Functions
4.1
Temperature control
The setting of he control parameters (P01 etc., mentioned throughout the
document) is described in section 4.14.
The controller acquires the room temperature via built-in sensor, external room
temperature sensor (QAA32), or external return air temperature sensor (QAH11.1),
and maintains the setpoint by issuing actuator control commands to heating and/or
cooling equipment. The following control outputs are available depending on the
controller type:
 On/off control (2-position) with RDF300…/RDF400… / RDF600…
 Modulating PI control with 3-position control output on RDF300…/RDF400… /
RDF600…
 Modulating PI control with DC 0..10 V control output on RDF340
The switching differential or proportional band is 2 K for heating mode and 1 K for
cooling mode (adjustable via parameters P30 and P31).
The integral action time for continuous PI control is 5 minutes (adjustable via
parameter P35).
Display
/
Concurrent display of
°C and °F
The display shows the acquired room temperature or the setpoint for the current
operating mode, selectable via parameter P06. The factory setting displays the
current room temperature.
Use parameter P04 to display the room temperature or setpoint in °F rather than
°C as needed.
If the controller is used in a system with manual heating/cooling changeover
(P01=2), the heating and cooling
symbols on the display show the fan coil or
terminal unit status. Thus, the symbols are displayed even when the controller
operates in the neutral zone. For all other cases, the heating and cooling
symbols are displayed when the heating or cooling output is energized.
Concurrent display of the current temperature or setpoint in °C and in °F
(parameter P07) is possible on the controller without weekly time program.

4.2
Operating modes
Select the controller's operating mode via operating mode button on the controller or operating mode input (e.g. keycard occupancy sensor, when X1 or X2 set to
3 (P38, P40)). A corresponding setpoint is used to maintain the room temperature
at the desired level depending on the active operating mode. The following
operating modes are available:
Comfort mode
In Comfort mode, 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.
Economy
Economy mode helps save energy. Select it by pressing the operating mode button
if parameter P02 is set accordingly, or if the external operating mode switchover
contact is active (e.g. window contact).
Note
If the external operating mode switchover contact is active, user operations are
ineffective and “OFF” is displayed. Control will then be according to Economy
setpoints (P11 and P12).
Protection mode
In Protection mode, the system is
– protected against frost (factory setting 8°C, can be disabled or changed via P65)
– protected against overheating (factory setting OFF, can be enabled or changed
via P66)
Auto Timer mode
(only with RDF400... ,
RDF600T)
AUTO
In Auto Timer mode , the controller automatically changes from Comfort to
Economy mode as per the 8 preprogrammed timers. The display shows the Auto
AUTO
Timer mode symbol
along with the symbol for the current operating mode
(Comfort
or Economy ).
Automatic is the default fan speed in Auto Timer mode.

Room temperature setpoints
Comfort mode
The setpoint in Comfort mode can be adjusted via the +/- buttons.
Setpoint limitation
For energy saving purposes, the setpoint adjusting range can be limited to
minimum (P09) and maximum (P10).
P09 < P10
 If the minimum limit P09 is set lower than the maximum limit P10, both heating
and cooling are adjustable between these two limits.
P09 ≥ P10
 For heating or cooling applications (e.g. 2-pipe)
– The setting range in cooling mode is from P09…40° instead of 5…40°
– The setting range in heating mode is from 5…P10° instead of 5…40°
 For heating and cooling applications (e.g. 4-pipe)
– P09 is the setpoint for cooling and P10 the setpoint for heating;
– the setpoint can no longer be adjusted via the +/- buttons

Cooling settable 25…40°C
Heating settable 5…21°C
Temporary setpoint
If the “Temporary setpoint function” is enabled via parameter P69, the setpoint
adjusted via the +/- buttons is set back to the Comfort basic setpoint when the
operating mode changes.
The factory setting for the Comfort basic setpoint is 21 °C and can be changed via
parameter P08.
Economy mode
Use control parameters P11 and P12 to adjust the Economy mode setpoints.
The heating setpoint is factory-set to 15 °C and to 30 °C for cooling.
Protection mode
Caution
Use control parameters P65 and P66 to adjust the Protection mode setpoints.
The heating setpoint is factory-set to 8 °C (frost protection) and to OFF for cooling.
If a setpoint is set to OFF (P65, P66), the controller does not maintain the setpoint
in the corresponding mode (heating or cooling).
This means no protective heating or cooling function and thus risk of frost in the
heating mode or risk of overheat in cooling mode!

Water-based fan coil
application
Use with one or two valves for heating and cooling, heating/cooling with
changeover, heating only, or cooling only.
Compressor-based
application
Use with one 1-stage compressor for heating and cooling, or cooling only, or
heating only.
Universal applications
Thanks to a flexible fan control, the RDF3xx / RDF4xx can also be used in
universal applications, e.g. fan coil-based cooling and floor heating, or chilled
ceiling and electrical heater etc. See also section 4.8 “Fan control”.
4.5
Automatic H/C
changeover
Additional features
The water temperature acquired by the changeover sensor (QAH11.1 + ARG86.3)
is used to change over from heating to cooling mode and vice-versa. When the
water temperature is above 28 °C (parameter P37), the controller changes over to
heating mode, and to cooling mode when below 16 °C (parameter P36). If the
water temperature is between the 2 changeover points immediately after power up,
the controller starts in previous mode.
The water temperature is acquired at 30-second intervals and the operating state is
updated accordingly.

The controller acquires the room temperature via built-in sensor, external room
temperature sensor (QAA32), or external return air temperature sensor (QAH11.1)
connected to multifunctional input X1 or X2.
Inputs X1 or X2 need to be commissioned accordingly. See section 4.9 “Multifunctional input”.

Functions
CE1P3076.en
2012-10-02
Purge function
The changeover sensor is tasked with initiating changeover from heating to cooling
mode based on the acquired water temperature. We recommend activating the
purge function (parameter P50) with 2-port valves. This function ensures correct
acquisition of the medium temperature even if the 2-port valve is closed for an
extended period of time. The valve is then opened for 1 to 5 minutes (adjustable) at
2-hour intervals during off-hours.
Caution
The purge function (parameter P50) must be disabled if the controller is to be used
in compressor-based applications.
Avoid damage from
moisture
In very warm and humid climates, the fan can be run periodically or continuously at
a low fan speed (e.g. in empty apartments or shops) in Economy mode by setting
parameter P61 to avoid damage from moisture due to a lack of air circulation. See
also section 4.8 “Fan control”, under “Fan kick function”.
Minimum output
on-time/off-time
Limit the on/off switching cycle to protect the compressor and reduce wear and
tear. The minimum output on-time and off-time for 2-position control output
Y11/Y21 can be adjusted from 1 to 20 minutes via parameters P48 and P49.
The factory setting is 1 minute
Readjusting the setpoint or heating/cooling mode changeover immediately results
in calculation of the output status; controller output Y11/Y21 may not hold the min.
1-minute on/off time.
If parameter P48 or P49 is set to above 1 minute, the min. on/off time for Y11 is
maintained as set, even if setpoint or changeover mode is readjusted.
This function is only available for on/off control.
Floor heating
limitation function
The floor heating limitation function is a part of the floor heating application (heating
with fan disabled).
The floor temperature sensor, connected to multifunctional input X1 or X2,
measures the floor temperature. If the temperature exceeds the parameterized limit

Dewpoint monitoring is essential to prevent condensation on the chilled ceiling
(cooling with fan disabled). It helps to avoid associated damage to the building.
A dewpoint sensor with a voltage-free contact is connected to multifunctional input
X1 or X2. If there is condensation, the cooling valve is fully closed until no more
condensation is detected, and the cooling output is disabled temporarily.
The condensation symbol is displayed during temporary override.
Input X1 or X2 must be commissioned accordingly.

4.6.2
2-pipe fan coil unit with electrical heater
Heating or cooling with
electric heater
In 2-pipe applications with electrical heater, the controller controls a valve in
heating/cooling mode with changeover, heating only mode, or cooling only mode
plus auxiliary electrical heater. Cooling only is factory set (P01=1) with enabled
electrical heater (P13).
Electrical heating,
active in cooling mode
In cooling mode, the valve receives an OPEN command if the acquired
temperature is above the setpoint. The electrical heater receives an ON command
if the acquired room temperature drops below “setpoint” – “dead zone” (=“setpoint
for electrical heater”) while the electrical heater is enabled (parameter P13).
Note: “Setpoint for electrical heater” is limited by parameter “Maximum heating
setpoint” (P10).
Electrical heating in
heating mode
Electrical heating, and
manual changeover
In heating mode, the valve receives an OPEN command if the acquired
temperature is below the setpoint. The electric heater is used as additional heating
source when the heating energy controlled by the valve is insufficient. The
electrical heater receives an ON command, if the temperature is below “setpoint” –
“setpoint differential” (=setpoint for electrical heater).
The electrical heater is active in heating mode only and the control output for the
valve is permanently disabled when manual changeover is selected (P01=2).
Digital input “Enable
electrical heater”
Remote enabling/disabling of the electrical heater is possible via digital input X1/X2
for tariff regulations, energy saving etc.
Input X1 or X2 must be commissioned accordingly. See section 4.9 “Multifunctional
input”.

4-pipe fan coil unit
In 4-pipe applications, the controller controls two valves in heating and cooling
mode, heating/cooling mode by manual selection, or heating and cooling mode
with changeover. Heating and cooling mode (P01=4) is factory set.
4-pipe application with
manual selection
The heating or cooling output can be released via operating mode selector button if
parameter P01 is set to manual (P01=2).
“Main and Secondary”
application (4-pipe
with changeover)
The heating and cooling output is swapped per the sensor input status (see
automatic heating and cooling changeover sensor), if parameter P01 is set to
changeover (P01=3). This mode is used for “Main and Secondary” application,
which equates to a 4-pipe fan coil unit system with different capacity for heating
and cooling coils. The water circuit is changed to optimize the energy exchange
depending on the season (summer/winter).

The valve or compressor receives the OPEN/ON command via control output Y11
or Y21:
1. When the acquired room temperature is below the setpoint (heating mode) or
above the setpoint (cooling mode).
2. When control outputs Y11/Y21 were not energized for more than the “Minimum
output off time” (factory setting 1 minute, adjustable via parameter P48).
The valve or compressor receives the CLOSE/OFF command via control output
Y11 or Y21:
1. When the acquired room temperature is above the setpoint (heating mode) or
below the setpoint (cooling mode).
2. When control outputs Y11/Y21 were energized for more than the “Minimum
output on time”; (factory setting 1 minute, adjustable via parameter P49).
3-position control
signal
Output Y11 provides the OPEN command, and Y21 the CLOSE command to the 3position actuator. The factory setting for the runtime is 150 seconds (adjustable via
parameter P44 from 50…240 seconds).
1. When the controller gets powered up, a closing command for the actuator
runtime + 150% is provided to ensure that the actuator fully closes and
synchronizes to the control algorithm. (RDF3..., 4...: SW < 3.1: + 20%).
2. When the controller calculates the positions fully close or fully open, the
actuator runtime is extended + 150% to ensure the right actuator position
synchronized to the control algorithm. (RDF3..., 4...: SW < 3.1: + 20%).
3. After the actuator reaches the position calculated by the controller, a waiting
time of 30 seconds is applied to stabilize the outputs.
Electrical heater
control signal
(2-position)
The electrical heater receives an ON command via the auxiliary heating control
output Y21:
1. When the acquired room temperature is below “setpoint for electric heater”.
2. When the electrical heater has been switched off for more than 1 minute.
The OFF command for the electrical heater is output:
1. When the acquired room temperature is above the setpoint (electric heater).
2. When the electrical heater has been switched on for more than 1 minute.
Caution!
DC 0..10 V control

Fan control
The fan operates in automatic mode or at the selected speed with 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
closes and the fan switches off or stays at fan speed 1 (parameter P60)
Factory setting for P60,:
 RDF600...
fan Off in dead zone
 RDF3..., RDF4... fan speed1 in dead zone
The individual switching points for ON of each fan stage can be adjusted via control
parameters P55 – P57. The fan speed switch-off point is 20% below the switch-on
point. The diagram below shows fan speed control for continuous PI control.

Fan operation as per
heating/cooling
mode, or disabled
Fan operation can be limited to be active only in cooling or heating mode, or even
totally disabled via control parameter “Fan operation” P52. When fan operation is
disabled, the fan symbol on the display disappears and actuating the fan button
has no influence. This function allows for using the controller in universal
applications such as floor heating with fan coil cooling etc.
Fan minimum ontime
In automatic mode, a dwelling time of 2 minutes (factory setting) is active. The fan
maintains each speed for at least 2 minutes before it changes to the next speed.
This minimum on-time can be adjusted from 1…5 minutes via parameter P59.
Fan operation in
dead zone
In automatic fan mode and with the room temperature in the dead zone, the control
valve normally is closed and the fan is disabled. With the fan kick function, the fan
can be released from time to time at low speed for minimum on-time (see above)
even if the valve is closed.
This function can be used to avoid damage from moisture due to a lack of air circulation, or to allow a return air sensor to measure the correct room temperature.

change to 12-hour format, press + passing 23:59 or press - passing 00:00 and
vice-versa to return to 24-hour format.
2. Confirm the time of day by pressing and the weekday indicator starts to flash.
3. Press + or - to set the current weekday.
4. Confirm the current weekday by pressing .
Power failure
In the event of a power failure, the clock stops, but its last time is stored. This time
information is reloaded and starts running after power up. On RDF400.01, the clock
flashes to indicate that there was a power failure until the time is confirmed by
pressing , or readjusted by following the above procedure.

Error handling
Temperature out of
range
When the room temperature is outside the measuring range, i.e. above 49 °C or
below 0 °C, the limiting temperatures flash, e.g. “0 °C” or “49 °C”.
Output Y11 is energized if the current setpoint is not set to “OFF”, the controller is
in heating mode and the temperature is below 0 °C. For all other cases, output Y11
is de-energized. The controller resumes Comfort mode after the temperature
returns to within the measuring range.
Power failure
In the event of a power failure, all working conditions (operating mode, setpoint, fan
stage, all control parameter settings) are stored without time limitation.
When power returns, the thermostat reloads this data and continues to work in the
same conditions as before.
For thermostats with auto timer refer to section 4.10.
4.12
Infrared remote control
Use the IRA211 infrared remote control to operate a controller with built-in infrared
receiver. The following operations can be carried out remotely:
 Select operating modes Protection, Comfort or Auto Timer.
 Adjust setpoint in Comfort mode.
 Select fan modes Automatic or Manual.
A buzzer in the thermostat indicates remote control command reception.
Infrared remote control can be disabled via parameter P70.

Control parameters
A number of control parameters can be readjusted to optimize control performance.
These parameters can also be set during operation without opening the unit. In the
event of a power failure, all control parameter settings are retained.
The control parameters are divided in two levels:
 “Service” level, and
 “Expert” level, including Diagnostic and Test
The “Service” level contains a small set of parameters to set up the controller for
the HVAC system and to adjust the user interface. These parameters can usually
be adjusted any time.
Change parameters in the “Expert” level only carefully, as they impact control
performance and functionality of the controller.
Parameter setting
Change the parameters as follows:
Enter only “Service”
level
1. Set the controller to Protection
*)
2. Press buttons + and - simultaneously for 4 seconds.
Release and press button + again within 2 seconds until the display shows

5.1
Mounting and installation
Mount the room controller on the conduit box. Do not mount on a wall in niches or
bookshelves, behind curtains, above or near heat sources, or exposed to direct
solar radiation. Mount about 1.5 m above the floor.
Mounting /
dismounting
 Devices must be mounted on clean, dry indoor place without direct airflow from
a heating / cooling device, and not be exposed to dripping or splashing.
 RDF3... / RDF400… : In case of limited space in the conduit box use the
mounting bracket ARG70.3 to increase the headroom by 10mm.
 Before removing the front cover, disconnect the power supply.
Wiring
See the mounting instructions enclosed with the thermostat:
M3076... for RDF3..., RDF4... ; M3063 for RDF600... .
 Comply with local regulations to wire, fuse and earth the controller
 Properly size the cables to the controller, fan and valve actuators for AC 230 V
mains voltage
 Use only valve actuators rated for AC 230 V on RDF300… / RDF400… /
RDF600...
 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
 Isolate the cables of SELV inputs X1-M/X2-M if the conduit box carries AC 230 V
mains voltage
 Inputs X1-M or X2-M of different units (e.g. summer/winter switch) may be
connected in parallel with an external switch. Consider overall maximum contact
sensing current for switch rating
 No metal conduits
 No cables provided with a metal sheath
 Disconnect from supply before opening the cover
Commissioning
Set the controller application via the DIP switches before snapping the front panel
on the mounting base.
After power is applied, the controller carries out a reset during which all LCD
segments flash indicating that the reset was correct. After the reset, which takes
about 3 seconds, 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 entire system (see “Set control parameters”).
Control sequence
 The control sequence may need to be set via parameter P01 depending on the
application. The factory setting for the 2-pipe application is “Cooling only”; and
“Heating and Cooling” for the 4-pipe application

Setpoint and range
limitation
 When the controller is used with a compressor, the minimum output on-time
(parameter P48) and off-time (parameter P49) for Y11/Y21 must be adjusted to
avoid damaging the compressor and shortening its life
 Recalibrate the temperature sensor if the room temperature displayed on the
controller does not match the room temperature measured. To do this, change
parameter P05
 We recommend to review the setpoints and setpoint ranges (parameters
P08…P12) and change them as needed to achieve maximum comfort and save
energy

Disposal
The device is classified as waste electronic equipment in terms of the European
Directive 2002/96/EC (WEEE) and should not be disposed of as unsorted municipal waste.
The relevant national legal rules are to be adhered to. Regarding disposal, use
the systems setup for collecting electronic waste.
Observe all local and applicable laws.
