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 set point 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 lead wires 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 set point 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.

1. POWER SUPPLY. PROVIDE DISCONNECT MEANS AND OVERLOAD PROTECTION AS REQUIRED.
2. USE SPECIAL SERVICE CO/ALR SOLDERLESS CONNECTORS WHEN CONNECTING ALUMINUM CONDUCTORS OR A FIRE HAZARD MAY RESULT.
3. USE A SEPARATE LIMIT CONTROL IN THE HEATING APPLIANCE.
4. BREAKS AND REMAKES BELOW -31 F (-35 C); NORMALLY THERMAL ACTIVATED. BREAKS ON TEMPERATURE RISE; MAKES ON TEMPERATURE FALL.

New Applications

1. Disconnect power supply to prevent electrical shock or equipment damage. All wiring must comply with local electrical codes and ordinances.
2. Run line voltage wiring to the thermostat location.
3. 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.
4. Prebend and push solid wires into the outlet box.
5. Remove the thermostat cover by grasping the top and bottom cover edge and pulling it outward away from the thermostat base.
6. Turn the temperature setting dial so the set point indicator is at the 12 o’clock position to prevent damaging the dial stop.
7. 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.

SETTINGS AND CHECKOUT

Setting
The thermostat temperature setting can be adjusted by turning the setting dial clockwise or counterclockwise to the desired setting. See Fig. 5. To determine appropriate setting, allow the thermostat to operate for several hours.

Checkout
IMPORTANT
Make sure all wiring connections are tight before proceeding with Checkout.

Check out thermostat operation as follows:

1. Turn the setting dial fully clockwise; heating circuit makes and electric heater starts.
2. Turn the setting dial fully counterclockwise; the heating circuit breaks and the heater starts to cool.
