12.1.33 RTC - Fan manual (heating)
Name
RTC: Fan manual
RTC: Fan manual (master)
RTC: Fan manual (slave)
Using the 1-bit communication object, a fan coil actuator can be placed in manual fan mode or
returned to automatic fan mode. In the automatic fan mode of the fan coil actuator, the fan's
rotational speed is defined in the fan coil actuator using the control value. In manual fan
operation, the user of the RTC can set the fan's rotational speed as needed. This setting will
remain active until it is reset. The fan speed level 0 is an exception: to avoid damage to the
building, automatic mode is activated again 18 hours after fan speed level 0 is selected.
If a fain coil regulator is set for both operating modes of heating and cooling and an own
generating device is set for both operating modes, this communication object then operates
jointly with fan coil regulator heating.
Notice
When the master/slave operation is activated, the object "RTC: Fan manual
(master)" of the master device must be connected with object "RTC: Fan manual
(slave)" of the slave device.
12.1.34 RTC - Fan speed level (heating)
Name
RTC: Fan speed level
RTC: Fan speed level (master)
RTC: Fan speed level (slave)
The fan speed level in the fan coil actuator is selected via the 8-bit communication object.
The fan speed levels are sent to the bus as percentage values. Example 5-stage fan: The level
value 1 is output as 20%, and 5 is output as 100%. The setting of the levels can also be made
optionally as counter values, in this example 0..5.
If a fain coil regulator is set for both operating modes of heating and cooling and an own
generating device is set for both operating modes, this communication object then operates
jointly with fan coil regulator heating.
Notice
When the master/slave operation is activated, the object "RTC fan speed level
(master)" of the master device must be connected with object "RTC: Fan speed
level (slave)" of the slave device.
