Note
The floor sensor measures the temperature of the concrete in the floor. The temperatures of the floor surface materials are usually about 5 ° C lower than the temperatures of the concrete.
– It is recommended that the limit temperature of the floor sensor be set as low as possible to avoid damaging the floor surface material. However, each material is unique, so check the material manufacturer’s recommendations.

Floor controlling:
– The thermostat controls the floor temperature.
– For the application "Floor controlling" a floor sensor must be connected.
– If there is no floor sensor connected, there will be displayed the note "Sensor floor error".
Room controlling:
– The thermostat controls the room temperature on the basis of the internal sensor (air temperature).
Room controlling / floor limitation:
– The thermostat controls the room temperature on the basis of the internal sensor and also monitors the floor temperature to adjust the control depending on extreme floor temperature values.
– The user sets the minimum and maximum temperature limit for the floor. The maximum limit is set to protect wooden floors from being destroyed due to excess temperatures. So even if the internal sensor requests more heat, the thermostat won’t switch on. The minimum temperature keeps the floor warm when there are other heat sources in the room e.g. a fire place. So even if the internal sensors measures a sufficiently warm room, the thermostat will control the floor temperature to be on a certain minimum level.
– For the application "Room controlling / floor limitation" a floor sensor must be connected.
– If there is no floor sensor connected, there will be displayed the note "Sensor floor error".
