4. Install the wall plate on the wall box using the screws furnished with the instrument.
Note that the wall plate has key slotted holes to allow insertion of the screws prior to
installation of the wall plate and also to allow leveling of the wall plate.
5. Carefully plug the thermostat into the wall plate.
NOTE: To facilitate plugging the thermostat into the O-rings in the adapter, wet or
moisten the thermostat supply and return ports. This wetting or moistening
will lubricate and allow the thermostat to slip through the O-rings more easily.
6. Install the cover.
The installation is now complete.
