Recent install with several bldgs. Combination of standard Heat Pumps MX2-HB36NA and City Multi heat pumps PUMY-P48NHMU.
We provide HW baseboard.
Found several units running on AC during coldest weather. I'd like to lockout cooling until 60 O.A. but am stymied by Mitzi. No can do.
I know the stat talks to the condenser so it wouldn't like any outside controls. Anybody have any ideas?
