3. Functions 3.1 Temperature control General note: Parameters Setting of the control parameters (P01, etc., mentioned throughout the document) is described in section 3.13. Temperature control 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.
3.2 Operating modes The thermostat's operating mode can be influenced in different ways (see below). Specific heating and cooling setpoints are assigned to each operating mode. K NX R Room operating mode: State The thermostat sends the effective room operating mode on the bus. The following operating modes are available: Auto Timer In Auto Timer mode the room operating mode is commanded via bus.
3.2.1 Source for change of operating mode ACS Source Local operation via operating mode button Bus command K NX R Room op. mode The operating mode can be influenced by different interventions. The source of the effective room operating mode state can be monitored using the "Cause" diagnostic data point in the ACS tool, operator unit RMZ792 or web server OZW772 / 775.
Auto Timer mode with time schedule via bus If a time schedule via bus is present, e.g. from central control unit, then the Auto Timer mode is active. The thermostat automatically changes between Comfort and Economy according to the time schedule via bus. The display shows the Auto Timer mode symbol along with the symbol for the effective room operating mode (Comfort or Economy ). By pressing the operating mode button, you can change to another operating mode.
Temporary timer to extend the Comfort mode 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.
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.
Interaction of user operation (operating mode button) and central time schedule Example 2 In room 2, the window is opened briefly, once in the morning and once at night (1). Only the opening in the morning has a direct impact on the effective room operating mode. With the operating mode button, the operating mode can be changed between OFF and Auto or temporary Comfort extension respectively. Time schedule Room operating mode During lunch break, the time schedule changes to Precomfort.
Comfort mode 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.
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 (Economy or Protection) is set to OFF, the thermostat does not control the room temperature in the corresponding mode (heating or cooling).
3.3.
General notes: 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 Notes on setpoint adjustment (LTE mode with Synco only) 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 a
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 tool offers the applications printed in bold text (basic applications). For universal applications (chilled ceiling, etc.), refer to section 3.6.6.

3.5 Additional functions Heating / cooling changeover via bus The heating / cooling changeover information can be received via bus. This is only possible if the control sequence is set to automatic heating / cooling changeover (parameter P01 = 3) and no local input X1, X2 is assigned with this function. K NX In the absence of the required information (e.g. due to problems with data communication, power failure, etc.), the thermostat operates in the last valid room operating mode (heating or cooling).
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 “Floor temperature limitation” function influences the outputs listed in the table below: “Floor temp. limit” function has impact on Application Output Y11 2-pipe H/C valve 2-pipe & el heater H/C valve 4-pipe Output Y21 El heater Heating valve Cooling valve Heating (P01 = 0/2/3) Cooling Heat. and cool.
3.6 Control sequences 3.6.1 Sequences overview (setting via parameter P01) The main control sequence (i.e. the water coil sequence of the fan coil unit) can be set via parameter P01. The following sequences can be activated in the thermostats (each without or with auxiliary heating). The available sequences depend on the application (selected via DIP switch, see section 3.4). Parameter P01 = 0 P01 = 1 P01 = 2 P01 = 3 P01 = 4 T Sequence T °C T °C Heating Cooling *) 2-pipe with el.
3.6.2 K NX Application mode The behavior of the thermostat can be influenced by a building automation and control system (BACS) via bus with the command “Application mode”. With this signal, cooling and/or heating activity can be enabled or disabled. Application mode is supported in LTE mode and S-mode.
ACS Heating OR cooling The state (heating or cooling) of the thermostat can be monitored with the ACS tool (diagnostic value “Control sequence”). The last active mode is displayed when the thermostat is in the dead zone or temperature control is disabled. With a 2 pipe application, the control sequence state is determined by the application mode (see section 3.6.
3.6.3 2-pipe fan coil unit On 2-pipe applications, the thermostat controls a valve in heating / cooling mode with changeover (automatically or manually), heating only, or cooling only. Cooling only is factory-set (P01 = 1). ON/OFF control The diagrams below show the control sequence for 2-position control.
3.6.4 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 auxiliary 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.
ON/OFF control The diagrams below show the control sequence for 2-position. Heating mode Cooling mode (automatic changeover = heating or heating only) (man. / auto.
3.6.5 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).
The diagrams below show the control sequence for 2-position control.

3.6.6 Chilled / heated ceiling and radiator applications For chilled / heated ceiling and radiator, set the corresponding basic application disable the fan (P52) The following applications are available: Application for chilled / heated ceiling, radiator Chilled / heated ceiling with changeover Chilled / heated ceiling & el heater (cooling only: disable el heater via P13) Chilled ceiling and radiator 3.6.7 Set basic application 2-pipe See section 3.6.
3.6.8 Setpoints and sequences On changeover applications, the Comfort setpoints for heating and cooling sequence are the same (w). 2-pipe applications 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).
On 4-pipe applications, the Comfort setpoint (w) is in the middle of the dead zone, between the heating and cooling sequence. 4-pipe applications 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.
Overview of control outputs 3.7 Control outputs 3.7.1 Overview Different control output signals are available. They need to be defined during commissioning (see below). Control output 2-position Product no. RDF301, RDF301.50, Y11, Y21 RDF600KN (2 x SPST) *) Only on 2-pipe application Note ON/OFF control signal (2-position) 2-position PWM 3-position DC 0…10 V --- Y11, Y21 *) (1 x / ) --- In the ACS tool, Y11 and Y21 are called Y1 and Y2.
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. Note In the tool, the parameter is called "Output Y1 / Y2", not Y11 / Y21). 40 / 82 Siemens Building Technologies RDF301, RDF301.
3.8 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: RDF600KN fan Off in dead zone RDF301...

A 1-speed fan is connected to terminal Q1, a 3-speed fan to terminals Q1, Q2 and Q3.
Fan overrun for electric heater Fan failure When the electric heater is switched off, the fan overruns for 60 seconds (parameter P54) to avoid overtemperature of the electric heater or prevent the thermal cutout from responding. 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).
3.9 Multifunctional input, digital input The thermostat has 2 multifunctional inputs X1 and X2 An NTC type sensor 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 + P39 for X1 and P40 + P41 for X2. K NX The current temperature or state of the inputs X1/X2 is available on bus for monitoring purposes.
# 6 K NX Function of input Fault R Fault information K NX R 7 Monitor input (Digital) R 8 Monitor input (Temperature) X1, X2 (Digital) K NX X1, X2 (Temp.) Description Digital input to signal an external fault (example: dirty air filter). If the input is active, “ALx” is displayed and a fault is sent on the bus. See also section 3.11.8. (Alarm x, with x = 1 for X1, x = 2 for X2). Note: Fault displays have no impact on the thermostat's operation. They merely represent a visual signal.
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.
Engineering and commissioning 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.
The zones to be defined are as follows: Geographical zone (space zone) Zone in which an RDF KNX thermostat is physically located. Other room-specific devices may also be located in this zone. (Apartment . Room . Subzone) Apartment = ---, 1...126 Room = ---, 1...63 Subzone = fix 1 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.
3.11.4 Example of heating and cooling demand zone The building is equipped with Synco controls on the generation side and RDF / RDG thermostats on the room side. Konnex TP1 RMH760 Controller 1 RMB795 Controller 3 Controller 2 RDF... Controller 4 RDU... Controller 5 RDG...
3.11.5 Send heartbeat and receive timeout In a KNX network, S-mode and LTE mode communication objects can be exchanged between individual devices. The Receive timeout defines the period of time within which all the communication objects requested from a device must have been received at least once. If a communication object is not received within this period, a predefined value is used.
3.11.8 Fault function on KNX If a fault occurs (e.g. digital fault input, dew point, communication configuration, etc.) then a fault will be sent on the bus. An RDF thermostat listens on the bus and sends its fault when the fault has the highest alarm priority. This ensures that the management station does not miss any alarms. If alarms occur at the same time, the alarm with the highest priority will be first displayed and sent on the bus.
3.11.9 KNX switching groups (RDF301.50 only) K NX R Buttons ... Light and blinds as well as scenes are operated via switching groups. The communication objects of the buttons need to be bound to a corresponding KNX actuator module. 5 1 3 2 4 1, 2 Buttons of switching group left (1) 3, 4 Buttons of switching group right (2) 5 Display for indication while pressing buttons RDF301.50 has 2 switching groups with a pair of button each, which can be configured via ETS.
