Saving mode (RDF410.21)
•Optional with infrared remote control and LCD backlight (RDF310.21, RDF410.21)
Controller
Temperature control The controller acquires the room temperature via its built-in sensor and maintains the
setpoint by delivering 2-position valve control commands or compressor output com-
mands.
The switching differential is 2 K in heating mode and 1 K in cooling mode (adjustable
via parameters P08 and P09).
Display The display shows the acquired room temperature or the setpoint of the current operat-
ing mode. This can be selected via parameter P18. Factory setting is display of the
current room temperature.
The heating and cooling symbols on the display show the status of the fan coil.
This means that the symbols are also shown while the controller operates in the neutral
zone.
If required, room temperature and setpoint can also be displayed in °F in place of °C by
changing parameter P17.

Operating modes
The following operating modes are available:
Normal operation In Normal operation, the controller maintains the setpoint, which can be adjusted via
the + - buttons. The fan can be set to automatic or manual fan speed: Low, medium or
high.
The setpoint setting range can be limited to a minimum (P05) and maximum (P06). This
helps prevent the waste of energy, thus saving costs.
Tip!
Standby When the controller is in Standby mode , the relevant setpoints of heating or cooling
are maintained. These setpoints can be adjusted via control parameters P03 and P04.
Factory setting of both setpoints is OFF, which means that the controller is not acti-
vated when in Standby mode.
In Auto Timer mode AUTO, the controller will automatically change over between Normal
operation and Energy Saving mode according to the 8 preprogrammed timers. The
display shows the Auto Timer mode symbol AUTO and the symbol of the operating mode
currently maintained, either Normal operation or Energy Saving mode .
The setpoints of Energy Saving mode can be adjusted via control parameters
P01 and P02.
The default fan speed in Auto Timer mode is automatic fan.
Auto Timer mode AUTO
(only with RDF410.21)
Energy Saving mode
To avoid damage due to moisture in very warm and humid climatic zones resulting from
lack of air circulation in Energy Saving mode, the fan can be kept running all the time
(e.g. in apartments or shops during unoccupied periods), when setting parameter P20
“ON in dead zone”. In this case, the fan keeps running at minimum fan speed 1.

(factory setting 1 minute, adjustable by parameter P15)
Heating / cooling
mode When pressing the heating / cooling changeover button , the controller will change
from heating to cooling, or vice versa.
If the controller was set to ”Cooling only” or ”Heating only”,changeover will not be pos-
sible (parameter P22, factory setting ”manual changeover”), instead NOP will flash on
the display, indicating continuous cooling or heating is set respectively.
Minimum output
on time / off time Y11 The minimum output on time and off time of Y11 can be adjusted from 1…10 minutes
via parameters P15 and P16. Factory setting is 1 minute. In this case, any readjustment
of the setpoint or of heating / cooling mode changeover will be used immediately for
computing the output status and output Y11 may not hold the minimum on / off time of
1 minute.
If parameter P15 or P16 is set to a level above 1 minute, the minimum on / off time of
Y11 will be maintained as set, even if the setpoint or changeover mode has been read-
justed.
Fan operation
The fan operates either in automatic mode or at the selected speed when using manual
mode. In automatic mode, the fan speed depends on the setpoint and the current room
temperature. When the room temperature reaches the setpoint, the control valve will
close and the fan either remains in fan speed 1 or switches off (parameter P21, factory
setting: fan speed 1 in dead zone).
In “Temperature-dependent” fan control the fan switches off (see diagram below). The
individual switching differentials of the fan speeds can be adjusted via control parame-
ters P08 – P13.

If desired, fan control can be set to ”Temperature-independent”, which means that ven-
tilation is always on, even within the dead zone, using at least fan speed 1. This can be
selected individually for Normal operation using parameter P21 and for Energy Saving
mode using parameter P20 (only for RDF410…; also refer to “Avoiding damage due to
moisture”).
Ventilation
always on
In automatic mode, a dwelling time of 2 minutes (factory setting) is active. The fan
maintains that speed for at least 2 minutes before it switches to the next speed. This
dwelling time can be adjusted from 1…5 minutes using parameter P14.
Dwelling time
Fan start Whenever the fan starts from standstill, it starts with speed 3 for 1 second in order to
guarantee a safe fan motor start (to overcome inertia and friction)

Error handling
When the room temperature is out of the measuring range, which means above 49 °C
or below 0 °C, the display shows the limiting temperature in flashing figures, e.g. “0 °C”
or “49 °C”.
If the current setpoint is not OFF (see parameters 1-4) and the controller is in heating
mode, and the temperature is below 0 °C, output Y11 will be energized. In all other
cases, output Y11 will be deenergized. When the temperature returns to the measuring
range, the controller will resume Normal operation.

Mounting and installation
The room controller can be mounted on a recessed rectangular conduit box with fixing
centres of 60.3mm. The mounting location on a wall should not be in niches or book-
shelves, not behind curtains, above or near heat sources and not exposed to direct
solar radiation. Mounting height is about 1.5 m above the floor.
Also refer to the Mounting Instructions B3067 enclosed with the controller.
Wiring
•Wiring, fuse and earthing must be installed in compliance with local regulations.
•The cables to the controller, fan and valves carry AC 230 V mains voltage and must
be appropriate sized
•Only valves rated for AC 230 V may be used
•The AC 230 V mains supply line must have an external fuse or circuit breaker with a
rated current of no more than 10 A
After applying power, the controller makes a reset during which all LCD segments flash,
indicating that the reset has been correctly made. This takes about 3 seconds. Then,
the controller is ready for commissioning by qualified HVAC staff. The control parame-
ters of the controller can be set to ensure optimum performance of the whole system
(also refer to “Setting the control parameters”).
Commissioning
•Depending on the application, the heating / cooling mode must be set via parameter
P22. Factory setting is “Manual heat/cool changeover”. When using in ”Cooling
only” or “Heating only”, P22 must be set accordingly.
Heating / cooling mode
•If the controller is used in conjunction with a compressor, the minimum output on
time (parameter P15) and off time (parameter P16) of Y11 must be adjusted in order
not to harm the life time of the compressor
Compressor-based
application
•If the room temperature displayed by the controller dos not accord with the room
temperature effectively measured, the temperature sensor can be recalibrated. In
that case, parameter P07 must be changed
Calibrating the sensor
•For comfort and energy saving reasons, it is suggested to review the setpoints and
setpoint ranges (parameters P01…P06) and, if necessary, to change them
accordingly
Setpoint and range

Disposal
The controller includes electrical and electronic components and must not be disposed
of as domestic waste.
Current local legislation must be observed.
