This programmable thermostat can be used to control an electric
heating system such as an electric baseboard heater, a radiant ceil-
ing, a radiant floor, a convector, etc.
The thermostat cannot be used with the following:
• a resistive load greater than 16.7 A
• a resistive load less than 2 A
• a system driven by a contactor or relay (inductive load)
• a central heating system
• One (1) thermostat
• Two (2) 6-32 screws
• Two (2) solderless connectors
TURN OFF POWER TO THE HEATING SYSTEM AT THE MAIN
POWER PANEL TO AVOID ELECTRICAL SHOCK.
THE INSTALLATION MUST BE PERFORMED BY AN ELECTRI-
All cables and connections must conform to the local electrical
Special CO/ALR solderless connectors must be used when con-
necting with aluminum conductors.
Install the thermostat onto an electrical box.
Install the thermostat about 5 feet high, on an inside wall facing
Avoid locations where there are air drafts (such as the top of a
staircase or an air outlet), dead air spots (such as behind a
door), or direct sunlight.
Do not install the thermostat on a wall that conceals chimney or
The thermostat wires are not polarized; either wire can be con-
nected to the load or to the power supply.
NOTE: Always keep the thermostat's vents clean and unobstructed.
o Connect the thermostat wires to the line wires and to the load
wires using solderless connectors for copper wires.
p Push any excess wire back into the electrical box.
q Before installing the TH106 thermostat base, install provided
adapter plate (U-shaped) on 347V electrical box which is bigger
than regular electrical boxes.
NOTE: If necessary, before re-installing the front component, config-
ure the thermostat (see section 3).
