Application

This thermostat is designed to control an electric heating system such as a baseboard heater, a radiant ceiling, a convector or a fan-forced heater. The thermostat CANNOT be used with:

• a resistive load under 1.25 A
• a resistive load over 12.5 A
• a system driven by a contactor or a relay (inductive load)
• a central heating system.

Installation guidelines

TURN OFF POWER TO THE HEATING SYSTEM AT THE MAIN POWER PANEL TO AVOID ELECTRICAL SHOCK.

•  All cables and connections must comply with local electrical codes.
• This thermostat has tinned copper wires for line and load connec- tions. Special CO/ALR solderless connectors must be used if these wires will be connected to aluminium conductors.
• Install the thermostat onto an electrical box.
• Install the thermostat about 1.5 m (5 feet) high, on an inside wall facing the heater.
• 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 stove pipes.
• The thermostat wires are not polarized; either wire can be con- nected to the load or to the power supply.
