OPERATING YOUR THERMOSTAT
Before you begin programming your thermo- stat, you should be familiar with its features and with the display and the location and operation of the thermostat buttons. The information in this section will help you become familiar with your new thermostat so that you can easily program it.
Your thermostat consists of two parts: the thermostat body and the subbase.
!CAUTION
Remove power from the system at the circuit breaker/fuse box before remov- ing or attaching the thermostat body. Equipment damage and/or personal in- jury could occur.
The subbase is attached to the wall, but you can remove the thermostat body for easy program- ming. To remove the thermostat body from the subbase, grasp the thermostat body and gently pull it straight out from the subbase. To attach the thermostat body, line up the six terminal pins on the upper section of the thermostat back with the matching connector on the subbase. Insert
