I got my parents a CT-30 Thermostat for Xmas. We installed it and setup programming, but the thermostat doesn’t seem to be following the schedule. We can manually change the temp and it follows that, but it won’t follow when the time changes.
Holiday isn’t set.
you can setup with the web portal or the phone app.
I suggest try the other one.
Make sure it’s not in “HOLD” mode.
It may be in simple mode. IIRC when in simple mode it does not follow the schedule. I can’t remember exactly how to change it, I think it has to be OFF, then MENU and hold PROGRAM for 12 second. You can find videos with instructions on Youtube.
