Your Honeywell Thermostat
Your new Honeywell T410 Electric Heating Thermostat provides line voltage control of a radiant cable, electric baseboard, and resistive-rated fan forced heaters within the ratings listed above.
WARNING
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.
MERCURY NOTICE
If this control is replacing a control that contains mercury in a sealed tube, do not place you old control in the trash. Dispose of properly.
Contact you local waste management authority for instruction regarding recycling and the proper disposal of a old control.

INSTALLATION INSTRUCTIONS
1PREPARATION
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.
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.
Carefully unpack your new thermostat. To avoid damage to the sensing element, do NOT remove
the thermostat cover until wiring has been completed.
Save packages of screws, instructions, receipt and proof-of-purchase.
2REMOVE OLD THERMOSTAT
WARNING
Begin by turning off power to the heating circuit at the main service panel.
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.
Loosen screws holding thermostat base to outlet box and lift away.
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.
Check the old insulation for cracks, nicks or fraying, and apply high quality plastic tape where necessary
for adequate insulation.
Retain the old thermostat for reference purposes and until your new thermostat is functioning
smoothly.
