Your Honeywell Thermostat  
WARNING  
Your new Honeywell CT62 Electric Heating Thermostat  
provides line voltage control of a radiant cable, electric  
baseboard, and resistive-rated fan forced heaters within  
the ratings listed above.  
This thermostat is a line voltage control (120 Volts to  
240 Volts.) Do not install it if you are not completely  
familiar with house wiring. If handled improperly,  
there can be risk of a 120 Volt to 240 Volt electric  
shock hazard, which may cause serious injury or  
death.

PREPARATION  
Carefully unpack your new thermostat. To avoid  
damage to the sensing element, do NOT remove  
the thermostat cover until wiring has been completed.  
Proper installation of your Honeywell 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 pencil or  
pen.  
Save packages of screws, instructions, receipt and  
proof-of-purchase.  
Check thermostat suitability for your home’s system  
by reviewing the ratings listed above.  
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.

TROUBLESHOOTING  
Your Honeywell thermostat requires little or no attention. Most problems can generally be traced to the following:  
Symptom  
No heat.  
Checkout  
Action  
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 qualified electrician to check thermostat and heater.  
.
Improper connections to  
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 temperature setting  
knob fully  
Heater should start to cool within minutes. If not, turn off power  
at the main service panel, and contact qualified electrician.  
counterclockwise  
.
Thermostat setting  
and thermometer  
reading disagree.  
Thermostat affected by  
drafts or radiant heat.  
Contact electrician to change the location. The thermostat  
should be about 5 ft (1.5m) above the floor and on an inside  
wall.  
Thermometer is out of  
calibration.  
Recalibrate. See step 8.  
The heat from your hand will affect the diaphragm  
sensor. Replace thermostat cover, wait five minutes  
and recheck calibration.

CALIBRATION  
The CT62 Thermostats are calibrated at the factory using  
precise instruments under closely controlled conditions.  
Recalibration should not be necessary. Allow the thermo-  
stat 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:  
THERMOSTAT  
BASE  
Check Calibration  
Turn the setting knob clockwise until the switch  
makes (clicking sound). The heating equipment and  
fan start.  
No recalibration is necessary if the thermostat switch  
makes with the thermostat setting at the same  
temperature as indicated on the thermometer.  
If the thermostat setting differs from the thermom-  
eter, record the temperature difference and  
recalibrate as instructed in the Recalibration Procedure  
section.  
SETTING KNOB  
AT 12 O'CLOCK  
POSITION  
Recalibration Procedure  
Note the temperature difference between the  
temperature setting and the thermometer.  
SCALE RING  
Remove the thermostat cover.  
Rotate setting knob clockwise  
switch click.  
until you hear  
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.
