ELECTRICAL SHOCK HAZARD.
Follow local codes and ordinances when installing this
thermostat. Improper handling can cause serious
injury or death.
CAUTION
1. Disconnect power supply to prevent electrical
shock or equipment damage.
2. When connecting with aluminum conductors, use
CO/ALR solderless wire connectors to avoid fire
hazard.
3. To avoid damaging the sensing element, do not
remove thermostat cover until wiring is complete.
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
Disconnect power to the thermostat to prevent electrical
shock or equipment damage. All wiring must comply
with local electrical codes and ordinances.
Remove the old thermostat from the wall, taking care
not to damage the wiring insulation.
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.
Do not remove the T410 Thermostat Cover. Using wire
connectors approved for No. 12 wires, make line voltage
connections directly to the leadwires on the thermostat.
See Figs. 2 and 3 for typical wiring connections.
Prebend and push solid wires into the outlet box.
Remove thermostat cover by grasping the top and
bottom cover edge and pulling it outward away from
the thermostat base.
Turn the temperature setting dial so the setpoint
indicator is at the 12 o'clock position to prevent
damaging the dial stop.
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.
