Optional Settings For Additional Thermostat Features

The Model 8553 thermostat is equipped with 5 DIP switches located inside the thermostat on the printed circuit board.

The DIP switches can however be changed to customize the thermostat’s operation to your particular needs. This should only be done after consulting with your contractor.

The Model 8553 DIP switches control the following functions:
