Honeywell thermostats typically consist of a base plate and a cover plate, which is attached to the wall. Generally speaking, to change the battery, you turn off power to your thermostat, remove the cover plate and swap out the old batteries. This series comes with an upgraded LED display that will notify you when the battery is running low and will display the current indoor temperature, the current day & time, and the current system status, among other useful metrics.

If i turn the thermostat up to 30 the heating stays on - i haven't waited till the room gets that hot. If i turn the thermostat down to 10 the heating stays off - it only does the 10min cycle when the room is at the set temperature ie room at 20, thermostat at 20. If the sensor status light starts flashing red, this means the battery charge is critically low, with only 2-3 weeks of use remaining. During regular operation, the status light remains switched off.
