1000 ohms per volt. 460 volt compressor should be at least 460,000 ohms
Just a general question. Does Colder ambient temperatures increase or decrease your subcooling?
Will subcooling decrease or increase on cooler days on an air cooled A/C unit with a TXV.
I have some MR88R controllers available.
Over 20 used and good working condition MR88R control boards $200 each plus shipping.
2001 date. All in good working condition. Make an offer.
Are you still looking for MR88R controllers?
Madonna? I thought that was Betty White performing at the half time show.
?????? You lost me Max.
Its Multistack with 10 modules, load is very stable (shut off other modules to keep load up)tandem scroll compressors, txvs are stable within a degree once subcool gets up around 7, two condenser...
LMAO Maxter! I feel so dumb. If subcooling is higher at lower ambient, then why do I see more sight glasses bubbling in colder temps. In order to have subcooling does't it have to be a solid column...
Only with persistence and patience.
water is expanding when heated, with no expansion tank the water pressure will increase until the releif valves blow. Or pressure regulator could be bad.
Saftey glasses and good gloves!
What is the proper way to determine the correct subcooling for an air cooled chiller when you have low ambient conditions? Is there a chart or formula where you can enter temps to determine what your...
A whole bag of Robins Eggs!
My guess is the internal pressure relief in the compressor is weak and opening up prematurely.
Thanks guys. TAC mine is older than the info you posted. The unit I am working on is a recip. compressor. The defrost circuit board has two sensors theat come off the bottom of the board, one with...
Can anyone tell me where I can find a diagram online for a Lennox M# CPH10-653-1Y?
I can not read the serial # on the tag.
I am looking for 3 humidifiers to install in a 7500sq ft apartment with 14 ft ceilings. These are going on two 4 ton and one 5 ton HPs. Need to have a wireless humidity sensor since I can not get...
Less likely to hold water or debris if mounted upside down.
Thank you Joker.
Can anyone break down this model number? It is on a A coil for a mobile home unit. I am guessing 48,000 btu's, but what do the other numbers signify.
Yep that sounds right.
Is there a way I can use two remote indoor sensors and average them or do I have to do four indoor sensors?
