Single-Piece Installation
The following steps should befollowed for
the installation of the single-piece
configuration.
1. Remove cover from Equipment Control Module by pressing the two tabs
on the bottom edge and pulling away. Route wires through large hole in
Equipment Control Module. Level Equipment Control Module against
wall (for aesthetic value only - Equipment Control Module need not be
leveled for proper operation) and mark wall through 4 mounting holes.
To avoid unintended bending of wall plate plastic, use all 4 screws and
anchors.
2. Drill four 3/16-in. mounting holes in wall where marked. Thermostat
may be mounted to a standard junction box if desired. Hole pattern on
Equipment Control Module matches junction box mounting holes.
3. Secure rear plastic Equipment Control Module to wall with 4 screws and
anchors provided. To avoid unintended bending of wall plate plastic, use
all 4 screws and anchors. Make sure all wires extend through hole in
Equipment Control Module.
4. Adjust length and routing of each wire to reach proper connector block
and terminal on Equipment Control Module with 1/4-in. (6 mm) extra
length. See Fig. 14.
