System Switch Selection
The body of the thermostat has two switches on the backside. They
are accessible by removing the backplate from the body. The installer
should set these to match the system.
If the thermostat is controlling a heat pump system, set the first switch
to Heat Pump. Set the second switch based on the type of the backup
heating system.
If the thermostat is controlling a non-heat pump system, set the first
switch to Non-Heat Pump. The second switch must be set to match the
system as Gas or Electric.
If Non-Heat Pump and Gas are selected, the heating system will control
the fan.
If Non-Heat Pump and Electric are selected, the thermostat will control
the fan.
If Heat Pump is selected, the thermostat will control the fan.
Connecting the Wires
1. The wire ends should be stripped back 8 mm (5/16 in.).
2. Use the Wiring Diagrams and secure the wires into the terminal strip.
If replacing another thermostat, the wires should have been labeled.
Match the labels to the terminals. Tighten the screws.
3. Pull lightly on each wire to ensure the connection is secure.
NOTE: Nightlight feature is only enabled when the RH/R and C terminals
are connected.
