A041_C - Outdoor Unit Not Supported
Status
This is a critical fault. The system will not operate.
Description
The system is not compatible either an outdoor unit is not allowed to be installed on the present air handler or the thermostat is not an 800 series thermostat. For example a (-)A18, (-)P18, (-)A20 or (-)P20 is matched with an RH2V or RH3V air handler rather than the proper RHMV Air Handler or a (-)A15**AZ, (-)A16**AZ or (-)P16**AZ mid tier inverter outdoor unit is connected to a (-)ETST700SYS thermostat.
Expected Operation
System will not operate
Solution
Resolve whichever mismatch in equipment or thermostat that is not correct.
