General note 4 Functions 4.1 Temperature control Setting of the control parameters (P01, etc., mentioned throughout the document) is described in section 4.15. 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.
4.2 Operating modes Select the thermostat's operating mode via the operating mode button on the unit or operating mode input (e.g. keycard occupancy sensor), when X1, X2, or D1 is set to 3 (P38, P40, P42). 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 thermostat maintains the room temperature setpoint which can be adjusted via the rotary knob.
4.3 Room temperature setpoints Comfort mode The setpoint in Comfort mode can be adjusted via the rotary knob. Setpoint limitation For energy saving purposes, the setpoint setting 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 2 limits P09 ≥ P10 • For heating or cooling applications (e.g.
4.4 Setpoints and sequences 4.4.1 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 electrical 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).
4.4.2 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.
4.5 Applications overview The thermostats support the following applications, which can be configured via DIP switches at the rear of the unit. Depending on the type of thermostat, on/off or modulating control outputs are available. Application (set via DIP switches 1…3) Heating or cooling • 2-pipe fan coil unit • Chilled / heated ceiling • 1-stage compressor 1) DIP switch Control output (set via DIP swi. 4 and 5) ON/OFF, PWM, 3-position T Product no.

Purge function Caution 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.

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. After the actuator reaches the position calculated by the thermostat, a waiting time of 30 seconds is applied to stabilize the outputs. This function is available with RDG100 and RDG100T only.
4.9 Fan control Different fan output signals are available depending on the thermostat type: Overview of fan outputs Control output Product no.

In automatic mode, the fan speed depends on the setpoint and the current room temperature.
1-speed / 3-speed fan The thermostat can control a 1-speed 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.

Note: Fan kick value “0” means the fan runs continuously in the dead zone. Fan kick value “OFF” means the fan does not run in the dead zone.
4.10 Multifunctional input, digital input The thermostat has 2 multifunctional inputs X1 and X2 and a digital input D1. A sensor type NTC like the QAH11.1 (AI, analog input) or a switch (DI, digital input) can be connected to the input terminals.
