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
connections. 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 connected
to the load or to the power supply.
