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.
