3. Functions 3.1 Room temperature control General note: Parameters Information for setting the control parameters (e.g. P01) is described in section 3.14. Room temperature control The thermostat acquires the room temperature using its 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 the heating and/or cooling equipment.
Time of day via bus can be displayed on the 2nd line of the LCD display on the thermostat by setting P07 to either 3 or 4. The display is either in 12- or 24-hour format. Time of day via bus The information can be received from a Synco controller with time master functionality or any other KNX device if the corresponding communication object is bound.
When you touch OFF, the thermostat changes to ON first and then returns to Comfort or Economy mode. Then it displays the setpoint adjustment screen. Touch +/– to adjust the room temperature setpoint. Notes: · · · In Economy mode, the icon does not display since the setpoint is not adjustable. In Protection mode, both the and icons do not display since both setpoint and fan speed are not adjustable. On universal applications (P52 = 0), the icon does not display.
· the window contact is active (open window) · "Window state" is sent using the bus, e.g. from a KNX switch. See note*). Note: *) Refer to section 3.2.1 for details regarding the window contact and presence detector. 17 / 94 Siemens Smart Infrastructure RDF800KN..
3.2.1 Source for change of operating mode ACS Source Local operation using operating mode icon Bus command Room operating mode Influencing the operating mode The operating mode can be influenced in different ways. The source of the effective room operating mode state can be monitored using the "Cause" diagnostic data point in the ACS tool, bus operator unit RMZ792-B or web server OZW772.
Auto Timer mode with time scheduler using the bus If a time scheduler is available, e.g. from the central control unit, Auto Timer mode is active. The thermostat automatically changes between Comfort and Economy mode according to the time scheduler using the bus. The display shows the Auto Timer mode icon . Touch the operating mode icon to change to another operating mode.
The “window contact” function is also available using the KNX signal "Window state", e.g. from a KNX switch. Room operating mode: Window state Note: Only one input source can be used, either a local input X1/X2 or the KNX bus. User operations are ineffective and OFF is displayed if the operating mode “window contact” is active, or if "Window state" is sent using the bus.
3.2.2 Communication example The following example shows a typical application of a central time scheduler in conjunction with local control of the room operating mode. The room operating mode in the room of a building is determined by the time scheduler. Window contact and presence detector are fitted in this room.

3.5 Heating/cooling changeover using bus Additional functions The heating/cooling changeover information can only be received using the bus, if the control sequence is set to automatic heating/cooling changeover (P01 = 3), and no local input X1/X2 is assigned with this function. When the required information is missing (e.g. due to problems with data communication, or a power failure), the thermostat operates in the last valid room operating mode (heating or cooling).
Manual heating/cooling changeover If manual heating/cooling changeover is set (P01 = 2), heating/cooling mode cannot be changed using the bus, changeover sensor or switch; it will remain in the manually selected mode. External/return air temperature sensor The thermostat acquires the room temperature through its built-in sensor, external room temperature sensor (QAA32), or external return air temperature sensor (QAH11.1) connected to multifunctional input X1 or X2.

3.6 3.6.1 Control sequences Sequences overview using P01 (RDF800KN.., RDF800KN/VB only) The main control sequence (such as the water coil sequence of the fan coil unit) can be set via P01. The following sequences can be activated in the thermostats (each without or with auxiliary heating). The available sequences depend on the application (via the DIP switch, see section 3.4).
3.6.2 Application mode The behavior of the thermostat can be influenced by a building automation and control system (BACS) via the bus using the "Application mode" command. Application mode With this signal, cooling and/or heating mode can be enabled or disabled. Application mode is supported in LTE mode and S-mode. The RDF800KN../RDF800KN/VB/RDD810KN.. room thermostats support the following commands: No.
Heating OR cooling With 2-pipe applications, the control sequence state is determined by the application mode (see section 3.6.3) and by the state of the heating/cooling changeover signal (using the local sensor or the bus), or fixed according to the selected control sequence (P01 = heating (0)/cooling (1)).
3.6.3 2-pipe fan coil unit (RDF800KN.., RDF800KN/VB only) On 2-pipe applications, the thermostat controls a valve in heating/cooling mode with changeover (automatically or manually), heating only, or cooling only. Factory setting is “Cooling only” (P01 = 1). On/Off control Control sequence On/Off output The diagrams below show the control sequence for 2-position control.
3.6.4 Heating or cooling with auxiliary heater 2-pipe fan coil unit with electric heater (RDF800KN.., RDF800KN/VB only) 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 electric heater enabled (P13).
On/Off control Control sequence ON/OFF output The diagrams below show the control sequence for 2-position. Heating mode Cooling mode (automatic changeover = heating or heating only) (manual/auto.
3.6.5 4-pipe fan coil unit (RDF800KN.., RDF800KN/VB only) Heating and cooling On 4-pipe applications, the thermostat controls 2 valves in heating and cooling mode, heating/cooling mode by manual selection (P01 = 2), or heating and cooling mode with changeover. Heating and cooling mode (P01 = 4) is factory-set. On/Off control The diagrams below show the control sequence for 2-position control.
3.6.7 Compressor applications (RDF800KN.., RDF800KN/VB only) For compressor applications, proceed as follows: 1. Set the corresponding basic application 2. Disable the fan (P52) or set the fan speed (P53) The following applications are available: Application for compressor Set basic See section application 1-stage compressor 2-pipe 3.6.3 for heating or cooling 1-stage compressor and electric heater 2-pipe and electric 3.6.

3.7 Control outputs 3.7.1 Overview of control outputs Different control output signals are available. They must be defined during commissioning (see below). Control output Product no. RDF800KN.., RDF800KN/VB 2-position 2-position PWM Y1, Y2 (2 x SPST) Q11, Q12, Q14 (1 x SPDT) RDD810KN/NF *) On/Off control signal (2-position) Overview 3-position DC 0…10 V --- Y1, Y2*) (1 x / ) --- --- --- --- Only applies to 2-pipe applications.
Synchronization · · · Heating output control signal (2-position) RDD800KN/NF only When the thermostat is powered up, a closing command for the actuator running time + 150% is delivered to ensure that the actuator fully closes and synchronizes to the control algorithm. When the thermostat calculates either the fully closed or fully open position, the actuator's running time is extended + 150% to ensure the right actuator position is synchronized to the control algorithm.
3.8 Fan control (RDF800KN.., RDF800KN/VB only) The fan operates in automatic mode or at the selected speed in manual mode. In automatic mode, the fan speed depends on the setpoint and the current room temperature. When the room temperature reaches its setpoint, the control valve closes and the fan switches off or stays at fan speed 1 according to the setting of P15 (fan stage in dead zone Comfort) and P60 (fan kick).
3-speed fan control with modulating heating/cooling control The individual switching points for ON of each fan speed can be adjusted via P55…P57. The fan speed switch off point is 20% below the switch-on point. The diagrams below show fan speed control with modulating PI control.
Fan operation in dead zone (fan kick) 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 filter reminder Fault information The "Clean filter reminder" function counts the fan operating hours and displays message " FIL" to remind the user to 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 using P62 (default = OFF (0)). The "Clean filter reminder" function can be removed using +/ – when viewing alarms on the INFO page.
3.9 Multifunctional input, digital input The thermostat has two multifunctional inputs X1 and X2. An NTC type sensor, such as 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 using P38 or P39 for X1 and P40 or P41 for X2. The current temperature or the state of inputs X1 or X2 is available on bus for monitoring purposes. The parameters can be set to the following values: No.
No. 5 Function of input Enable electric heater Enable electric heater 6 Description Digital input to enable/disable the electric heater using remote control. Enabling the electric heater is also possible using the bus. In this case, the function must not be assigned to local input X1 or X2. See section 3.2.1.

3.10 Handling faults Room temperature out of range When the room temperature is out of the measuring range (that is, above 49 °C or below 0 °C), the limiting temperature flashes. 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 the measuring range.
