• Always place the thermostat according to local regulations on IP classes.
• Do not place the thermostat on the inner side of a poorly insulated exterior wall.
• Always install the thermostat at least 50 cm from windows and doors, due to draft, when using regulation in: floor and room mode or room alone mode.
• Do not place the thermostat in a way that it will be exposed to direct sunlight
• Note: A floor sensor is recommended in all floor heating applications and mandatory to thin mats under wooden floors to reduce the risk of overheating the floor.
• Place the floor sensor in a protecting plastic conduit in the floor construction in an appropriate place, where the floor is not exposed to sunlight or draft from door openings.

IMPORTANT DURING SET-UP
Select whether only a floor sensor or a combination of room and floor sensors should be used. A “room only” option is also available, but requires that you have to break the small plastic seal on the back of the display module, e.g. using a screwdriver; it will be possible to set the maximum floor temperature up to 45°. Furthermore, it will be possible to use only a room sensor. However, this option is not recommendable due to an increased risk of overheating the floor.

IMPORTANT: When the thermostat is used to control a floor heating element in connection with a wooden floor or similar material, always use a floor sensor and never set the maximum floor temperature to more than 35°C.
Note: Please contact the floor supplier before changing the maximum floor temperature and be aware of the following:

• The floor temperature is measured there, where the sensor is placed.
• The temperature of the bottom of a wooden floor can be up to 10˚C higher than the top.
• Floor manufacturers often specify the max. the temperature on the top surface of the floor.
