T600HCx-3 Single-Stage Thermostats Installation Instructions 3
To wire the thermostat:
1. Strip the ends of each wire a 1/4 in. (6 mm) and
connect them to the appropriate screw terminals as
indicated in Figure 5.
2. Carefully push any excess wire back into the wall.
Seal the hole in the wall with fireproof material to
prevent drafts from affecting the ambient
temperature readings.
3. Reinsert the screw terminal blocks onto the PCB.
4. Reattach the thermostat cover to the mounting
base (top side first).
5. Use a Phillips-head screwdriver to reinstall the
security screw on the bottom of the thermostat
cover.
