Hi Goodman Experts,
Just had a new heatpump system CPRT60 and variable speed AEPF4260 handler installed by a licensed installer, hooked to a Honeywell Vision Pro TH8321U1006 Thermostat. Problem is that if the system type is set to HEATPUMP (option 2) in the thermostat, the system cools great, but *never* shuts off, even if the system is set to off on the thermostat. Both the indoor and outdoor units continue to run.
If the system type is set to 1 in the thermostat, (1 conventional cool(a/c), 1 conventional heat) the system cools fine AND shuts off when temperature reached.
The installer thinks the Vision Pro is defective, but I have tried another thermostat and the results are exactly the same, (never shuts off when cooling) when system type is heatpump.
So, what did the installer miss? Is there something that needs to be set (jumper??, switch) on the airhandler that would cause this behavior? He says he's not totally up on Goodman stuff.
Thermostat wiring appears to be correct.
Thanks in advance!
