Placement of thermostat
• Select an indoor wall and a position 1.3 m to 1.5 m above the
floor.
• Ensure that the thermostat is away from direct sunlight.
• Ensure that the thermostat will not be heated through the wall by
sunshine.
• Ensure that the thermostat is away from any source of heat, for
example television set, electronic equipment, fireplace,
spotlights, and so on.
• Ensure that the thermostat is away from any source of humidity
and water splashes (IP20).
Label thermostat
Label the thermostat, where suitable, with the channel numbers they
are to control, for example, #02, #03. For a system with several room
controllers, add the ID of each room controller, for example, 1.02,
1.03, 2.02, 2.03.
If an external sensor is connected, add information about sensor type
when applicable.
Available thermostat and sensor combinations:
• Room temperature
• Room and floor temperature
• Room and outdoor temperature
• Remote sensor temperature
Connect external sensor to thermostat
1. Insert the two wires from the sensor cable (non polarized) into
the removable connector.
2. Tighten the screws fixing the wires in the connector.
3. Insert the connector on the input pegs on the thermostat.
Note
For accurate temperature: attach the outdoor sensor to
the north side of the building where it is unlikely to be
exposed to direct sunlight. Do not place it close to doors,
windows, or air outlets.
The external temperature sensor input can be used for either a floor,
outdoor or remote temperature sensor. Use the software on the
thermostat to select a control mode which corresponds to the use of
the sensor and thermostat.
