conditioner supply register.
3. The Thermostat must be installed in a
vertical position.

against the wall where the thermostat
will be mounted orienting it as shown
below.
2. Affix the mounting plate to the wall
using two screws. Wall anchors are
included if needed to secure the
mounting plate to the wall.

motorcoach:
Refer to the section "Wire Labeling
and Connectors" section in this
manual for wiring the thermostat.

for the equipment installed on the
coach.
