4.1.8. FLOOR HEATING
➢ Floor Sensor
•
Sensor Selection - This function is used to enable (wired) or register (wireless) floor sensor. In the case of a
wireless sensor, register occurs by additionally pressing the communication button on the sensor.
•
Hysteresis - adds a tolerance for the room temperature in the range of 0.1 ÷ 5°C, at which the additional
heating/cooling is enabled.
Example:
The maximum floor temperature is 45°C
Hysteresis is 2°C
The controller will deactivate the contact after 45°C is exceeded at the floor sensor. If the temperature starts to
drop, the contact will be switched back on again after the temperature at the floor sensor drops to 43⁰C (unless the
set room temperature has been reached).
•
Calibration - Floor sensor calibration is carried out during assembly or after a longer period of use of the sensor,
if the displayed floor temperature deviates from the actual. Adjustment ranges from -10°C to +10°C, with a step
of 0.1°C.
CAUTION
The floor sensor is not used during the cooling mode.
➢ Operation mode
•
OFF – Selecting this option disables the floor heating mode, i.e.
•
Floor Protection – This function is used to keep the floor temperature below the set maximum temperature to
protect the system from overheating. When the temperature rises to the set maximum temperature, the reheating
of the zone will be switched off.
•
Comfort mode – This function is used to maintain a comfortable floor temperature, i.e. the controller will monitor
the current temperature. When the temperature rises to the set maximum temperature, the zone heating will be
switched off to protect the system from overheating. When the floor temperature drops below the set minimum
temperature, the zone reheat will be switched back on.
➢ Min. temperature
The function is used to set the minimum temperature to protect the floor from cooling down. When the floor
temperature drops below the set minimum temperature, the zone reheat will be switched back on. This function is only
available upon selecting Comfort
➢ Max. temperature
The maximum floor temperature is the floor temperature threshold above which the controller will switch off the
heating regardless of the current room temperature. This function protects the installation from overheating.
