Question about Heating & Cooling
I have read all the forums, got the full manual, checked the installer mode is correct but still nothing. Its 18C in the room but the DT92E thinks it is 28C and even with the temperature set at 35C it does not switch on the heating. ECO is off, setting are correct. It has lost communication several times with the control box a ST9420C after no previous issues!

I don't have the book for this particular unit but, check the sequencers that control the electric heat mode, as the regulator heat pump works good. The part may have a time or temperature delay that is too long for you. Also if it has a remote thermostat, check the heat anticipate setting. You will have to check the installation manuel, but its usually .6 to .8, but I don't think that is the problem.

I replaced the batteries, even though 'battery low' message was not displayed. this fixed my problem. I wish I'd have just done that to start with.

the cover pulls off if it has a green screen then most likely takes batteries if does not light up then no batteries with a small piece of insulated wire jump from green to red if indoor fan does not come on then transformer bad

Pull the power cord for 5 minute to reset the control board. if this control panel malfunction still exist after the reset, replace the control circuit board.
This is a typical control fault that should be corrected by pulling power for 5 minutes. if not, this reset will confirm major damaged to the circuit board.
