2.4 Integration via KNX bus
The RDF room thermostats can be integrated as follows:
∂ Integration into Synco 700 system via LTE Mode (easy engineering).
∂ Integration into Synco living via group addressing (ETS).
∂ Integration into Desigo and Apogee via group addressing (ETS) or
individual addressing.
∂ Integration into third-party systems via group addressing (ETS).
The following KNX functions are available:
∂ Central time program and setpoints, e.g. when using the RMB795 central
control unit.
∂ Outside temperature or time of day via bus displayed on thermostat.
∂ Remote operation and monitoring, e.g. using the RMZ792 bus operator unit.
∂ Remote operation and monitoring with web browser using the OZW772 web
server.
∂ Maximum energy efficiency due to exchange of relevant energy information,
e.g. with Synco 700 controllers (e.g. heating demand, cooling demand).
∂ RDF301.50 and RDF600KN/S only: 4 buttons to control KNX actuators via KNX
S-Mode
("switching groups" with functions such as switching, dimming, blinds control,
8-bit scene).
∂ RDF301.50H only: 4 buttons for Hotel applications to control via KNX S-Mode.
Same functions as RDF301.50, but with dedicated button labels for hotel
applications: Make Up Room, Do Not Disturb.
∂ Alarming, e.g. external fault contact, condensation, clean filter, etc.
∂ Monitoring input for temperature sensor or switch.
Engineering and commissioning can be done using…
– local DIP switches / HMI
– Synco ACS service tool
– ETS
The RDF room thermostats are especially tailored for integration into the Synco
700 system and operate together in LTE Mode. This extends the field of use of
Synco for individual room control in conjunction with fan coil units, VAV, chilled
ceilings and radiators.
Thanks to S-Mode extension to the QAX9x3 central apartment unit, communicating
room thermostats can be easily integrated into Synco living systems. Using the SMode data points of the central apartment unit, additional room information can be
exchanged with the room thermostat via KNX TP1 (RF function is not available on
the room thermostats). To make the integration, the ETS engineering tool is
required.

Comfort mode can be temporarily extended (e.g. working after business hour or on
weekends) when the thermostat is in Economy mode. The operating mode button
switches the operating mode back to Comfort for the period preset in P68.
Press the operating mode button again to stop the timer.
The following conditions must be fulfilled:
∂ mode selection via operating mode button is set to "Protection-Auto"
(P02 = 1) and the time schedule via bus is Economy.
∂ Parameter P68 (extend Comfort period) is greater than 0.
During the temporary Comfort mode extension, symbol appears.
If parameter P68 (extend Comfort period) = 0, extended Comfort cannot be
activated; pressing the operating mode button will switch the thermostat to
Protection.
If the operating mode switchover contact is active, pressing the operating mode
button will show "OFF" (blinking).
3.2.2 Communication examples
The following examples show two typical applications of a central time schedule in
conjunction with local control of the room operating mode.
The room operating mode in rooms 1…2 of a building is determined by the time
schedule. Window contacts are fitted in all rooms.
The following conditions are specified:
The rooms are used and controlled by the time schedule as follows:
– Night setback from 17:00 to 08:00 (Economy)
– Protection from 20:00 to 06:00
– Lunch break from 12:00 to 13:00 (Pre-Comfort).
The substitution (parameter P88) for Pre-Comfort via bus is set on the thermostats
as follows:
– Room 1: Comfort (1)
– Room 2: Economy (0).

Application with hotel presence detection function via key card reader
In room 4, hotel presence detection is selected via parameter P77, and the
multifunctional input X1/X2(set parameter P38 or P40 to 10) is connected to a card
reader in a hotel application.
∂ At 6:00 when the room is vacant, i.e. no key card inserted in the card reader,
the thermostat’s operating mode is set to Economy. (1)
∂ At 8:00 when the room is occupied, i.e. a key card inserted in the card reader,
the operating mode returns from Economy to the previous mode1)(2)
∂ A guest changes the operating mode to Comfort by pressing the operating
mode button. (3)
∂ The guest then opens a window and the operating mode immediately switches
to Protection. As soon as the window is closed, the operating mode is returns
to Comfort. (4)
∂ If the guest leaves the hotel room or removes the key card, the operating
mode returns to Economy, and the thermostat remains on Economy as the
local HMI2) is locked, i.e. the operating mode cannot be changed if no key card
is inserted. (5)
∂ When the guest returns to the hotel (room occupied), the operating mode
returns to the mode (Comfort) set previously by the guest. (6)
∂ When the guest turns off the room thermostat before going to sleep, the room
operating mode switches to Protection. (7)
∂ As the guest wakes up, he/she turns on the thermostat and the operating
mode switches to Comfort. (8)
∂ As soon as the room is unoccupied (guest leaves the room), the thermostat
returns to Economy to save energy. (9)
∂ When the guest checks out of the hotel, the operating mode can be set to
Protection via bus. (10)
Note:
1) The previous mode is the operating mode selected by either hotel guests via local

3.3 Room temperature setpoints
3.3.1 Description
The factory setting for the Comfort basic setpoint is 21 °C and can be changed in
the thermostat’s EEPROM via parameter P08 or via bus with communication object
"Comfort basic setpoint". The last intervention always wins.
The Comfort setpoint can be adjusted via the +/- buttons,
or via bus from a remote device like a touchpanel, operating unit, etc.
The last intervention always wins.
If the "Temporary setpoint" function is enabled via parameter P69, the Comfort
setpoint adjusted via the +/- buttons or via bus is set back to the Comfort basic
setpoint stored in P08 when the operating mode changes.
For comfort or energy saving purposes, the setpoint setting range can be limited to
minimum (P09) and maximum (P10).
∂ 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
40°C
25°C18°C
P10
P09
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.
Example
5°C
40°C
25°C21°C
P09
P10
Cooling setpoint adjustable 25…40 °C
Heating setpoint adjustable 5…21 °C
For heating and cooling applications (e.g. 4-pipe):
– P09 is the setpoint for cooling and P10 the setpoint for heating.
– The setpoint cannot be adjusted via the rotary knob.
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.

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 (Economy or Protection) is set to OFF, the thermostat does not control
the room temperature in the corresponding mode (heating or cooling).
This means no protective heating or cooling function and thus risk of frost in
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).

∂ The supported communication objects are different in LTE Mode and S-Mode.
∂ Changes via the local HMI or via tool have the same priority (last always wins).
∂ Setting the Comfort basic setpoint will reset the runtime Comfort setpoint to the
basic setpoint.
∂ Central setpoint shift is used for summer / winter compensation in particular.
∂ Setpoint shift does not affect the setpoints stored in parameters P08, P11, P12,
P33.
∂ Local shift and central shift are added together.
∂ Applies only to Comfort and Economy setpoints; Protection setpoints are not
shifted centrally.
∂ The resulting (current) setpoint heating and cooling is limited by the Protection
setpoint; if Protection setpoint is OFF, then minimum 5 °C and maximum 40 °C
are used.
∂ The resulting setpoints for cooling and heating of the same operating mode have
a minimum distance of 0.5 K between them.
∂ The result of local and central shift, together with the room operating mode, is
used by the thermostat for temperature control (current setpoint).
∂ The room thermostat always adopts the received setpoints from the controller
RMB795. Thus the Comfort setpoints locally adjusted on the RDF600KN room
thermostats are overwritten by the Comfort setpoints of the room group
(i.e. within every 15 min).
∂ On RMB SW Version >= 2.0 it is possible to define under which circumstances
the controller has to send out the setpoints:
- Always (every 15min)
- Not in Comfort mode
- Only when changed
∂ See "Setpoint priority" and "Setpoint Master" functions on RMB795B.
∂ RDF600KN SW version < V1.8: The local Comfort setpoints are overwritten only
if the RMB setpoints are changed.
3.4 Applications overview
The thermostats support the following applications, which can be configured using
the DIP switches inside the front panel of the unit or a commissioning tool.
All DIP switches need to be set to OFF (remote configuration, factory setting) to
select an application via commissioning tool.

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.
The "Purge" function (parameter P50) must be disabled if the thermostat is used in
compressor-based applications.
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 3.8 for "Fan kick function".
Limit the ON/OFF switching cycle to protect the HVAC equipment, e.g. compressor
and reduce wear and tear. The minimum output ON-time and OFF-time for 2position 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 state; the outputs 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.
All heating sequences can also be used for floor heating.
You can use fan coil unit heating / cooling sequences for floor heating or cooling by
disabling the fan via parameter P52.
The floor 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.
In case of an external sensor error, if the room temperature drops below the
protection setpoint (e.g. 8 °C), the heating output of the thermostat remains
disabled, until the external sensor fault is removed.
This function is factory-set to OFF via P51 (disabled).
Input X1 or X2 must be commissioned accordingly (P38 or P40 = 1).
See section 3.9 .

3.6.5 4-pipe fan coil unit
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.
The heating or cooling output can be released via operating mode button if
parameter P01 is set to Manual (P01 = 2).
If parameter P01 is set to changeover (P01 = 3), the heating and cooling output is
swapped according to the input state of the changeover sensor / switch / bus input
(see automatic heating and cooling changeover sensor in section 3.5). This mode
is used for the so-called "Main and secondary" application. This is a 4-pipe fan coil
unit system with different capacities 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.

3.6.8 Setpoints and sequences
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).
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).

On 4-pipe applications, the Comfort setpoint (w) is in the middle of the dead zone,
between the heating and cooling sequence.
The dead zone can be adjusted via parameter P33.
If manual changeover is selected, then either the cooling sequence or the heating
sequence is released. In this case, the Comfort setpoint is at the selected heating
or cooling sequence.

*) Only on 2-pipe application
In the ACS tool, Y11 and Y21 are called Y1 and Y2.
The valve or compressor receives the OPEN/ON command via control output Y11
or Y21 when…
1. the acquired room temperature is below the setpoint (heating mode) or above
the setpoint (cooling mode).
2. the control outputs have been inactive for more than the "Minimum output
OFF-time" (factory setting 1 minute, adjustable via parameter P48).
OFF command when…
1. the acquired room temperature is above the setpoint (heating mode) or below
the setpoint (cooling mode).
2. the valve has been active for more than the "Minimum output on-time" (factory
setting 1 minute, adjustable via parameter P49).
The electric heater receives an ON command via the auxiliary heating control
output (Y…, see Mounting Instructions) when…
1. the acquired room temperature is below the "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.
A safety limit thermostat (to prevent overtemperatures) must be provided externally.
When an electric heater is connected directly to the ON/OFF 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.
P45 (load current el. Heater): Factory setting 0kW, setting range: 0.0…1.2 kW.
Output Y11 provides the OPEN command, and Y21 the CLOSE command to the
3-position actuator.
The factory setting for the actuator's running time is 150 seconds. It can be
adjusted via parameter P44.
The parameter is only visible if 3-position is selected via DIP switches.

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.
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.
3.7.2 Control outputs configuration (setting via DIP
switches or tool)
The type of the control outputs on 2-pipe applications (2- or 3-position) is set via
DIP switches (see section 3.4).
The DIP switches have no impact if the application is commissioned via tool.
Control outputs need to be set via ACS in this case.
In the tool, the parameter is called "Output Y1 / Y2", not Y11 / Y2.

The thermostat can control a 1- or 3-speed fan (selected via control parameter
P53). A 1-speed fan is connected to terminal Q1, a 3-speed fan to terminals Q1,
Q2 and Q3.
Fan operation can be limited to be active with cooling only or heating only, or even
be totally disabled via control parameter "Fan operation" P52.
When fan operation is disabled, the fan symbol on the display disappears and
pressing the fan button has no impact.
This function allows you to use the thermostat on universal applications such as
chilled / heated ceilings and radiator, etc. (see section 3.6.6).
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…6 minutes via parameter P59.
In automatic fan mode and with the room temperature in the dead zone, the control
valve is normally closed and the fan 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 temperature sensor to acquire the correct room
temperature.

The periodic fan kick time can be selected individually for Comfort mode via
parameter P60, and for Economy mode via parameter P61.
Note: Fan kick value "0" means the fan runs continuously in the dead zone.
Fan kick value "OFF" means the fan does not run in the dead zone.
Via parameter P15 in "Service Level", the fan speed in the dead zone (in Comfort
mode) can be set according to customer preference.
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).

3.11 KNX communications
The RDF KNX thermostats support communications as per the KNX specification.
S-Mode Standard mode; engineering via group addresses.
LTE Mode Logical Tag Extended mode, for easy engineering,
is used in conjunction with Synco.
3.11.1 S-Mode
This mode corresponds to KNX communications.
Connections are established via ETS by assigning communication objects to group
addresses.
3.11.2 LTE Mode
LTE Mode was specifically designed to simplify engineering. Unlike with S-Mode,
there is no need to create the individual connections (group addresses) in the tool.
The devices autonomously establish connections.
To make this possible, the following circumstances are predefined:
∂ Every device or subdevice is located within a zone
∂ Every data point (input or output) is assigned to a zone
∂ Every data point (input or output) has a precisely defined "name".
Whenever an output and an input with the same "name" are located in the same
zone, a connection is established automatically, as shown in the following diagram.

∂ For a detailed description of KNX (topology, bus supply, function and setting of
LTE zones, filter tables, etc.), see "Communication via the KNX bus for Synco
700, 900 and RXB/RXL, Basic Documentation" [6].
∂ LTE Mode data points and settings are described in the Synco Application
Manual [12].
∂ To engineer and commission a specific system, use the Synco700 planning and
commissioning protocol (XLS table in HIT, [7]).
3.11.3 Zone addressing in LTE Mode (in conjunction with
Synco)
In cases where RDF KNX room thermostats are used in LTE Mode (e.g. in
conjunction with Synco), zone addresses need to be allocated.
The following zone address must be defined together with the Synco devices at the
planning stage depending on the application.
Short description Factory setting Parameter
Geographical zone (apartment) --- (out of service) P82
Geographical zone (room) 1 P83
Heat distr zone heating coil 1 P84
Refr distr zone cooling coil 1 P85
"Subzone" of "Geographical zone" is fix 1 (not adjustable).
The device will send and receive LTE communication signals only if the zone
address is valid (not OSV = out of service).

The zones to be defined are as follows:
Geographical zone
(space zone)
(Apartment . Room . Subzone)
Apartment = ---, 1...126
Room = ---, 1...63
Subzone = fix 1
Zone in which an RDF KNX thermostat is physically located. Other
room-specific devices may also be located in this zone.
Information exchanged in this zone is related specifically to the device
like operating mode, setpoints, room temperature, etc.
The designations "Apartment", "Room" and "Subzone" do not need to
be taken literally. For example, Apartment can be used to refer to a
group of rooms, floor or section of a building. "Room", however, really
does refer to a room.
Subzone is not used for HVAC devices. It is more relevant to other
disciplines, such as lighting. Subzone is fix at "1" and not visible.
The time switch information is expected from the same zone where
the thermostat is located (Residential).
If no time switch information is received from the same zone, the
thermostat will use the information received from the same apartment
but with room "1" A.1.1 (Office).
Example:
Commercial building
In a commercial building, the
time switch information is sent by
the RMB795 central control unit.
The zones are divided in so
called "Room groups" (e.g. 1...4),
where each "Room group" can
have an individual schedule. A
room thermostat in the same
"Room group" needs to have the
same Apartment Address.

In the case of a typical application, the individual RDF / RDG room thermostats
send their heat demand directly to the primary controller (in the above example to
the RMH760).

∂ This type of application can analogously be applied to refrigeration distribution

If function "Temporary setpoint" is enabled via parameter P69, then
after an operating mode change, the setpoint adjustments made
by the user and via communication object 23 will be dismissed and
the thermostat will be reset to the Comfort basic setpoint.
Note: Setpoints that have been changed via the local HMI may be
overwritten during a system startup from a central master
controller, e.g.RMB795.
The Comfort basic setpoint is stored in EEPROM (see section

3.14 Control parameters
A number of control parameters can be readjusted to optimize control performance.
This can be done on the thermostat via HMI or via commissioning / operating tool.
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, see page 53.
The control parameters are assigned to 2 levels:
∂ "Service level", and
∂ "Expert level" including communications, diagnostics and test.
The "Service level" contains a small set of parameters to set up the thermostat for
the HVAC system and to adjust the user interface. These parameters can be
adjusted any time.
Change parameters at the "Expert level" carefully, as they impact the thermostat’s
control performance and functionality.

6. Press + or – until "End" is displayed, and then press + and – simultaneously to
save the change and exit parameter entry mode.
The factory setting for the control parameters can be reloaded via parameter P71,
by changing the value to "ON", and confirming by pressing buttons + and –
simultaneously. The display shows "8888" during reload.

4. Handling
4.1 Mounting and installation
Mount the room thermostat 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
∂ Mount the room thermostat in a clean, dry indoor place without direct airflow
from a heating / cooling device, and not exposed to dripping or splash water.
∂ In case of limited space in the conduit box, use mounting bracket ARG70.3 to
increase the headroom by 10 mm.
Wiring
See Mounting Instructions enclosed with the thermostat.
M3171... [3], M3076.3 [3a]
∂ Comply with local regulations to wire, protection and earth the thermostat.
Warning!
No internal line protection for supply lines to external consumers (Q1, Q2,
Q3, Yxx)
Risk of fire and injury due to short-circuits!
∂ Adapt the line diameters as per local regulations to the rated value of the
installed overcurrent protection device.
∂ The AC 230 V mains supply line must have an external 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.
∂ Cables of SELV inputs X1-M/X2-M: Use cables with 230 V insulation, as 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. The maximum contact current
rating for the external switch should fulfill the overall sensing current of all
connected inputs.
∂ KNX communication cables (input CE+ / CE-): Use cables with 230 V
insulation, as the conduit box carries AC 230 V mains voltage.
∂ Disconnect from supply before opening the cover.
∂ When a KNX bus power supply is connected on the line with communicating
thermostats and Synco controller, the internal KNX power supply of the Synco
controllers must be switched off.

4.2 Commissioning
The room thermostats are delivered with a fixed set of applications.
Select and activate the relevant application during commissioning using one of the
following tools:
– Local DIP switch and HMI
– Synco ACS
– ETS
Set the DIP switches before snapping the front panel to the mounting plate, if you
want to select an application via DIP switches.
All DIP switches need to be set to "OFF" (remote configuration), if you want to
select an application via commissioning tool.
After power is applied, the thermostat resets and all LCD segments flash, indicating that the reset was correct. After the reset, which takes about 3 seconds, the
thermostat is ready for commissioning by qualified HVAC staff.
If all DIP switches are OFF, the display reads "NONE" to indicate that application
commissioning via a tool is required.
Each time the application is changed, the thermostat reloads the factory setting for
all control parameters, except for KNX device and zone addresses!
Connect the Synco ACS or ETS tools to the KNX bus cable at any point for
commissioning:
