This 1-bit communication object is used to place the controller in the condensation alarm
mode.
This causes the current setpoint value to be set to the heat protection setpoint value in
order to keep the structure from being damage by an overflowing condensation container.
12.35.27 Fan coil setting - Object no
Object name
Fan coil manual
Fan coil manual – (Master)
Fan coil manual – (Slave)
Item 2: If fan coil manual is active in the master/slave mode, the fan coil manual (slave)
object must be connected to this object.
Item 3: If fan coil manual is active in the master/slave mode, the fan coil manual (master)
object must be connected to this object.
Using this 1-bit communication object, a fan coil actuator can be place 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 room temperature controller 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 select.
12.35.28 Fan coil setting – Fan speed level – Fan coil step - Object no
Object name
Fan coil step
Fan coil step (Master)
Item 2: If fan coil step is active in the master/slave mode, the fan coil step (slave) object
must be connected to this object.
The fan speed level in the fan coil actuator is select via the 1-byte communication object.
Whether the fan speed level information is transmitted in manual or also in automatic fan
speed level mode can be set. The formats that can be selected for the 1-byte
communication object are the fan speed level (0..5) or a percentage value (0..100%)
which is calculated back to a fan speed level in the fan coil actuator.
