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 voltage connections directly to the leadwires on the thermostat. 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 bottom cover edge and pulling it outward away from the thermostat base.

7.Turn the temperature setting dial so the setpoint indicator 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.
