WIRING THE THERMOSTAT
(Refer to the examples on the following page.)
24 V (ac) Power
Connect the 24 V (ac) power to the R and C terminals of the thermostat. This connection
provides power to the microprocessor and display of the thermostat.
Heat Relay (Rh - W)
The Heat Relay Rh - W terminals are an isolated output. There is no power available
on these terminals from the thermostat. These terminals are to be used as a switch for
a 24 V (ac) circuit. This circuit can operate a low current 24 V (ac) device directly or an
external relay to enable a line voltage or high current device.
STEP SIX
INSTALLING THE FRONT COVER
Align the hinges on the bottom of
the front cover with the bottom of the
thermostat mounting base. Pivot the
front cover around the bottom hinges
and push the top against the mounting
base until it snaps firmly in place.
