Use 

For controlling the room temperature in individual rooms and zones that are 

  heated or cooled with 2-pipe fan coil units 

  cooled with a single compressor in DX type equipment 

 
The controller controls 

  a 3-speed fan 

  either a valve actuator in a 2-pipe system, or 

  a 1-stage compressor in DX type equipment 

 
Suitable for use in systems with 

  automatic heating / cooling changeover (RDF110) 

  continuous heating or cooling mode (RDF110) 

  manual heating / cooling changeover (RDF110.2) 

 

Functions 

  Changeover between heating and cooling mode is either automatic by a QAH11.1 

changeover cable temperature sensor or manually 

  Maintenance of room temperature either with integrated temperature sensor or 

external room / return air temperature sensor (only with RDF110 and RDF110/IR) 

  Selection of operating mode with an external changeover switch (only with  

RDF110 and RDF110/IR) or with the operating mode button 

 on the controller 

  3-speed fan control (automatic or manual) 

  Output for 2-position (on / off) valve actuator or 1-stage compressor 

  Optional with infrared remote control (only with RDF110…/IR) 

 

Controller 

The controller acquires the room temperature via its built-in sensor and maintains the 
setpoint by delivering 2-position valve control commands or compressor output 
commands. With the RDF110, 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). 

The display shows the acquired room / return air temperature or the setpoint of the 
current operating mode. This can be selected via parameter P18. Factory setting is 
display of the current room temperature. 
The heating   and cooling   symbols on the display show the status of the fan coil. 
This means that the symbols are also shown while the controller operates in the neutral 
zone. 
If required, room temperature and setpoint can also be displayed in °F in place of °C by 
changing parameter P17. 

Operating modes 

The following operating modes are available: 
In Normal operation, the controller maintains the setpoint, which can be adjusted via 

the     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 

helps prevent the waste of energy, thus saving costs.
