No battery warning from hard-wired Wall Smart Thermostat’s
Just wondered if anyone else has had this issue like me?
I recently went to a wall thermostat to check the room temperature and noticed the display was not working correctly and very erratic. I checked the device in the app but it was showing the batteries as been “good” and the device also still controlled the heating circuit.
I replaced the batteries on four of the five Thermostats and all display correctly now.
Still not sure why the battery warning never appeared?
