NOTE! If there are separate RC and RH wires, CUT the internal RC=RH jumper on the
back of the thermostat circuit board. See picture below.
Single Stage Heat Pump HVAC System Wiring to the Thermostat
If you have additional wires, see the wiring diagrams on page 5 and 6.
Check that the wires are screwed into the terminal blocks firmly.
Gently pull on the wires to confirm the connection.
Push all the excess wiring back into the wall.
Cut jumper to allow connection of separate RC and RH wires.
Connect the wires as marked from the HVAC
system to the corresponding terminals on the
thermostat back.
*C wire (24VAC common)
Heat Pump systems usually have the C wire
connected to the thermostat. If there isn’t a C
wire, batteries must be installed.
** O or B wires connect to the W2/O terminal on
the thermostat.
Connect the R wire to either RC or RH terminals.
