Minimum and maximum opening
The function allows you to set the minimum and maximum opening of the actuator in order to obtain the pre-set
temperature.
Protection - When this function is selected, the controller checks the temperature. If the pre-set temperature is
exceeded by the number of degrees in the Range parameter, then all actuators in a given zone will be closed (0%
opening).
Failsafe Mode – The function allows you to set the opening of the actuator heads, which will occur when an alarm
occurs in a given zone (sensor failure, communication error). The emergency mode of the thermostatic actuators is
activated in the absence of power supply to the controller.
The registered actuator can be deleted by selecting a specific one or by deleting all actuators at the same time.
WINDOW SENSORS
•
Settings
Enabled - the function enables the activation of window sensors in a given zone (window sensor registration
required).
Delay Time - This function allows you to set the delay time. After the preset delay time, the main controller responds
to the opening of the window and blocks heating or cooling in the respective zone.
CAUTION
If the delay time is set to 0, then the signal to the actuator heads to close will be transmitted immediately.
•
Wireless
Information – the screen displays the sensor data: battery level, range
The registered sensor can be deleted by selecting a specific sensor or all can be deleted at the same time.
FLOOR HEATING
In order to control the floor heating, you need to register and switch on the floor sensor: wired or wireless.
•
Floor sensor – the user has the option to register a wired or wireless sensor.
Hysteresis - Floor temperature hysteresis introduces a tolerance for floor temperature in the range of 0.1 ÷ 5°C, i.e.
the difference between the pre-set temperature and the actual temperature at which heating or cooling will start.
Calibration - Floor sensor calibration is carried out during assembly or after a longer period of use of the room
controller, if the displayed floor temperature deviates from the actual one.
•
Operation modes:
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 profile – 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.
