1 WHP Connecꢀon for Electric heat output is used
for Heat Pump or the strip heat accessory for the
A/C.
The connectors of the thermostat can accept 20
AWG solid wire. To insert a wire, strip the wire to
the appropriate length (5/16”). The stripped length
can be checked by using the strip gage on the back
of the thermostat. Press the stripped wire into the
connector unꢀl the iniꢀal resistance is overcome.
Lightly tug on the wire to ensure the connecꢀon is
solid.
To remove a wire, press down on the connector’s
tab with a screwdriver and pull wire verꢀcally. It
won't take much force to pull the wire to remove it.
If the thermostat had wires previously inserted into
one of the connectors, it is recommended to use
the same gauge wire in that posiꢀon or a larger
(diameter) gauge wire.
Thermostats equipped with plugs (9420-382):
Reference illustraꢀon below for connectors.
If the wires are cut to remove the plugs, the wires must be spliced (or terminated) following the electrical
code and using good workmanship pracꢀces.
