Wiring the Controller
The KE2 Temp was designed with simplicity in
mind. The controller accepts 120V / 208-240V
to power the controller and 12V - 240V solenoid
voltage via the liquid line solenoid relay through
the lower conduit connection. The temperature
sensor and communication wires are attached
via the upper conduit connector.
After the four screws have been detached from
the lower section, the cover may be gently
moved to the side.

Next remove the high voltage protective cover.

With the high voltage cover removed, the two
screw terminal connectors can be seen. The
2-position connector is the controller’s power
supply. The voltage selector switch should be
positioned to match the voltage supplied.
