system such as a baseboard heater, a radiant floor, a radiant ceiling,
a convector, a fan-forced heater, etc.
The thermostat cannot be used with the following:
•
a resistive load under 2 A
•
a resistive load over 12.5 A
•
systems driven by a contactor or a relay (inductive load)
•
central heating systems

All cables and connections must comply with local electrical
codes.
This thermostat has tinned copper wires for line and load con-
nections. Special CO/ALR solderless connectors must be used if
these wires will be connected to aluminum conductors.
Install the thermostat onto an electrical box.
Install the thermostat about 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.
