Control mode
Options: - 2-step
- PWM
- Continuous
- FanCoil
This function allows you to specify the type of control. You can choose
from 2-step control, PWM control, Continuous control or FanCoil control.
This parameter is only available if the "Cooling" or "Heat and cool" control
functions are used.
Hysteresis
Options: - 0.0 K
- 0.1 K
- 0.2 K
- 0.3 K
...
- 1.0 K
...
- 2.0 K
Set a hysteresis value to ensure that the valve does not constantly switch
with each minor under and overshoot when using 2-point control of the
actuator. The hysteresis value lies around the setpoint. For example, if
the setpoint is 26 °C and the hysteresis is 1 K, the room thermostat when
cooling sends only an "on" signal at 25.5 °C and an "off" signal at 26.5 °C.
This parameter is only available if "2-step control" is set as the control type.
Invert cooling
Options: - Yes
- No
"Invert cooling" is used to adjust the direction of control action of the
control value to "de-energised open" or "de-energised closed" valves.
This parameter is only available if "2-step control" is set as the control type.
