T410A,B ELECTRIC HEAT THERMOSTATS

68-0145EF
Location
Install a vertical outlet box, which is used to mount the
thermostat, about 5 ft (1.5 m) above the floor in an area with
good air circulation at room temperature.
Do not install the thermostat where it may be affected by:
— drafts or dead spots behind doors, in corners or under
cabinets.
— hot air from convectors.
— radiant heat from sun or appliances.
— concealed pipes and chimneys.
— unheated (uncooled) areas such as an outside wall behind
the thermostat.
Wiring and Mounting
CAUTION
1. To avoid damaging the sensing element, handle the
thermostat with care.
2. Use a separate limit control in the heating
appliance.
3. To prevent damage to dial stop when mounting the
thermostat, turn the temperature setting dial until
the setpoint indicator is at the 12 o’clock position.
Replacement Applications
1.
Disconnect power to the thermostat to prevent electrical
shock or equipment damage. All wiring must comply
with local electrical codes and ordinances.
2.
Remove the old thermostat from the wall, taking care
not to damage the wiring insulation.
3.
Check the old wire insulation for cracks, nicks or fraying.
If necessary, apply approved electrical tape to insulate
old wires or replace with new wires.
4.
Do not remove the T410 Thermostat Cover. Using wire
connectors approved for No. 12 wires, make line volt-
age connections directly to the leadwires on the thermo-
stat. See Figs. 2 and 3 for typical wiring connections.
5.
Prebend and push solid wires into the outlet box.
6.
Remove thermostat cover by grasping the top and bot-
tom cover edge and pulling it outward away from the
thermostat base.
7.
Turn the temperature setting dial so the setpoint indica-
tor is at the 12 o’clock position to prevent damaging the
dial stop.
8.
Mount the thermostat on the outlet box. Tighten the two
mounting screws (included) to secure the thermostat,
taking care to avoid excessive pressure on the setting
dial. See Fig. 4.
