3. Align the thermostat controller mounting base on the wall with the security screw on the top
and use the base as a template to mark the two mounting hole locations. See Figure 3.
Note:
- If you need to install the thermostat controller on an electrical junction box, use 2-1/2 in.
x 4 in. (63 mm x 101 mm) square boxes with mud ring covers and avoid smaller 1-1/2 in.
x 4 in.(38 mm x 101 mm) square or 3 in. x 2 in. (76 mm x 51 mm) boxes. This procedure
ensures that you have enough space for cabling, if needed.
- For surface-mounted applications, use durable mounting hardware, such as wall
anchors, that cannot be easily pulled out of the mounting surface.
4. Pull approximately 6 in. (152 mm) of wire from the wall and insert the wire through the center
hole in the thermostat controller mounting base. See Figure 3.
5. Secure the mounting base to the wall surface using two mounting screws (user supplied) as
illustrated in Figure 3.
Note:
Be careful not to overtighten the mounting screws.
