We have a DMS502B71. We are making some progress.

There is no iTouch controller. And you are correct that he does not have experience with Daikin.

Need some help guys. Have a job with three Daikin VRF systems. I am with the mechanical contractor and will be working with our controls contractor tomorrow to try and resolve an issue. The issue...

I wouldn't worry about the drier.

We have installed lots of chilled beams. They along with radiant panels are a waste of money.

I would let your boss know that you are unhappy with his choice to put green rookie into service ahead of you. Then quietly start looking for another job.

Does the boss know you want to transition into service?

A great old timer once showed me how to "burp" and evaporator to remove oil. Maybe it would would on a compressor?

I'd like that info also. Let us know.

City Multi with a heat exchanger.

I doubt you will be able to ever determine the cause of failure. I had the same issue with an ACH550 last summer. Power in and no power out. No LED lights.

You may have a bad drive.

Once last winter for me.

I'd guess Nordyne also.

Pull the gas out. See if it's close to nameplate.

How do you zero the gauges?

thanks for the update.

I had similiar problem 2 weeks ago. I ordered a new powerhead and valve. When the parts came in, the Boss sent out another Tech. I don't know how it turned out.

Thanks Rundawg.

I'm looking for service bulletin HCOM-SB-11A.
Thanks

Have some electrical tape on hand.

You are correct. Mine has never left the van.
