T600HCx-3 Single-Stage Thermostats Installation Instructions
2
To install the thermostat:
1.
Use a Phillips-head screwdriver to remove the
security screw on the bottom of the thermostat
cover.
2.
Pull the bottom edge of the thermostat cover and
open the thermostat as illustrated in Figure 1.
3.
Carefully pull the locking tabs on the right side of
the thermostat mounting base and unlock the
Printed Circuit Board (PCB). Open the PCB to the
left as illustrated in Figure 2.
4.
Pull approximately 6 in. (152 mm) of wire from the
wall and insert the wire through the hole in the
thermostat mounting base.
5.
Align the thermostat mounting base on the wall and
use the base as a template to mark the two
mounting hole locations.
Note:
Be sure to position the thermostat mounting
base so that the arrow on the base points upward to
indicate the top of the thermostat.
6.
Drill a 3/16 in. (5 mm) hole at each of the two
marked locations and tap nylon anchors (included
with the thermostat) flush to the wall surface.
7.
Position the thermostat mounting base on the wall
and use the two mounting screws (included with
the thermostat) to secure the base to the surface
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 thermostat mounting
base.
9.
Pull the pull-tabs on each of the connectors and
remove the screw terminal blocks as illustrated in
Figure 4.
