8.2.3 Overriding the damper actuator
For test purposes, the damper actuator can be overridden via the following
communication objects:
Damper override (Input communication object)
Flags
Type Receive timeout Value
R
W
K
T
U
0 1 1 0 0 8.010
DPT_Percent_V16
no 0...100% 0 = 0%
+100 = +100%
+32767 = invalid
Before the damper actuator can be overridden, “Test” mode must be activated via the
communication object Application mode (see page 145).
The actuator is operated in accordance with the settings shown below:
Heating
value
Cooling
value

The full travel of the damper is 0…100%.
The actuator moves to the position defined by the
heating value.
8.3 Fan coils with an electric reheater
In addition to controlling heating and/or cooling valves, some applications also provide
an output for the control of an electric heating coil. This is then operated as a reheater,
i.e. it only comes into operation when the heating valve is fully open.
• RXB2...: Relay with 2-position / PWM action
• RXB39.1: DC 0...10 V control plus enabling / disabling via a volt-free relay contact.
• With motorized actuators, the electric reheater is only enabled when the heating
valve is fully open.
• In the case of thermal actuators, the electric reheater is not enabled until the thermal
actuator has been operated at maximum flow (100%) for at least 2 minutes.
• RXB2... : The switching differential is fixed at 1.0 K.
• RXB39.1: If the electric reheater is active, the fan is driven to a speed of min. 10%.
