I ran across this York chiller unit, with a remote condenser unit model h2ca360a25d. can you show me how to trouble shoot it..

[@jasonjohnsonHVAC]

I use a decade box to test specific modes. Use jumpers if you want to cycle each mode

Link to decade box, please.

[@LeoS41280]

Clearly it is a heat pump. You can see the reversing valve at 3:38.

[@shane3000]

@@LeoS41280 I agree , he said in the video at 5:45 mark that it was not

Is called RTOM "Relia tel Option Module". RTOM gets power and communicates with RTRM. Condensate Overflow switch, clogged filter switch, fan failure switch, factory smoke detector are some of the optional features of RTOM

Hi Eric, I had issues with 35 t Trane a/c unit. Unit was shot cycling about 2min run before lock out.(cuts off at 650psi) Condenser coil was cleaned and dryer filter been checked. I have not looked at the expention valve. Unit was only short cycling on first stage but it was working ok on second stage (high pressure was about 300-325 psi +30 C outside.. I would appreciate for any help. Thank you. Serge Alarm code was "comp 1 disable input / HPC " . Could please give me some advice where should be a problem. .

[@AGON17]

That alarm is for high pressure cutout the pressure switch is doing its job. Is this a heat pump? Is there a txv in the condenser area?
