- Page 2 Temperature control setpoint by delivering 2-position valve control commands or compressor output com- mands. With the RDF210, an external room temperature sensor (QAA32) or external return air temperature sensor (QAH11.1) can be used instead. The switching differential is 2 K in heating mode and 1 K in cooling mode (adjustable via parameters P08 and P09).
- Page 3 Operating modes The following operating modes are available: In Normal operation, the controller maintains the setpoint, which can be adjusted via Normal operation buttons. The fan can be set to automatic or manual fan speed: Low, medium or high. The setpoint setting range can be limited to a minimum (P05) and maximum (P06). This Tip! helps prevent the waste of energy, thus saving costs.
- Page 4 Control output Y12 delivers a control command which is inverted to the control command at output Y11 and which can be used for normally open valves. With the RDF210, the changeover between cooling and heating takes place either Heating / cooling...
- Page 5 Whenever the fan starts from standstill, it starts with speed 3 for 1 second in order to Fan start guarantee a safe fan motor start (to overcome inertia and friction) In Auto Timer mode, the default fan mode is automatic. The fan mode can be changed Fan in Auto Timer to manual fan speed.
- Page 6 The controller will leave the programmable timer setting mode if no button is pressed within 20 seconds. All changes made after the last press of button will not be saved. Press the button to sequentially review the 8 timers. View the timers Timers A1…A4 have the following default setting: Default timer setting Day/s...
- Page 7 External sensor input B1-M With the RDF210, a return air / external room temperature sensor or heating / cooling changeover sensor can be connected to terminal B1-M. The function of this sensor input is determined by parameter P22. Sensor input B1-M is not galvanically separated from the AC 230 V mains supply.
- Page 8 Using parameter P25, infrared remote control can be disabled. Control parameters With the RDF210 and RDF210.2, a number of control parameters can be readjusted to optimize the control performance. These parameters can also be set during operation without opening the unit. In the event of a power failure, all control parameter settings will be maintained.
