Functions
4.1
Temperature control
Setting of the control parameters (P01, etc., mentioned throughout the document) is
described in section 4.15.
The thermostat 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 delivering actuator control commands to heating and/or
cooling equipment. The following control outputs are available depending on the
thermostat type:
1- / 3-speed fan:
• On/Off control on RDG100, RDG100T, RDG100T/H, RDG110
• Modulating PI / P control with 3-position control output on RDG100, RDG100T,
RDG100T/H
• Modulating PI / P control with PWM output on RDG100, RDG100T, RDG100T/H
• Modulating PI / P control with DC 0…10 V control output on RDG160T
ECM fan:
• On/Off control on RDG160T
• Modulating PI / P control with DC 0…10 V control output on RDG160T
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 modulating PI control is adjustable via parameter P35.
Display
/
Concurrent display of
°C and °F
The display shows the acquired room temperature or the Comfort setpoint, 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 thermostat 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's status. Thus, the symbols are displayed even when the thermostat operates in
symbols are
the neutral zone. For all other cases, the heating and cooling
displayed when the heating or cooling output is activated.
Concurrent display of the current temperature or setpoint in °C and °F (parameter
P07) is possible on the thermostats without 7-day time program.

4.2
Operating modes
Select the thermostat's operating mode via the operating mode button on the unit or
operating mode input (e.g. keycard occupancy sensor), when X1, X2, or D1 is set to 3
(P38, P40, P42). 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 thermostat maintains the room temperature setpoint which can
be adjusted via the rotary knob. The fan can be set to automatic or manual fan
speed: Low, medium or high.
Economy mode
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
Protection mode
Auto Timer mode
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).
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).

4.3
Comfort mode
Room temperature setpoints
The factory setting for the Comfort basic setpoint is 21 °C and can be changed via
parameter P08.
The setpoint in Comfort mode can be adjusted via the rotary knob.
Temporary setpoint
If the "Temporary setpoint function" is enabled via parameter P69, the setpoint
adjusted via the rotary knob is set back to the Comfort basic setpoint when the
operating mode changes.
Setpoint limitation
For comfort or energy saving purposes, the setpoint setting range can be limited to
minimum (P09) and maximum (P10).
P09 < P10
(comfort concept)
• If the minimum limit P09 is set lower than the maximum limit P10, both heating and
cooling are adjustable between these 2 limits.
• The customer adjusts the desired setpoint and the thermostat controls the room
temperature accordingly.
• For 4-pipe applications *), the selected comfort setpoint is in the middle of the
dead zone (P33). The unit stops to energize the heating / cooling outputs as soon
as the room temperature reaches the dead zone.
Example
5°C
P09 ≥ P10
(energy saving concept)
18°C
P09
25°C
P10
40°C
Cooling setpoint adjustable 18…25 °C
Heating setpoint adjustable 18…25 °C
• If the minimum limit P09 is set higher than the limit P10, then
– The setting range of cooling setpoint is from P09…40 °C in place of 5…40 °C
– The setting range of heating setpoint is from 5…P10 °C in place of 5…40 °C
This allows the user to limit the maximum heating setpoint and the minimum cooling
setpoint. This concept helps to save energy costs.
• For 4-pipe applications:
– The thermostat runs with the setpoint of the active sequence:
In heating mode, the heating setpoint is active and adjustable via rotary knob.
In cooling mode, the cooling setpoint is active and adjustable via rotary knob.
– Switching from the heating setpoint to the cooling setpoint and vice-versa
occurs when the room temperature reaches the adjusted limitation (P09 or
P10) of the inactive sequence. E.g. the thermostat is in heating sequence and
runs with the heating setpoint. When the room temperature reaches P09, the
thermostat switches to cooling mode and runs with the cooling setpoint, as
long as the room temperature does not drop below P10.

Economy mode
Use control parameters P11 and P12 to adjust the Economy mode setpoints.
The heating setpoint is factory-set to 15 °C, and the cooling setpoint to 30 °C.
Protection mode
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.
Caution
If a setpoint is set to OFF (P65, P66), the thermostat 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 overtemperature in cooling mode!
The Economy setpoints are accessible at the service level (P11, P12); the Protection
setpoints at the expert level (P65, P66).

Setpoints and sequences
4.4.1
2-pipe and 2-stage applications
On changeover applications, the Comfort setpoints for heating and cooling sequence
are the same (w).
On 2-pipe applications with electric heater, the Comfort setpoint is either at the first
heating sequence (in heating mode) or at the cooling sequence (in cooling mode).
On 2-pipe applications with radiator, the Comfort setpoint is either at the radiator
sequence (in heating mode) or at the cooling sequence (in cooling mode).
The setpoints for Economy and Protection mode are below the Comfort setpoints
(heating) and above the Comfort setpoints (cooling).
They can be set via parameters P11, P12 (Economy mode) and P65, P66 (Protection
mode).

Additional features
3191D124
The water temperature acquired by the changeover sensor (QAH11.1 + ARG86.3) is
used to change over from heating to cooling mode, or vice versa.
• When the water temperature is above 28 °C (adjustable via parameter P37), the
thermostat changes over to heating mode.
It stays in heating mode until the temperature falls below 16°C (adjustable
viaparameter P36)
• When the water temperature is below 16 °C (P36), the thermostat changes over to
cooling mode.
It stays in cooling mode until the temperature rises above 28°C (P37).
• If the water temperature is between the 2 changeover points immediately after
power-up (inside the hysteresis), the thermostat starts in previous mode.
The water temperature is acquired at 30-second intervals and the operating state is
updated accordingly.

The commissioning of the parameter Operating action (P39, P41, P42) has in this
case no effect.
The assignment is fix: Contact open

Contact closed  cooling mode
Manual heating /
cooling changeover
• Manual heating / cooling changeover means selection via changeover button on the
thermostat by repeatedly pushing the button until the required mode is shown on
the display (automatic changeover is done via an external sensor / switch
connected to X1, X2, or D1)
• If manual heating / cooling changeover is commissioned (P01 = 2), then heating /
cooling mode cannot be changed via changeover sensor / switch; it will remain in
the last mode as selected locally via button.
External / return air
temperature sensor
The thermostat 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.

Purge function
Caution
The changeover sensor ensures 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. This function is available on all RDG variants for applications 2-pipe
changeover and on RDG160T also for the 4-pipe changeover.
The purge function (parameter P50) must be disabled if the thermostat is 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, in order to avoid damage from moisture due to lack of air circulation.
See also section 4.9 "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 On/Off control output 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; output Y11/Y21 may not hold the minimum 1-minute
On/Off time.
If parameter P48 or P49 is set to above 1 minute, the minimum On/Off time for the
control output is maintained as set, even if the setpoint or changeover mode is
readjusted.
This function is only available for On/Off control with RDG100, RDG100T,
RDG100T/H, RDG160T and RDG110.
Floor heating /
Floor cooling
All heating sequences can also be used for floor heating.
You can use fan coil heating / cooling sequences for floor heating or cooling by
disabling the fan via parameter P52.

Floor temperature
limitation function
The temperature should be limited for 2 reasons: comfort and protection of the floor.
The floor temperature sensor, connected to multifunctional input X1 or X2, acquires
the floor temperature. If the temperature exceeds the parameterized limit (parameter
P51), the heating valve is fully closed until the floor temperature drops to a level 2 K
below the parameterized limit.
This function is factory-set to OFF (disabled).
Input X1 or X2 must be commissioned accordingly (P38 or P40 = 1).
See section 4.10 "Multifunctional input".
Living rooms:

Supply air temperature
limitation (RDG160T)
Either floor temperature sensor or external room temperature sensor can be used.
This function increases the comfort in the room by keeping the supply air temperature
of the fan coil unit between the selected minimum and maximum temperature limits.
If the supply air temperature exceeds a limit, the thermostat reduces the
corresponding valve position until the supply air temperature is back in the limits.
In case the air flow is too low (especially with DC 0...10 V fans), this prevents cold air
from dumping into the room / warm air from bubbling straight up instead of circulating.
To enable this function, the multifunctional input, to which the supply air sensor is
connected, needs to be set to "Supply air sensor" (e.g. P38=9). Then the parameters
for the limits are visible (P63: minimum supply air temperature, P64: maximum supply
air temperature).

Note
For applications with electric heater and radiator, this function is available only on the
cooling valve (in cooling mode).
Dewpoint monitoring
Dewpoint monitoring is essential to prevent condensation on the chilled ceiling
(cooling with fan disabled, parameter P52). It helps avoid associated damage to the
building.
A dewpoint sensor with a potential-free contact is connected to multifunctional input
X1, X2 or D1. 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.
The input must be commissioned accordingly (P38, P40, P42).
See section 4.10 "Multifunctional input".
Button lock
If the button lock function is enabled by parameter P14, the buttons will be locked or
unlocked by pressing the right button for 3 seconds.
If "Auto lock" is configured, the thermostat will automatically lock the buttons 10
seconds after the last adjustment.
Operating mode

Qx- relay switching functions (RDG160T only)
The following special functions are available on the RDG160T and allow the control of
external equipment connected to the Q1, Q2 and Q3 relay outputs.
• Switch OFF external equipment when the thermostat is in Protection Mode
• Switch ON external equipment during heating / cooling demand
• Output heating / cooling sequence
The relay output corresponding parameters need to be set to enable the function.
• Function on Q1, set parameter P72. Test relay function via diagnostic d08.
• Function on Q2, set parameter P73. Test relay function via diagnostic d09.
• Function on Q3, set parameter P74. Test relay function via diagnostic d10.
Notes
Switch OFF external
equipment in
Protection mode
• Those functions are available when DIP4 is set to OFF (EC fan).
• It is not suggested to use those functions in combination with the On/Off valve
control (P46/P47=1) to guarantee the temperature accuracy. If this combination is
requested, the total maximum current on the relay outputs (Q1+Q2+Q3) should not
exceed 2A.
The external equipment (e.g. fan coil unit) can be switched OFF via relay output, in
order to reduce energy consumption when the thermostat is in Protection mode and
no temperature control is requested.
The function can be enabled by setting the corresponding Qx- parameter to 1.
Relay contact is open when the thermostat is in protection mode.
Switch ON contact
during Heat / Cool
demand
Note
During the heating or cooling demand, the relay contact can be energized to control
an external equipment, for example to run the pump of a water system (fan coil).
To reduce the wear and tear of the HVAC equipment, the minimum output on-time and
off-time of the Qx- relay output can be adjusted from 1 to 20 minutes via parameters
P48 and P49. The factory setting is 1 minute.
The relay output remains OFF if the heating is provided ONLY by electric heater
(application 2-pipe electrical heater, heating by electrical heater, cooling by fan coil) or
radiator.
2-pipe water system (with one pump):
• Enable the function by selecting the corresponding output parameter to 2
• Connect the external equipment to selected relay output
• In case of heating / cooling demand, the output contact is energized
4-pipe water system (with two pumps):

4.7.4
2-pipe fan coil unit with electric heater
Heating or cooling with
auxiliary heater
On 2-pipe applications with electric heater, the thermostat controls a valve in heating /
cooling mode with changeover, heating only, or cooling only plus an electric heater.
Cooling only is factory set (P01=1) with enabled electric heater (P13).
Electric heating, active in
cooling mode
In cooling mode, the valve receives an OPEN command if the acquired temperature is
above the setpoint.
The electric heater receives an ON command if the acquired room temperature drops
below "setpoint" minus "dead zone" (= setpoint for electric heater) while the electric
heater is enabled (parameter P13 = on).
Note: "Setpoint for electric heater" is limited by parameter "Maximum setpoint for
Comfort mode" (P10).
Electric heating in
heating mode
In heating mode, the valve receives an OPEN command if the acquired temperature is
below the setpoint. The electric heater is used as an additional heating source when
the heating energy controlled by the valve is insufficient.
The electric heater receives an ON command, if the temperature is below "setpoint"
minus "setpoint differential" (= setpoint for electric heater).
Electric heating and
manual changeover
The electric 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
electric heater"
Remote enabling / disabling of the electric heater is possible via input X1, X2 or D1 for
tariff regulations, energy savings, etc.
Input X1, X2, or D1 must be commissioned accordingly (parameters P38, P40, P42).
See section 4.10 "Multifunctional input".
Caution
On/Off electric heater
on RDG160T with
ECM fan
An electric heater must always be protected by a safety thermostat!
• With a DC 0...10 V (ECM) fan it is possible to select On/Off control for the electric
heater by setting parameter P47 = 1. The electric heater has to be connected to
output Q2.
• The electric heater starts with a delay of 15 s, to make sure the fan delivers
sufficient air flow to dissipate the heat.
• To avoid overheating of the electrical heater, the thermostat guarantee at least a
fan speed II (middle value between Vmin (P56) – Vmax (P55)) when the electrical
heater need to be energized.
• Adaptive temperature compensation P45 need to be set accordingly
(Refer to section 4.8).

On 2-pipe applications with radiator, the thermostat controls a valve in heating /
cooling mode with changeover, heating only, or cooling only plus a radiator valve.
Cooling only is factory-set (P01=1).
Radiator, active in
cooling mode
In cooling mode, the valve receives an OPEN command if the acquired temperature is
above the setpoint.
The radiator receives an ON command if the acquired room temperature drops below
"setpoint" minus "dead zone" (= "setpoint for radiator").
Radiator in heating mode
In heating mode, the radiator receives an OPEN command if the acquired temperature
is below the setpoint. The fan coil unit is used as an additional heat source when the
heat energy controlled by the radiator is insufficient.
The fan coil unit receives an ON command if the temperature is below "setpoint"
minus "setpoint differential" (= setpoint for fan coil unit).

4-pipe fan coil unit
Heating and cooling
On 4-pipe applications, the thermostat controls 2 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 changeover
The heating or cooling output can be released via operating mode button if parameter
P01 is set to manual (P01=2).
"Main and secondary"
application (4-pipe with
changeover)
If parameter P01 is set to changeover (P01=3), the heating and cooling output is
swapped according to the changeover sensor input status (see automatic heating and
cooling changeover sensor, section 4.6). This mode is used for the so-called "Main
and secondary" application. This is a 4-pipe fan coil unit system with different capacity
of the 2 coils. The water circuit is changed to optimize the energy exchange
depending on the season (summer/winter):
– Winter: Large coil (V1) for heating, small coil (V2) for cooling
– Summer: Large coil (V1) for cooling, small coil (V2) for heating

(Y…, see Mounting Instructions) when
1. the acquired room temperature is below "Setpoint for electric heater"
2. the electric heater has been switched off for at least 1 minute
The OFF command for the electric heater is output when
1. the acquired room temperature is above the setpoint (electric heater)
2. the electric heater has been switched on for at least 1 minute
Caution
Note!
A safety thermostat (to prevent overtemperatures) must be provided externally.

Adaptive temperature
compensation for electric
heater (RDG160T,
RDG110)
When an electric heater is connected directly to the On/Off output (RDG160T: Q2,
RDG110:Y21), the current causes the relay contact to heat up. This falsifies the
reading of the internal temperature sensor. The thermostat compensates the
temperature if the rated current/power of the electric heating is entered in the
parameters.
RDG160T:
P45 (power el. heater). Factory setting: 0.0 kW, setting range: 0.0 …1.2 kW.
RDG110:
P46 (load current el.heater): Factory setting: 1A, setting range: 1…5A.
This function is available with RDG100, RDG100T and RDG100T/H only.
3-position
control signal
Heating: Output Y1 provides the OPEN command, and Y2 the CLOSE command to
the 3-position actuator. Relay function Y1/Y2 and wiring can be tested via diagnostic
parameter d05. Cooling: Idem with Y3 and Y4. Relay function Y3/Y4 and wiring can be
tested via diagnostic parameter d06.
The factory setting for the actuator's running time is 150 seconds. It can be adjusted
via parameters P44 (Y1 and Y2) or P45 (Y3 and Y4).
The parameters are only visible if 3-position is selected via DIP switches 4 and 5.
1. When the thermostat is powered up, a closing command for the actuator running
time + 150% is provided to ensure that the actuator fully closes and synchronizes
to the control algorithm.
Synchronization
2. When the thermostat calculates the positions "fully close" or "fully open", the
actuator's running time is extended + 150% to ensure the right actuator position is
synchronized to the control algorithm.
3. After the actuator reaches the position calculated by the thermostat, a waiting time
of 30 seconds is applied to stabilize the outputs.
This function is available with RDG100, RDG100T and RDG100T/H only.
PWM control
The demand calculated by PI control from the current room temperature and setpoint
is provided via Y1 and Y3 to the valve actuator as a PWM signal (pulse width
modulation) for thermal actuators. The output is activated for a period proportional to
the heating / cooling demand and then switched off for the rest of the PWM interval.
The interval is 150 seconds (factory setting). It can be adjusted via parameters
P44 (Y1) or P45 (Y3). These parameters are only visible if 2-position is selected via
DIP switches 4 and 5 and if PWM is selected via P46 and P47.
Note!
For PWM, the integral time (P35) must be set to 0.
For thermal valve actuators, set the running time to 240 seconds.
PWM for thermal
valve actuators
Note!
PWM for electric heaters
Note!
• Never apply PWM to an electromotoric actuator
• It is not possible to ensure exact parallel running of 2 or more thermal valve
actuator. If several fan coil units are driven by the same thermostat, preference
should be given to electromotoric actuators with On/Off or 3-position position
control.
For electric heaters, set the running time to 90 seconds.
To avoid burn-off of mechanical contacts by frequent switching, use a current valve in
place of a relay or contactor.
For PWM, the integral time (P35) must be set to 0.

The following options are available:
• Fan does not run in the dead zone (P15=0)
• Fan runs at low speed in Heating and Cooling mode (P15=1)
• Fan runs at low speed in Cooling mode only (P15=2)
The functions "Fan in dead zone" (P15) and "Fan kick" (P60) are combined as follows:
• P60 = 0
Fan runs continuously in the dead zone, P15 has no influence
• P60 = OFF Fan operation in dead zone according to P15
When the fan starts from standstill, it starts at speed 3 for 1 second to ensure safe fan

Fan failure
In case of fan failure, the thermostat cannot protect the electric heater against
overtemperature. For this reason, the electric heater must feature a separate safety
device (thermal cutout).
Clean fan filter

The "Clean fan filter reminder" function counts the fan operating hours and displays
message "FIL
" to remind the user to change / clean the fan filter as soon as the
threshold is reached. This does not impact the thermostat's operation, which continues
to run normally. The function is set via parameter P62 (default = Off (0)).
The "Clean filter reminder" is reset when the operating mode is manually set to
Protection and back.

Multifunctional input, digital input
The thermostat has 2 multifunctional inputs X1 and X2 and a digital input D1.
A sensor type NTC like the QAH11.1 (AI, analog input) or a switch (DI, digital input)
can be connected to the input terminals. The functionality of the inputs can be
configured via parameters P38 for X1, P40 for X2, and P42 for D1.

Sensor input for external room temperature sensor or
return air temperature sensor to acquire the current
room temperature, or floor heating temperature
sensor to limit the heating output.
Note: The room temperature is acquired by the builtin sensor if the floor temperature limitation function is
enabled via parameter P51.
Sensor input for automatic heating / cooling
changeover function.
A switch can also be connected rather than a sensor
Important: Switch closed means always cooling, (this
cannot be changed), see section 4.6.
Digital input to switch over the operating mode to
Economy.
If the operating mode switchover contact is active,
user operations are ineffective and "OFF" is
displayed.
Digital input for a dewpoint sensor to detect
condensation. Cooling is stopped if condensation
occurs.
Digital input to enable / disable the electric heater via
remote control.
Digital input to signal an external fault
(example: dirty air filter).
If the input is active, "ALx" is displayed
(Alarm x, with x = 1 for X1, x = 2 for X2, x = 3 for D1).
Note: Fault displays do not influence the thermostat's
operation. They merely represent a visual signal.
Sensor input to acquire the supply air temperature.
The thermostat controls the room temperature via the
built-in sensor. The control output (DC 0...10 V) is
reduced if the supply air temperature exceeds the
min / max limits (P63, P64).

Operational action can be changed between normally open (NO) and normally closed
(NC) via parameter P39, P41 (or P43 if it is a digital input).
Each input X1, X2 or D1 must be configured with a different function (1…5, 9).
Exception: 1, 2 or 3 inputs can be configured as alarm inputs (6).
X1 is factory-set to "External sensor" (1), X2 to "Heating / cooling changeover" (2),
and D1 to operating mode changeover (3).
If a multifunctional input is configured as analog: "Err" will be displayed when the
output is out of range (0...49 °C), open or shorted.

Temperature out
of range
Handling faults
When the room temperature is outside the measuring range, i.e. above 49 °C or below
0 °C, the limiting temperatures blink, e.g. "0 °C" or "49 °C".
In addition, the heating output is activated if the current setpoint is not set to "OFF",
the thermostat is in heating mode and the temperature is below 0 °C.
For all other cases, no output is activated.
The thermostat resumes Comfort mode after the temperature returns to within the
measuring range.
Fault "Er1" on display
When the built-in sensor fails and no external sensor is connected, the thermostat
shows the fault message "Er1" on the display. The thermostat needs to be replaces if
the room temperature needs to be measured with the built-in sensor.

Mounting and installation
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
• The room thermostat must be mounted in a clean, dry indoor place and must not be
exposed to drip or splash water.
Wiring
See Mounting Instructions (M3181) enclosed with the thermostat.
• Comply with local regulations to wire, protection and earth the thermostat.
• The device has no internal fuse for supply lines to fan and actuators. To avoid risk
of fire and injury due to short-circuits, the AC 230 V mains supply line must have a
circuit breaker with a rated current of no more than 10 A.
• Properly size the cables to the thermostat, fan and valve actuators for AC 230 V
mains voltage.
• Use only valve actuators rated for AC 230 V on RDG100…, RDG110 and on
RDG160T if AC 230V is connected to the "L" terminal.
• The wiring cross section used for power supply (L, N), fan (Q1, Q2, Q3, N) and 230
V outputs (Yx - N) must be adapted to the preceding overload protection elements
(10A) under all circumstances. Comply under all circumstances with local
regulations.
• Isolate the cables of inputs X1-M / X2-M and D1-GND if the conduit box carries
AC 230 V mains voltage.
• On the RDG100.. and RDG110, inputs X1-M and X2-M carry mains potential.
If the sensor’s cables are extended, they must be suited for mains voltage.
• Inputs X1-M, X2-M or D1-GND 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.
• Selectable relay function (RDG160T). Consider overall maximum current thought
the relays.
• Disconnect power supply before removing the thermostat from the mounting plate!
Commissioning
Select the application and the type of control output via the DIP switches before fitting
the thermostat to the mounting plate.
After power is applied, the thermostat carries out a reset during which all LCD
segments blink, indicating that the reset was correct. After the reset, which takes about
3 seconds, the thermostat is ready for commissioning by qualified HVAC staff.
The control parameters of the thermostat can be set to ensure optimum performance
of the entire system (see section 4.15, 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.
• When the thermostat is used in connection with a compressor, the minimum output
on-time (parameter P48) and off-time (parameter P49) for Y11/Y21 must be
adjusted to avoid damage to the compressor and shortening its life.

Calibrate sensor
• Recalibrate the temperature sensor if the room temperature displayed on the
thermostat does not match the room temperature measured. To do this, change
parameter P05.
Adaptive temperature
compensation for el.
heater
• When an electric heater is connected directly to output Y21, the rated current of the
electric heating should be entered in parameter 46 (RDG110 only, device index D
and higher), see section 4.8.
Default setting: 1 A for loads ≤ 1 A.
Setpoint and setpoint
setting range limitation
• We recommend to review the setpoints and setpoint setting ranges (parameters
P08…P12) and change them as needed to achieve maximum comfort and save
energy.
