Guidelines
Turn off power to the heating system at the main power panel to
avoid electrical shock. Installation should be carried out by an
electrician.
All work must conform to the applicable country standards for

electrical installations and wiring.
This thermostat should be connected on a circuit equipped with

a fuse or a circuit breaker. It must be installed on a certified
electrical box equipped with non-metallic cable strain relief
adapters. Use separate adapters for the high-voltage wires and
for the sensor cable.
For a new installation, choose a location about 1.5 m above the

floor.
For electric baseboards, convectors and fan-forced heaters, the

thermostat must be installed facing the heating system and on
an inside wall.
Avoid locations where there are air drafts (top of staircase, air

outlet), dead air spots (behind a door), direct sunlight or
concealed chimneys or stove pipes.
NOTE: The terminals are designed to handle a cross-section of wire

measuring 0.33 to 3.1 mm .
