The parameter "Manual fan stage send has the following code" can be used to enable a 1-byte object or three 1-bit
objects.
The selected fan stage can be sent via the 1-byte object as a counter value from 0 to 3 (0=no manual switch) or the
continuous value from 0 to 100 %.
The continuous values for output are specified by the settings in the threshold values for the specific stage.
When 1-bit values are selected, a 1-bit communication object is available for every fan stage. If the fan stage is
manually switched, an OB telegram is sent via the corresponding object. An OFF telegram is sent if the manual
switch is cancelled.
Send cycle time of actuator in s (0 ... 65535) sec (0 - disab)
Options:
- 1
- 2
- ...
- 120
- ...
- 65,535
If the "Status byte operation" object is enabled and connected to the corresponding communication object of the fan
coil actuator, the ambient temperature controller expects a cyclic transmission of the operating status of the linked
fan coil actuator. If a message from the actuator is not sent within the monitoring time "Send cycle time of actuator
in s" at least once, the ambient temperature controller automatically shows the fault display. The cycle time of the
actuator should therefore be set to ensure that a telegram is sent at least twice during "Send cycle time of actuator
in s (0 ... 65535) sec (0 - disab)".
Stage of fan after reset
Options:
- Off
- Stage 1
- Level 2
- Level 3
- Automatic
The parameter "Stage of fan after reset and after off" is used to prevent undefined states after a reset or switching off
the ambient temperature controller. It specifies whether the fan switches on the first, second or third stage, switches
off or switches to automatic mode.
Note:
Automatic mode means that the fan coil actuator switches the fan stages based on the received 1-byte control value.
