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.
4. C does not power the thermostat display or operations; batteries are always
required.
