Preparation

1. proper installation of your thermostat will occur if you follow these instructions STEP-BY-STEP. It is recommended that as you read, understand and complete each step, you check it off with a pencil or pen.
2. Check thermostat suitability for your home’s system by reviewing the ratings listed above.
3. Make certain that your heating system is working, especially if it has been inoperative for a length of time. If the system does not work, contact your local electrician for assistance.
4. carefully unpack your new thermostat. To avoid damage to the sensing element, do NOT remove the thermostat cover until the wiring has been completed.
5. Save packages of screws, instructions, receipt, and proof of purchase.

Thermostat Mounting Dimensions

Remove Old Thermostat

WARNING Electrical Shock Hazard. Can cause severe injury, death or property damage.
Begin by turning off power to the heating circuit at the main service panel.

1. Remove cover of old thermostat—cover normally snaps off when pulled firmly from the bottom. If it resists, check for a screw that locks the cover.
2. Loosen screws holding thermostat base to outlet box and lift away.
3. Disconnect wires from old thermostat. As you disconnect each wire, tape the end and label it with the letter of the terminal designation to make reconnection to new thermostat easier.
4. Check the old insulation for cracks, nicks or fraying, and apply high quality plastic tape where necessary for adequate insulation.
5. Retain the old thermostat for reference purposes and until your new thermostat is functioning smoothly.

Wire and Mount New Thermostat

1. Turn the temperature setting knob to 65°F (18°C). This will prevent accidental damage to the knob stop during mounting.
2. Remove thermostat cover by grasping the top and bottom ends with fingers, and pulling outward.
3. Connect wires to the thermostat as shown in the applicable wiring diagram. Push the wires into the outlet box, and insert the thermostat into the box for mounting by pushing against top and bottom of the thermostat base.
   IMPORTANT
   Do not press on setting knob. Rough handling or strong pressure can damage knob or sensing element, and change calibration.
4. Secure the thermostat to the box with the two captive mounting screws provided.
5. Replace thermostat cover.
6. set knob to desired room temperature.

• POWER SUPPLY. PROVIDE DISCONNECT MEANS AND OVERLOAD PROTECTION AS REQUIRED.
• BREAKS ON POSITIVE OFF.
• EXPOSED UNUSED LEADWIRES TO BE PROPERLY INSULATED.
  THERMALLY ACTIVATED—BREAKS ON TEMPERATURE RISE. MAKES ON TEMPERATURE FALL.

CAUTION:
SPECIAL SERVICE CO/ALR SOLDERLESS CONNECTORS MUST BE USED WHEN CONNECTING WITH ALUMINUM CONDUCTORS; OTHERWISE, A FIRE HAZARD CAN RESULT.

Check Out Thermostat

1. Turn on the power to the heating system.
2. Turn the setting knob all the way clockwise; listen for a clicking sound as the switch makes contact. The electric heater should begin operation.
3. Turn the knob all the way counterclockwise; listen for a clicking sound as the switch breaks contact. The electric heater should shut off.

Setting Thermostat

1. Begin by setting the knob at 70°F (20°C) on the scale.
2. If this setting is not satisfactory after at least two hours of operation, turn the setting knob up to raise the temperature, or down to lower the temperature. Move knob only a degree each time.

Troubleshooting

Your thermostat requires little or no attention. Most problems can generally be traced to the following:

Symptom	Checkout	Action
No heat.	Make sure power is on at main service panel. Turn the temperature setting knob fully clockwise .	Heater should start to warm up within two minutes. If not, contact a qualified electrician to check the thermostat and heater.
	Improper connections to the thermostat.	With power to circuit OFF, tighten all wiring connections. Repair any frayed or broken wires.
	Other.	Contact a qualified electrician for assistance.
Heater never turns off.	Turn the temperature setting knob fully counterclockwise.	Heater should start to cool within minutes. If not, turn off power at the main service panel, and contact a qualified electrician.
The thermostat setting and thermometer reading disagree.	The thermostat is affected by drafts or radiant heat.	Contact the electrician to change the location. The thermostat should be about 5 ft (1.5m) above the floor and on an inside wall.
	The thermometer is out of calibration.	Recalibrate. See “Recalibration Procedure” on page 6.

Calibration

The CT62 Thermostats are calibrated at the factory using precise instruments under closely controlled conditions. Recalibration should not be necessary. Allow the thermostat to operate for several hours before checking the calibration. The CT62 Thermostat vapor-filled dual diaphragm sensing element is affected by barometric pressure and altitude. Temperature deviations of 1°F (0.5°C) are normal. If the thermostat is mounted in a suitable location and still appears out of calibration, check calibration as follows:
Check Calibration

1. Turn the setting knob clockwise until the switch makes (a clicking sound).
   The heating equipment and fan start.
2. No recalibration is necessary if the thermostat switch makes with the thermostat set at the same temperature as indicated on the thermometer.
3. If the thermostat setting differs from the thermometer, record the temperature difference and recalibrate as instructed in the Recalibration Procedure section.

Recalibration Procedure

1. Note the temperature difference between the temperature setting and the thermometer.
2. Remove the thermostat cover.
3. Rotate the setting knob clockwise until you hear the switch click.
4. Hold the setting knob firmly and rotate the set point scale ring counterclockwise until the 12 o’clock position of the ring agrees with the cover thermometer.
5. The heat from your hand will affect the diaphragm sensor. Replace the thermostat cover, wait five minutes, and recheck calibration.
