The fan operates either in automatic mode or at the selected speed when using manual mode. You can either rely on
the factory settings or make adjustments that suit your individual needs.

Are your rooms too warm or too cold?
+
Only applicable in normal operation.
Pressing
or allows you to increase or decrease the current room temperature setpoint for normal operation in
increments of 0.5 °C. The maximum setting range is from 5...40 °C, unless it is limited by parameters P05 and P06.
Do you want to set your controller to standby?
Press the
button several times until the display shows the
symbol to indicate that standby is selected.
In standby
, the controller maintains the adjusted lower setpoint of
heating (parameter P03) or the higher setpoint of cooling
(parameter P04).
Important:
If the setpoint of standby is set to
OFF (factory setting), this means
the controller will not be active in standby.
Risk of frost!
Do you want to change the fan mode?
AUTO
Press the button until you have selected the desired fan
mode.
In automatic mode, the fan speed is automatically selected by the
controller and depends on the setpoint and the actual room
temperature. When the room temperature has reached the setpoint,
the fan switches off.
In manual mode the fan operates independently and always runs at
the same speed: Low, Medium or High.
The actual fan speed is indicated by the number of fan symbols.
Low fan speed
Medium fan speed
High fan speed
Do you want to change from heating to cooling mode?
/
With the RDF110, the changeover between cooling and heating is
done either automatically by a heating / cooling changeover sensor
or a remote changeover switch. If the controller is commissioned
cooling only or heating only, no changeover is possible (see para-
meter P22: factory setting
cooling only).
With the RDF110.2, when pressing the
button, the controller
changes from heating to cooling or vice versa.
Do you want to change to Energy saving mode?
/
/
With the RDF110 only, a changeover from normal operation or
standby to energy saving mode takes place automatically via an
external contact such as window switch, key card switch etc. In
energy saving mode the AUTO fan speed is active.
Energy saving mode
+
If you want to change the factory-set temperature setpoints (16 °C
for heating and 28 °C for cooling), follow the procedure “Changing
the control parameters”.
Important:
The setpoint of energy saving mode can be set to
OFF. This means
that the controller is not active in energy saving mode and symbol
AUTO will not appear.
Risk of frost!
