Document it and call the local utility. The problem with some of these great contracts that come through the doors and no offense meant. But you're price was probably cheap and likely the reason for...

Transformer is before the fuse so I highly doubt that the transformer has anything to do with your problem. Look for rubbed wires, run it in every mode/stage while monitoring amperage on fuse. Been...

The fins get real shinny when they are flattened. Shinny = clean right?

Acceptable Circuit Protection maybe, just a guess.

I see an issue trying to calculate VFD speed output by monitor timing of the increase or decrease commands outside of the controller that is actually controlling the timing. Will the JACE be capable...

Have used the same one for about 12 years now

Ivu tech tools is for the OPN controllers and Comfortview or Network Service Tool is for the CCN controllers.

I have been in the field for many years, far from a hack and have brazed small diameter joints and quick repairs without nitrogen for years. I never recall a call back from a blockage or issues due...

Had issues with multiple units on a roof doing the same thing. Had Carrier rep look at it and their answer was tighten the belts more than what we presently had. It solved the issue, but who knows...

I have had roofers completely seal condenser access doors, meanwhile there are two 24 inch fan shrouds on top. Yeah no water will get in there.

That must have smelled nice.

Correction, someone needs a beating.:grin2:

Muriatic acid

Hot gas bypass requires the compressor to constantly compress, with a digital scroll it does not pump when unloaded.

I meant number not address 20.

Everything I have looked at and tried comes back with the same conclusion that any DX9100 programmable module constant over address 20 can not be added.

What type of reheat, HW or electric? I wouldnt fail to cool if you have HW reheat.

Model number of the thermostat will help.
If you have a fan and or electric heat it would be controlled by PE switches using the normally open contacts and the thermostat would be reverse acting,...

Manual
Page 11 is the default settings. You will need to set each one manually back to default.

Great job. Grammy award winner for sure.:cheers:

Its probably an Altivar 66 drive but I cant find any literature for TCD600A only 600B which is newer. You can find the drive manual with google

I have not seen that board so I can not comment on how it will operate. We have a replacement job that the BMS is tstat type control to RTUs and customer does not want to upgrade so when I asked York...

Unplug it. Is it VAV or CV?
