• Optional with infrared remote control (only with RDF210…/IR)
Controller
Temperature control
Display
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 commands. With the RDF210, an external room temperature sensor (QAA32) or external
return air temperature sensor (QAH11.1) can be used instead.
The switching differential is 2 K in heating mode and 1 K in cooling mode (adjustable
via parameters P08 and P09).
The display shows the acquired room / return air temperature or the setpoint of the
current operating 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.

The following operating modes are available:
Normal operation
Tip!
Auto Timer mode
Energy Saving mode
Standby
Avoiding damage
due to moisture
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.
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
AUTO
display shows the Auto Timer mode symbol
currently maintained, either Normal operation
and the symbol of the operating mode
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.
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 activated when in Standby 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.

Fan operation
With the RDF210, the changeover between cooling and heating takes place either
automatically via a heating / cooling changeover sensor or a remote changeover
switch. If the controller was set to ”Cooling only” or ”Heating only”, changeover will not
be possible (parameter P22, factory setting ”Cooling only”).
With the RDF210.2, when pressing the heating / cooling changeover button
, the
controller will change from heating to cooling, or vice versa.
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 readjusted.
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 switch off: Temperature-dependent fan control (see diagram below).
The individual switching differentials of the fan speeds can be adjusted via control parameters P08 – P13.

always on
If desired, fan control can be set to ”Temperature-independent”, which means that ventilation 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 (also refer to “Avoiding damage due to moisture”).
Dwelling time
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.

External sensor input B1-M
Automatic heating /
cooling changeover
Remote heating /
cooling changeover
With the RDF210, a return air / external room temperature sensor or heating / cooling
changeover sensor can be connected to terminal B1-M. The function of this sensor
input is determined by parameter P22.
Sensor input B1-M is not galvanically separated from the AC 230 V mains supply.
Therefore, only a cable temperature sensor and wiring with sufficient insulation must be
used.
When P22 is set to “Automatic H/C changeover”, the sensor input acts to ensure automatic heating / cooling changeover. The water temperature acquired by the changeover
sensor (QAH11.1 + ARG86.3) is used to switch from heating to cooling mode, or vice
versa. When the water temperature lies above 28 °C (parameter P24), the controller
switches to heating mode; below 16 °C (parameter P23), it switches to cooling mode. If,
immediately after switching on, the water temperature lies between the 2 changeover
points, the controller will start in heating mode. The water temperature is acquired at
30-second intervals and the operating state is updated.

When parameter P22 is set to “Cooling only” or “Heating only”, sensor input B1-M can
be used to connect an external room temperature (QAA32) or a return air temperature
sensor (QAH11.1). Changeover is automatic if a sensor is detected at the sensor input.
With parameter P98 (diagnostic value), the sensor status can be checked.

Infrared remote control
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.
In case of an external sensor failure (short-circuit or open-circuit), the controller will
immediately switch back to the internal sensor to ensure control.
Should both the external and internal sensor fail, the display will flash “Err” to call the
user‘s attention.
The RDF210/IR and RDF210.2/IR have an infrared receiver built in. Together with the
IRA210 infrared remote control, the following operations can be performed from a remote location:
• Selection of operating mode: Standby, Normal operation or Auto Timer
• Adjustment of setpoint in Normal operation
• Selection of fan mode: Automatic or manual fan speed
Using parameter P25, infrared remote control can be disabled.
Control parameters
Parameter settings
With the RDF210 and RDF210.2, a number of control parameters can be readjusted to

Mounting and installation
Wiring
The room controller can be mounted on a wall or inside the fan coil unit. The mounting
location on a wall should not be in niches or bookshelves, 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.
The controller can be fitted on a recessed conduit box.
When using a heating / cooling changeover sensor, then, before fitting the sensor,
thermal conductive paste must be applied to the location on the pipe where the sensor
is placed.
Also refer to the Mounting Instructions B3058 enclosed with the controller.

Diagnostic values
• Wiring, fuse and earthing must be installed in compliance with local regulations. It
must be made certain that safety extra low-voltage lines (SELV circuit) are clearly
separated from AC 230 V mains voltage cable
• The cables to the controller, external sensor, fan and valves carry AC 230 V mains
voltage and must be appropriate sized
• Only sensors and 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
• Maximum 10 changeover contact inputs B1-M can be connected in parallel if an
external switch is used in place of a changeover sensor. The switch must be suited
for AC 230 V. The cable length must not exceed 80 m overall
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 parameters of the controller can be set to ensure optimum performance of the whole system
(also refer to “Setting the control parameters”).
• Only with RDF210: Depending on the application, the heating / cooling mode must
be set via parameter P22. Factory setting is “Cooling only”. When using the ”Automatic heating / cooling changeover” function, P22 must be set to “Automatic H/C
changeover”.
Note: When P22 is set to “Automatic H/C changeover”, the integrated sensor is
used for acquiring the room temperature
• 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
• 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
• 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
• Only with RDF210: Parameters P98 and P99 are diagnostic values and help check
the system. With P98, the status of the active temperature sensor is shown and,
with P99, the status of the heating / cooling changeover sensor
