ACTUATORS

➢ Settings
•
SIGMA - the function enables seamless control of the electric actuator. The user can set the minimum and
maximum openings of the valve – this means that the degree of opening and closing of the valve will never
exceed these values. In addition, the user adjusts the Range parameter, which determines at which room
temperature the valve will start to close and open.
CAUTION
The Sigma function is only available for radiator actuators.
Example:
Zone preset temperature: 23˚C
Minimum opening: 30%
Maximum opening: 90%
Range: 5˚C
Hysteresis: 2˚C
With the above settings, the actuator will start to close once the temperature in the zone reaches 18°C (preset temperature
minus the range value). The minimum opening will occur when the zone temperature reaches the set point.
Once the set point is reached, the temperature in the zone will start to drop. When it reaches 21°C (set temperature minus
hysteresis value), the actuator will start to open - reaching maximum opening when the temperature in the zone reaches
18°C.
•
Protection - When this function is selected, the controller checks the temperature. If the set temperature
is exceeded by the number of degrees in the
closed (0% opening). This function only works with the SIGMA function enabled.
•
Emergency Mode – The function allows setting the opening of the actuators, which will occur when an
alarm occurs in a given zone (sensor failure, communication error).
➢ Actuator 1-6 - option enables the user to register a wireless actuator. To do this, select
the communication button on the actuator. After successful registration, an additional
appears, where the users can view the actuator parameters, e.g. battery status, range, etc. It is also possible to
delete one or all actuators at the same time.
