REASSEMBLING THE THERMOSTAT TO THE INSTALLED BACKPLATE

Before the thermostat is reassembled to the backplate, ensure the following:

* Polarity has been respected for the communication wires.

* All wires for peripheral components (SL-IDS, perimeter heat) are connected.

* Ensure all wires are properly inserted and screwed down in terminal blocks.

* Ensure dipswitches are set appropriately

Reassemble the thermostat as follows:

1. Position the housing assembly inside the access panel.

2. Position the housing and access panel assembly on the hinged tabs located at the top of the

installed backplate.

3. Gently swing the thermostat and access cover downwards and press on the bottom center

edge until it snaps into place.

NOTE: TEMPERATURE ACCURACY

Full temperature accuracy will only be realized after the thermostat has been installed and pow-
ered for at least one (1) hour.

INSTALLATION

1. Lift the thermostat access cover and insert a coin or large flat blade screwdriver into the

slot located in the bottom center of the case and twist 1/4 turn (be extremely careful not to
insert more than 1/8" [3 mm] into the casing, as this may damage the circuit board). Grasp
the lower corners of the thermostat body and separate from the thermostat backplate.
Swing the thermostat out from the bottom, and lift up and out of the base.

2. Place the rectangular opening on the thermostat backplate over the equipment control wires

protruding from the wall. Using the base as a template, mark the location of the two (2)
mounting holes. No leveling is required.

3. Use the supplied anchors and screws for mounting on the drywall or plaster. Drill two (2)

3/16" (5 mm) holes at the marked locations and tap nylon anchors flush to the wall surface.
Fasten the backplate to the wall.

4. Connect the control module wires to the thermostat terminal blocks. Connect the low volt-

age wires from the perimeter heat device if installed.

5. Push any extra or slack wire back into the wall. Dress the remaining wires so they are flush

to the mounting plate. The access hole should be sealed or stuffed to prevent drafts from the
wall affecting the thermostat.
