Fan coil auto/manual
No.
Function

Auto on/off
If a fan coil actuator is tripped by the ambient temperature controller, the individual fan stages
are typically switched automatically by the room thermostat. However, users can select
a stage manually. When the stage is specified manually, the 1-bit communication object
triggers an ON telegram and when manual mode is deactivated, an OFF telegram is sent.
This enables you to notify a second control unit that a stage has been set manually.
The 1-bit object can also receive and analyse telegrams sent from other control points.
This data item forms the 1-bit KNX object and can be sent and received. When switching
to manual operation and sending a fan stage via the display, manual mode is enabled.
Automatic mode is re-enabled with this data item after automatic return after a
parametrisable time. For example, if an automatic return is not to be parametrised,
the RTR can be reset externally to the controlling operation via this object.
Note: the coding of this object is matched to ABB actuators. A link to other manufacturers
may make it necessary to use the alternative object „manual switching on/off".

1: the fan stage is set to „auto"

The object is visible alternatively to 1-bit objects 34-36.
The device sets the fan stage actuator to manual mode with this object.
The object has two possible codings, which can be set alternately in the parameters.
Coding 1: 1 byte continuous value (0...100%)
Coding 2: 1 byte counter value, value range 0...3

Fan level manual control 1
This 1-bit communication object can be used to send an ON telegram, if the second fan stage
to be switched on. An OFF telegram is sent, if the first fan stage is no longer to be switched on.
This data item forms the 1-bit KNX object and can be sent and received.
24
Fan level manual control 2
This 1-bit communication object can be used to send an ON telegram, if the second fan stage
is to be switched on. An OFF telegram is sent, if the second fan stage is no longer to be switched on.
This data item forms the 1-bit KNX object and can be sent and received.
