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.

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.

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.

Save packages of screws, instructions, receipt and

proof-of-purchase.

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.

REMOVE OLD THERMOSTAT

WARNING

Begin by turning off power to the heating circuit at

the main service panel.

Contact you local waste management authority for

instruction regarding recycling and the proper

disposal of a old control.

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.
