Y11 and which can be used for normally open valves. Heating / cooling With the RDF110, the changeover between cooling and heating takes place either mode automatically via a heating / cooling changeover sensor or a remote changeover switch. - Page 4 With the RDF110.2, when pressing the heating / cooling changeover button , the controller will change from heating to cooling, or vice versa. Minimum output The minimum output on time and off time of Y11 can be adjusted from 1…10 minutes on time / off time Y11 via parameters P15 and P16.
- Page 5 External sensor input B1-M With the RDF110, 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 6: Error Handling
Should both the external and internal sensor fail, the display will flash “Err” to call the user‘s attention. Infrared remote control The RDF110/IR and RDF110.2/IR have an infrared receiver built in. Together with the IRA210 infrared remote control, the following operations can be performed from a remote location: •... -
Page 7: Control Parameters
Control parameters With the RDF110 and RDF110.2, 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. - Page 8 Control parameters of the RDF110 and RDF110.2 Para- Meaning Setting range Factory meter setting Setpoint of heating in Economy (Energy saving) mode 16 °C OFF, 5 °C…Wcool (Wheat Economy (Energy saving) Setpoint of cooling in mode 28 °C OFF, Wheat …40 °C...
