•direct heaters

• radiant panels

• electric fl oor heating

PT14-PPT14-P

Install the thermostat at a suitable place where its operation cannot be affected by direct fl ow
of hot air from the heater, sunshine or other disturbing effects. Neither install it on an external
wall. The installation height should be approx. 1.5 m above the fl oor. Place the thermostat in
the “reference room”, such as the living room (the heating source will switch according to the
temperature in this room).

The installation must only be done by a properly qualifi ed person!

Before installation, disconnect the power supply!

INSTALLATION PROCEDURE
