Type of control value
Options: - Continuous (1 Byte)
- Switching (1 Bit)
The additional stage for cooling can transmit a 1-bit or 1-byte sized
control value. If "Switching 1-Bit" is selected, the additional stage controls
a switching control (1-bit) via a 1-bit communication object, e.g., a
thermoelectric actuator that controls a switch actuator. If "Continuous 1-Bit"
is selected, the additional stage provides continuous control (1-byte) via a 1-
byte communication object, e.g., an actuator with integrated pulse width
modulation.
This parameter is only available if the "Cooling" or "Heat and cool" control
functions are used.
Invert control value
Options: - Yes
- No
The control value is adjusted to "de-energised open" or "de-energised
closed" valves via the direction of control action of the controller.
This parameter is only available if the "Cooling" or "Heat and cool" control
functions are used.
