Having issue getting ultra temp to control with Pentair home app. I have Com wire connected to Ultra temp and to intellienter with the ultra temp set to Rs485 mode. Any help appreciated.
Ok I will try, that, manual referenced ability to use J8.You have the Ultratemp connected to J8 the IS4 Remote block.
It needs to be connected to J4 or J5.
You can put two wires under one screw and add it to either RS-485 COM PORT.

I connected to the J5. Error gone. But unit will not stop running.I don't see any wires connected to the circled connector.
Show me actual pictures of the UltarTemp control panel when it is doing what you describe.

Both intellicenter and ultra temp are set to channel 2 .
I reset the controller. Now the ultra temp will turn on when I drop the temp below current temp. If I turn it above it, how long should it take to turn back off?
Seems as the compressor does shut off, but the fan continues to run(overnight) never stops.Okay, it sounds like it is working.
There is a minimum cycle time on a heat pump. The compressor does not like quick on/off cycles.
Be patient and let it do its thing automatically and see if it is operating properly over time.

Does the fan cycle on and off when the HP is run standalone without RS-485 control?New replacement
