    Looks like you need a crank case heater. I've seen that on a WMC when doing igv motor. I believe that there's a plug underneath the insulation on the cavity for oil drain too. I had DTC tell me that...

    York YT Codepak PRV hunting

    I came up on the chiller today set to 41.5°.
    Its modulating from 43-40. Prv is opening and closing. The pulse of the PRV is around 5-7 seconds which seems long to me. Is there a way to slow it down....

    It's odd to have low discharge superheat and not low suction superheat. Chev is right, verify the sensors but also make sure that your vapor injection is not flooding either. The economizer shouldn't...

    65% for 10 minutes. It does it long after the 10 minutes is over. The pressures and temps mirror the other chiller. Log sheets look good.
