Explanation of Thermostat Jumpers
Jumpers are located on the back of the thermostat.
Figure 7: Thermostat Jumpers
This jumper congures
the thermostat to control a
conventional gas/electric system
or a heat pump. If your system is
anything other than a heat pump,
leave this jumper set for GAS/
ELEC.*
* For some commercial heat
pumps, this jumper will need to
be set for GAS/ELEC. Consult the
commercial heat pump literature.
When J1 is congured to control
a heat pump:
This jumper (J2) must be set to
control the appropriate reversing
valve. If RV=O is chosen, the
W1/O/B terminal will energize in
cooling. If RV=B is chosen, the
W1/O/B terminal will energize in
heating.
When J1 is set for GAS/ELEC:
This jumper (J3) controls how
the thermostat will control the
Fan (G) terminal in heating
mode. When GAS is chosen,
the thermostat will not energize
the Fan (G) terminal in heating.
When ELEC is chosen the
thermostat will energize the fan
in heating.
