Wiring—conventional systems
Alternate wiring (conventional systems)
If labels do not match terminals, connect wires as shown below (see notes, below).
NOTES:
1. If you must connect both R and Rc wires, set the R Slider Tab to the down
position (2 wires).
2. If your old thermostat had both R and RH wires, set the R Slider Tab to the
down position (2 wires). Then connect the R wire to the Rc terminal, and the
RH wire to the R terminal.
3. If your old thermostat had only 1 C or C1 wire, connect it to the C terminal. If
your old thermostat had 2 C or C1 wires, wrap each separately with electrical
tape and do not connect them.
