- The Base is removed by loosening all captive screws.
- The switching subbase is removed by unscrewing the mounting screws that hold it on the wall or adaptor plate.
- Remove the front cover of the old thermostat. With the wires still attached, remove the wall plate from the wall.
- If the old thermostat has a wall mounting plate, remove the thermostat and the wall mounting plate as an entire assembly.
- Identify each wire attached to the old thermostat.

Battery Location
The thermostat can function on 2 x “AA” alkaline batteries as an alternative source of power. If 
change is displayed, the batteries are low and should be replaced. For best results, replace batteries once a year. To replace batteries, install the batteries along the top of the base. The batteries must be installed with the positive ( +) ends to the right
