7 . COMMUNICATION OBJECTS (continued)
7 .10 "Fan Coil" parameter (continued)
7 .10 .1 "Fan" parameter (continued)
Fan speed on bus voltage recovery
unchanged
*off
1
2
3
Using this parameter, the fan behavior is defined after bus voltage
recovery is set.
Enable forced operation
yes
*no
This parameter is used to enable fan-forced operation.
Forced operation on object value
0
*1
This parameter is selected which value is activated the forced
operation.
Limitation on forced operation
3, 2, 1, OFF
*unchanged
…
This parameter is selected the forced operation behavior.
Enable automatic operation
*yes
no
This parameter can be enabled the automatic control. Automatic
control meaning is limited reaction according to “
Control input
”.
Enable direct operation
yes
*no
This parameter can be enabled the direct control. Direct control
meaning is control via direct communication object.
Starting characteristic of fan
yes
*no
This parameter enables the fan to start from the OFF state with
a defined fan speed. The fan can be switched on temporarily to
a defined switch-on level. This switch-on level can be any of the
available fan levels.
Switch on to switch-on level
1
2
*3
This switch-on level can be any of the available fan levels.
Minimum dwell period in switch on in s
[1…65535]
1…
*5
…65535
The fan thus remains in the switch-on level until the set dwell time has
elapsed.
7 . COMMUNICATION OBJECTS (continued)
7 .10 "Fan Coil" parameter (continued)
7 .10 .2 "A/B1 - Status Message" parameter
Enable communication object “Status fan
speed x” 1 bit
yes
*no
The data format for the fan level feedback is defined as 1 bit. Separate
objects are defined separately for each fan level. When the fan level is
changed, the actuator updates and transmits only the object values
that change.
Meaning
*current fan speed
required fan speed
Current fan speed:
The fan is actual operating state.
Required fan speed:
The fan desired fan state. E.g. when the
translation and dwell times are completed.
Fan operation mode
*no
after a change
after request
after change or request
This parameter defines the object send type.
Enable communication object “Status fan
speed” 1 byte
yes
*no
The data format for the fan level feedback is defined as 1 byte.
Meaning
*current fan speed
required fan speed
Current fan speed:
The fan is actual operating state.
Required fan speed:
The fan desired fan state. E.g. when the
translation and dwell times are completed.
Send object type
*no
after a change
after request
after change or request
This parameter defines the object send type.
Enable communication object “Status fan
ON/OFF” 1 bit
yes
*no
This ON telegram acts on a main switch that has to be switched on.
Send object type
*no
after a change
after request
after change or request
This parameter defines the object send type.
Enable communication object “Status
automatic” 1 bit
yes
*no
This parameter is enabled the communication object “
Status
automatic
”.
Send object type
*no
after a change
after request
after change or request
This parameter defines the object send type.
