d. Mounting holes on the wallplate are designed
to fit a standard electrical box. If additional
mounting holes are required, mark the
locations on the mounting surface.
e. Remove the wallplate from the mounting
surface and drill any additional mounting holes
as needed at each of the marked locations.
f. Use the appropriate mounting hardware (field
furnished) for the specific mounting surface
and secure the wallplate to the surface.
4. Connect the air lines to the room thermostat. See
Clean Air Requirements on page 5 to ensure that
the air supply is clean, dry, and oil-free.
IMPORTANT: Avoid applying excessive pressure
while making the air line connections to the barbed
fittings on the room thermostat. Failure to do so may
damage the room thermostat and void the warranty.
5. Install the four 3.6 V lithium batteries included with
the room thermostat into the battery compartment.
Be sure to match the positive (+) battery ends with
the positive (+) battery terminals in the battery
compartment.
Note: The room thermostat can operate with just two
batteries installed; however, it operates for a
significantly shorter period of time. To maximize battery
life, we recommend that all four batteries be installed.
6. Once powered up, the room thermostat initializes
in:
a. 30 seconds if the room thermostat can connect
to a network.
b. 3 minutes if a network is not present.
IMPORTANT: Do not press any buttons during the
initialization process. Configuration changes made
during initialization are not saved.

7. Check the wireless connectivity at the intended
room thermostat installation location. It may take
approximately 30 seconds for the room thermostat
to initialize.
a. Look at the wireless connection status
indicator on the room thermostat LCD
(Figure 4). If
corner of the LCD, the wireless connection is
established and the room thermostat is
operating properly. If the LCD is blank in the
upper-right corner, there is no wireless
connection.
b. Look at the number of routes to the
WT-BAC-IP Gateway on the room thermostat
LCD (Figure 4). If the number of routes is
blank, the room thermostat is not connected to
the gateway. If the number 1 shows, there is
one connection. If the number 2 shows, there
are two or more connections and the room
thermostat is operating properly.
8. Attach the room thermostat to the previously
installed wallplate by aligning the slot in the room
thermostat housing with the top of the wallplate
and sliding the bottom of the room thermostat
housing over the bottom of the wallplate.
9. Document the device ID and the location of each
room thermostat on the floor plan.
