Operating Instructions
RDF300…, RDF340…,
RDU340…
RDF/RDU… – the temperature controller that allows you to set the ideal room temperature you want. The controller
provides comfort mode, energy saving mode and standby. 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?
+ -
Pressing + or - allows you to increase or decrease the current room temperature setpoint for comfort mode.
The maximum setting range is from 5...40 °C, unless it is limited by parameters P09 and P10.
Do you want to change from heating to cooling mode?
/
The changeover between cooling and heating is done either automatically by a
heating / cooling changeover sensor or a remote changeover switch, or manually
by pressing the operating mode button
. If the controller is configured cooling
only or heating only, no changeover is possible (see parameter P01)
By automatic changeover or continuous heating/cooling:
Display shows that heating valve is open
Display shows that cooling valve is open
By manual changeover:
Display shows that controller is in heating mode
Display shows that controller is in cooling mode
Do you want to change the fan mode?
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 remains in fan speed low (factory
setting)
In manual mode the fan operates independently and always runs at the same
speed: Low, medium or high.
Low fan speed
Medium fan speed
High fan speed
By a single-speed fan, the mode can be changed between
and .
Do you want to set your controller to standby?
Press the operating mode button several times until the display shows the
symbol to indicate that standby is selected.
In standby
, only frost protection is active (factory setting = 8˚C), unless your
HVAC installer has adjusted the factory settings.
Changes by installer Frost protection: ........... ˚C
Heat protection: ........... ˚C
Do you want to change to Energy saving mode?
The controller can be set in energy saving mode either via pressing the operating
mode button
if enabled (see parameter P02), or via an external contact such
as window switch, key card switch etc.
If the external contact is activated the controller changes from comfort mode or
standby to energy saving mode. Any operation by the user has no influence.
In energy saving mode the automatic fan speed is active.
Note: If the controller is configured for manual heating / cooling changeover, the
Energy saving mode can not be selected via operating mode button
.

Commissioning (by qualified HVAC installer)
To adapt the controller to your system and optimize the control performance, a number of
control parameters can be adjusted. This can also be made during operation without
opening the controller.
Control sequence
Recalibrating the sensor
Energy saving mode
If you want to change the factory-set temperature setpoints (15 °C for heating
and 30 °C for cooling), the parameter P11 and P12 need to be adjusted.
Important: The setpoint of energy saving mode can be set to OFF; this
means that the controller is then not active! Risk of frost, i.e. no protective
heating or cooling function.
Control parameter
If you want to change the control parameters, proceed as follows:
+ / -
+ / -
+ / -
+ / -
1. Set the controller to standby
2. Press - and + simultaneously for a minimum of 3 seconds.
Release them and, within 2 seconds, press the + again for 3 seconds. The display will show “P01”.
3. Select the required parameter by repeatedly pressing the + or – button.
4. Press + and – simultaneously, the current value of the selected parameter starts to flash, which can be
changed by repeatedly pressing + or -.
5. By pressing + and - simultaneously again the next parameter will be displayed.
6. If you wish to display and change additional parameters, repeat steps 3 through 5.
7. 10 seconds after the last display or setting, all changes are stored and the controller will leave parameter enter
mode.
Please record all changes you make! (all temperature settings can be made in increments of 0.5 K)
If the keypad lock function is enabled by parameter P14, then pressing 7
seconds on the operating mode button
, the keypad will be locked or
unlocked respectively.
If “Auto lock” is configured, then the controller will automatically lock the
keypad after 30 seconds of the last adjustment.
FIL
This message reminds you to clean the filter on your HVAC equipment.
It will appear after …………….….. “fan operating hours” and disappear
when the controller is set to standby (
). This reminder must be configured
by your HVAC installer.
AL1
AL2
This alarm message tells you an external alarm has occurred:
AL1 :……………………………..….
AL2 :………………………………….
The alarms are configured by your HVAC installer
The controller can be used in systems either for heating only or cooling only,
manually selection of heating or cooling, or automatic heating / cooling
changeover. Depending on the selected application, the relevant modes are
available and can be adjusted by commissioning parameter P01 if needed.
The factory setting for 2-pipe and single duct application is “Cooling only”,
and for 4 pipe application “Heating and Cooling”
If the room temperature displayed by the controller does not agree with the
temperature effectively measured, the temperature sensor can be
recalibrated. With parameter P05 the temperature can be adjusted by + or –
0.5 °C up to a maximum of + / - 3 °C.
