General note 4 Functions 4.1 Temperature control The setting of he control parameters (P01 etc., mentioned throughout the document) is described in section 4.14. The controller 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 issuing actuator control commands to heating and/or cooling equipment.
4.2 Operating modes Select the controller's operating mode via operating mode button on the controller or operating mode input (e.g. keycard occupancy sensor, when X1 or X2 set to 3 (P38, P40)). A corresponding setpoint is used to maintain the room temperature at the desired level depending on the active operating mode. The following operating modes are available: Comfort mode In Comfort mode, the controller maintains the setpoint which can be adjusted via the +/- buttons.
4.3 Room temperature setpoints Comfort mode The setpoint in Comfort mode can be adjusted via the +/- buttons. Setpoint limitation For energy saving purposes, the setpoint adjusting range can be limited to minimum (P09) and maximum (P10). P09 < P10 · If the minimum limit P09 is set lower than the maximum limit P10, both heating and cooling are adjustable between these two limits. P09 ≥ P10 · For heating or cooling applications (e.g.
4.4 Applications The controller supports following applications, which can be configured by DIP switches on the inner side of the controller front panel.

Compressor-based application Use with one 1-stage compressor for heating and cooling, or cooling only, or heating only. Universal applications Thanks to a flexible fan control, the RDF3xx / RDF4xx can also be used in universal applications, e.g. fan coil-based cooling and floor heating, or chilled ceiling and electrical heater etc. See also section 4.8 “Fan control”. 4.5 Automatic H/C changeover Additional features The water temperature acquired by the changeover sensor (QAH11.1 + ARG86.
Avoid damage from moisture 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 to avoid damage from moisture due to a lack of air circulation. See also section 4.8 “Fan control”, under “Fan kick function”. Minimum output on-time/off-time Limit the on/off switching cycle to protect the compressor and reduce wear and tear.
4.6 Control sequences The controller can be used in systems featuring: · · · · Heating or cooling mode (P01=0 or P01=1) Manual heating/cooling changeover (P01=2) Automatic heating/cooling changeover (P01=3) Heating and cooling mode (e.g. 4-pipe system) (P01=4) The relevant modes are available and can be adjusted via commissioning parameter “Control sequence” P01, depending on the selected application. Sequence Parameter Mode P01 = 0 Heating mode P01 = 1 Cooling mode *) 2-pipe with el.
4.6.1 2-pipe fan coil unit On/off output Heating or cooling In 2-pipe applications, the controller controls a valve in heating/cooling mode with changeover (automatic or manual), heating only mode, or cooling only mode. Cooling only is factory set (P01=1). Control sequence on/off output The diagram below shows the control sequence for on/off (2-position) control.
4.6.2 2-pipe fan coil unit with electrical heater Heating or cooling with electrical heater In 2-pipe applications with electrical heater, the controller controls a valve in heating/cooling mode with changeover, heating only mode, or cooling only mode plus auxiliary electrical heater. Cooling only is factory set (P01=1) with enabled electrical heater (P13). Electrical heating, active in cooling mode In cooling mode, the valve receives an OPEN command if the acquired temperature is above the setpoint.
Note For better temperature control performance with 2-pos electrical heater, we suggest to set the switching differential heating (P30) to 1K. The diagram below shows the control sequence for continuous PI control. Control sequence modulating output Heating mode Cooling mode (automatic changeover=heating or heating only) (man. /auto.
4.6.3 4-pipe fan coil unit In 4-pipe applications, the controller controls two 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 selection The heating or cooling output can be released via operating mode selector button if parameter P01 is set to manual (P01=2).
The diagram below shows the control sequence of a continuous PI control.
4.7 Overview of control outputs Control outputs Different control output signals are available depending on the controller type. Control output on/off Type reference RDF300… RDF400… RDF340… RDF600 RDF600T 3-position Y11, Y21 (2) Y11, Y21 (2) Y11/Y21 (1) Y11/Y21 (1) Y11, Y21 (2) Y11, Y21 (2) Y11/Y21 (1) Y11/Y21 (1) DC 0…10 V Y10, Y20 (2) ( ) Number of outputs on/off control signal (2-position) The valve or compressor receives the OPEN/ON command via control output Y11 or Y21: 1.
4.8 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,: · RDF600... fan Off in dead zone · RDF3..., RDF4...
Fan operation as per heating/cooling mode, or disabled Fan operation can be limited to be active only in cooling or heating mode, or even totally disabled via control parameter “Fan operation” P52. When fan operation is disabled, the fan symbol on the display disappears and actuating the fan button has no influence. This function allows for using the controller in universal applications such as floor heating with fan coil cooling etc.
Clean fan filter reminder The clean fan 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 controller operations, which continues to run normally. The service interval can be set via parameter P62. The clean filter reminder is reset when the operating mode is manually set to Protection respectively .
4.9 Multifunctional input The controller offers two multifunctional inputs X1 and X2. A sensor of type NTC like QAH11.1 (AI) or a switch (DI) can be connected to the input terminals. The functionality of both inputs can be configured via parameters P38 for input X1 and P40 for input X2. # 0 1 Function of input X1/X2 Not used External/Return air temp. 2 Heat/cool changeover 3 Operating mode switchover 4 Dewpoint monitor 5 Enable electrical heater 6 Alarm Description No function.
4.10 Auto Timer (RDF400… / RDF600T only) The controller provides an Auto Timer mode with 8 programmable timers. Each timer can be assigned to one or several days. In this mode, the controller automatically changes over between Comfort and Economy mode as per the preprogrammed timers. Auto Timer for Comfort mode Set timers Auto Timer for Economy mode Each timer has a Comfort mode start and end time that can be applied to one or several weekdays.
3. Symbol flashes. Press + or - to select or clear each day and go to the next day. Confirm the actual timer settings by pressing and go to the next timer.
