Since the Pearl thermostat didn't work as expected, I have another non-communicating thermostat installed and it works correctly so I'm reasonably assured that the wiring is correct. The photo I've attached is of the currently installed thermostat but the wiring for the Pearl was to the same terminals.
I do have a photo of the old/previous thermostat wiring but it was connected to a heat pump. I got rid of the heat pump and instead installed an A/C only unit.
I was hoping that there might be a setting in the thermostat menu that is causing this behavior. Does anyone have a Pearl Thermostat connected to an A/C only unit that could share their thermostat menu settings? THANKS FOR ALL OF THE HELP!
I have 2 pearls but heating only sorry... maybe remove the jumper between RH & RC? - not sure why this would matter though. Otherwise the wiring looks good to me.
Since I have a second Pearl thermostat I swapped them and the second one works just fine with the A/C. I guess the first one is bad. I bought both brand new from Amazon. (I need the other one for my heat only so if it works for heat then I’m good to go.). THANKS EVERYONE FOR THE HELP.
i got this one from amazon .. returning.. exact same issue when only w1 and rh were hooked up heat was always on even when therm was below setpoint and i could here it click off. these must be defective. i should hook up a wire and multimeter if i can find it and see what the resistance is..
Thanks for the heads up, will keep an eye out. I bought mine on Amazon a while ago and they seem to be working okay. Using them for in-floor heating - both battery operated.. mine use W1 and RH.
I've had one sitting here for a while that I meant to install and just did today. Using it with the built in thermostat controller app. So far it seems to be behaving properly....but I've only let it run a few cycles. I'll be keeping an eye on it.
