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 The thermostat sends the effective room operating mode on the bus. Room operating mode: State 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.
Operating mode via bus The operating mode can be changed via bus. Time schedule via bus Temporary extended Comfort mode via operating mode button The operating mode can be temporarily set from Economy to Comfort by pressing the operating mode button, if... – Economy was sent via bus – extended Comfort period >0 (parameter P68) The last intervention wins, either locally or via bus. The operating mode sent via bus can be overridden by all other interventions.
Operating mode switchover contact (window contact) (RDF301…) The thermostat can be forced into Economy mode (e.g. when a window is opened, when a presence detector signals "no one present", when the keycard of a hotel room is withdrawn, etc). The contact can be connected to multifunctional input X1, X2. Set parameter P38, P40 to 3. P02 is not relevant. User operations are ineffective and "OFF" is displayed if the operating mode switch over contact is active.
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. 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.
Example 1 (RDF301…) Operating mode switchover In room 1, the window is opened briefly, once in the morning, once in late afternoon and once at night (1). Only the opening in the morning has a direct impact on the effective room operating mode. During lunch break, the time schedule changes to Precomfort. The mode remains in Comfort as set by parameter "Transformation Precomfort" (P88 = 1).
Example 2 (RDF301…) Interaction of user operation (operating mode button) and central time schedule 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.
Example 3 (RDF600…) Application with "Window Contact", "Presence Detector" and central time schedule In room 3 operating mode Comfort is possible between 6:00 and 20:00, based on time schedule or occupancy period. Outside this time the operating mode remains in Protection. • • • • • • • • • Time schedule Room operating mode At 6:00 the central set the operating mode to Economy. (1) In the morning, as soon as the presence is detected (8:00 – 12:00), the operating mode will be switched to Comfort.
3.3 3.3.1 Comfort mode Room temperature setpoints 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 touch panel, 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.
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. Remote configuration All DIP switches need to be set to OFF (remote configuration, factory setting) to select an application via commissioning tool. Remote configuration, via commissioning tool (factory set) • Synco ACS • ETS DIP switches ON 1 2 3 The tools provide the applications described in section 3.4.

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).
Purge function 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.

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 Heating T °C 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).

3.6.7 Compressor applications For compressor applications, • set the corresponding basic application • disable the fan (P52) or set the fan speed (P53) The following applications are available: Application for compressor Set basic application 1-stage compressor for heating or cooling 1-stage compressor and electric heater (for cooling only: disable electric heater via P13) 1-stage compressor for heating and cooling 2-pipe See section 3.6.
3.6.8 2-pipe applications 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).
4-pipe applications 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.
3.7 Control outputs 3.7.1 Overview of control outputs Overview Different control output signals are available. They need to be defined during commissioning (see below). Control output Product no.

Synchronization 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.
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 according to the setting of parameters P15 (fan stage in dead zone Comfort on RDF600KN) and P60 (fan kick).

Fan operation in dead zone P15, Comfort mode (RDF600KN) 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).
Fan start delay (RDF600KN) To let the heating / cooling coil reach its temperature, the fan start can be delayed by a time period set via parameter P67. 31 81 D23 Y 1 0 T Q P67 T Note: This function (via parameter P67) is not implemented into RDF600KN SW version < V1.8. 48 / 92 Siemens Building Technologies RDF301, RDF301.50...
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.

In this case, the function must not be assigned to any local input X1, X2. See also section 3.6.
3.10 Handling faults 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 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.
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.
• 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]). Engineering and commissioning 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, RDF301.50H only) K NX Light and blinds as well as scenes are operated via switching groups. R The communication objects of the buttons need to be bound to a corresponding KNX actuator module.

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 51. The control parameters are assigned to 2 levels: • "Service level", and • "Expert level" including communications, diagnostics and test.
3.14.2 Parameter setting / download via tool Control parameters can be adjusted via bus either by parameter download during commissioning or during normal operation with a tool like ACS. ACS With the ACS tool, the parameters can be changed… – during commissioning via parameter download (all parameters) – during normal operation via Popcard (most of the parameters).
