3. Functions 3.1 Temperature control General note: Parameters Setting of the control parameters (P01, etc., mentioned throughout the document) is described in section 3.14. 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.
Note When an application program is downloaded to the Synco devices via ETS, the correct group addresses need to be downloaded as well, in order to display the time of day on the room thermostat (see Synco Knowledge Base - KB771). 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. KNX The thermostat sends the effective room operating mode on the bus.
3.2.1 Source for change of operating mode ACS Source Local operation via left button Bus command KNX 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.
Function if no time schedule is received via bus User profile for operating mode (selected via P02) P02 = 1: P02 = 2: Note Operating mode when activating function Function Comfort Comfort Comfort or Economy Comfort or Economy Extension Absence Extension Absence Operating mode during function Comfort Protection Comfort Economy Operating mode at the end of function Protection Comfort Economy Comfort Extension / Absence functions not available in protection mode Function with time schedule via bus Use
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.
Example 2 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. • • • • 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 rotary knob, or via bus from a remote device like a touchpanel, operating unit, etc. The last intervention always wins.
*) Note: SW < V1.20 For heating and cooling applications (e.g. 4-pipe): – P09 is the setpoint for cooling and P10 the setpoint for heating – The setpoint can not be adjusted via the rotary knob 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.

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, D1 is assigned with this function. KNX In the absence of the required information (e.g. due to problems with data communication, power failure, etc.
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 bus or via an external sensor / switch connected to X1, X2, or D1).
Living rooms: Up to 26 °C for long-time presence, up to 28 °C for short-time presence. Bath rooms: Up to 28 °C for long-time presence, up to 30 °C for short-time presence. Recommended values for P51: The table below shows the relation between parameter, temperature source and temperature display: OFF OFF 10...50 ˚C External temp. sensor available No Yes No Source for display of room temperature Built-in sensor External temp.
Dew point monitoring Dew point 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 dew point 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.
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 = heating sequence for el.
3.6.2 KNX 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.

3.6.8 2-pipe / 2-stage heating or cooling 2-stage heating or cooling On 2-stage applications, the thermostat controls 2 valves or compressors in heating or cooling mode or changeover (automatically or manually). "Cooling only" is factory-set (P01 = 1). Heating mode In heating mode, the 1st stage is activated if the acquired temperature is below the setpoint. The 2nd stage is activated if the acquired room temperature drops below "setpoint" minus "setpoint differential".
Modulating control: 3-position, PWM or DC 0...10 V The diagrams below show the control sequence of modulating PI control.
3.6.9 Chilled / heated ceiling and radiator applications For chilled / heated ceiling and radiator, • set the corresponding basic application according to section 3.
3.6.11 Setpoints and sequences 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).
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.

The diagrams below show fan speed control for modulating PI control. 3-speed fan control with modulating heating / cooling control (PWM, 3-pos or DC 0...
1-speed / 3-speed fan 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. Control sequence for DC 0...10 V fan (ECM) and DC 0...10 V valves (RDG160KN) When DC 0...10 V Fan and DC 0...10 V valve output control are selected, the fan switching points can be set via the following parameters: – P55: ECM fan max. output – P56: ECM fan min.
Fan kick P60, P61 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.
Clean fan filter reminder 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)). KNX The "Clean filter reminder" is reset when the operating mode is manually set to Protection and back.
3.9 Multifunctional input, digital input The thermostat has 2 multifunctional inputs X1 and X2 and a digital input D1. 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, P40 + P41 for X2, and P42 + P43 for D1. KNX The current temperature or state of the inputs X1/X2 and D1 is available on bus for monitoring purposes.
# 6 KNX Function of input Fault Description DI Monitor input (Digital) R 8 Monitor input (Temperature) Sensor input to monitor the state of an external sensor (e.g. QAH11.1) via bus. AI -- R 9 Supply air temperature limitation (RDG160KN only) 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).
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.

3.11.5 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 RDG 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.

The control parameters, ([Pxx] description) can also be adjusted and downloaded. Refer to section 3.14. 5.2 ACS ACS tool With the ACS tool, the RDG KNX thermostats can be commissioned (physical address, application, parameters). They can be operated or monitored via bus during normal operation. This Manual does not describe how the physical address is defined. Also, it only gives a brief overview of the main functionality of ACS. For more information, refer to the ACS online help.
The application and control parameters can be adjusted and downloaded. Column Line no. contains the parameter number as shown in the parameter table. Refer to section 3.14, control parameters. STOP Note! Some parameters have a different range in ACS than in the room thermostats. The thermostat does not accept changes that are outside its range. This can be observed online by the fact that a changed value jumps back to the original value.
Parameter settings in ACS Notes: ACS supports parameter settings even during normal operation. To change a control parameter, select Popcard, then Settings. • Make sure you have logged on with sufficient access right.
Plant diagram in ACS ACS offers plant diagrams for easy monitoring and operation of the thermostat. To start this application, select Applications, then Pant diagram.
