STEP 1
•
Using a multi-meter
determine which leg of
the thermostat is the
cycle leg and which is the
ON-OFF leg.
•
Do this by turning the
thermostat to the OFF
position and then turning
the knob until you notice
or hear a click. The leg
you read continuity on at
this point is the ON-OFF
side of the switch.
•
Turn the knob again until
you notice or hear the
second click, read
continuity across the
other leg and that is the
cycle side of the switch.
Mark those wires as you
will need them later in the
instructions.
