Thermostat Does Not Display "Heat Pump" during Cooling
Greetings. I have a 14-year-old Waterfurnace NDV049A111CTR. The two thermostats are Waterfurnace TA32W02 (manufactured by Emerson). The system provides heating and cooling as expected.
During heating, the thermostats display "Heat Pump." When I switched to cooling for the first time this year, I noticed that "Heat Pump" was not displayed. Cooling operation was normal.
The thermostat manual says that the "Heat Pump" indicator means that the "thermostat is configured for Heat Pump."
I don’t recall whether "Heat Pump" was displayed during cooling in past years.
Is it OK for the thermostat to show "Heat Pump" during heating but not during cooling? Is there a way to check whether the system uses the heat pump during cooling?
Many thanks for any help.
