3. Carefully pull the locking tabs on the right side of
the mounting base and unlock the PCB. Open the
PCB to the left as illustrated in Figure 2.

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

8. Swing the PCB back to the right, and carefully
snap it into the locking tabs on the mounting base.
9. Remove the screw terminal blocks that are
attached to a disposable adhesive. Figure 4
illustrates the locations of the screw terminal
blocks on the thermostat controller.
