I’m not sure if something has changed in the device handler or the thermostat itself, but previously, I could set the heating and cooling setpoints to the same temp (not using auto mode) for my CT-100. Now, when I set the cooling setpoint, it changes the heating setpoint, and it doesn’t seem entirely cooperative in changing them back. Looks like it’s trying to keep about a 3 degree separation between the two.
If it helps, I’m trying to use the DH in conjunction with webCoRE. I haven’t had any issues until temps started to cool this year. Is this expected behavior that I (for some reason) wasn’t seeing before? Or has something changed?
I want to keep a fairly constant temp when I’m home. I just want to use +2/-2 increase/drop in temp to determine which mode needs to be active. Any thoughts as to what’s happening?
Edit: to add Thermostat model
