capacity control which is used for load matching. I rarely see them running at full speed. Even in the dead of summer it isn't uncommon to see one running at 40,50,60hz.
Badass! Let me ask you a dum question, how far do you need the water temp thermometers in Pete’s plugs to get an accurate water temp? I’ve had problems for years getting some to in all the way or even at all sometimes, I realized recently it looks like, sometimes with then halfway or so In the Pete’s plug the temp reading is just as accurate.
@@BleedingEdgeHVACR only far enough to get into the flow. Some of those Pete's plug adapter are like 3'-4" tall, some are shorter. The piercing tip should be small in diameter if it's kinda rounded it'll be a pain. I have adapters that I use my Testo gen 1's to check PSID.
@@jasonjohnsonHVAC oh what, do you mean your adaptors are like 1/4” sae to the narrow needle style that the Pete’s plug thermometers are? So they fit in those ports?
@BleedingEdgeHVACR sure is. Most the guys i work with use their Testo's as well. Better than carrying around analog gauges and they can be zeroed every time. I have a video or 2 with me using them

Good work around, keep em coming 👍
🤜🤛🫡
Good vid ... Those compressors are huge ... Thx
@@Eddy63 they are single screw with 2 gate rotors. The end is the oil separator. I like them. They are extremely heavy though
Those compressors sound crazy winding down. Good video JJ.
@@fshn76 they are big ones. 200 tons each.
Good stuff, Jason! Why can we not get better sensors? Seems like everyone has trouble. What type of sensors are they?

That's strait up a meat thermometer 😂
I'm gonna have to try one on a petes plug now. Nice video.
@@josiahpierson3636 sure is. Cheap and it works
@@jasonjohnsonHVAC heck yes, glad you showed that in the video. Nice tip 👌
Nice little work around to get it running, half the time that's what our job is lol. Just get it running!
@@ZRock7771 got to do what we got to do.if there is a way work can continue safely....let's rock.
That thermometer seems to fit properly. Do you know the brand or is it a standard chinesium special?
@@sterlingarcher46 Amazon-esium. Lol....its a cheap meat thermometer that works good
Nice vídeo. Do you have any clue why the compressors work on 80hz instead of 50hz or 60hz? That got me thinking

@@jasonjohnsonHVAC thanks! Haven't work on screws and on centrifugals yet. I mostly deal with scrolls

Do you test your steak with that thermometer as well on lunch break?😂😂
@nickc6399 absolutely....water treatment chemicals and a porterhouse....hell of a good combo
Does that unit have a z curve sensor?
No it does not. These are just standard 10k type 2 thermistors
