RDF600 – the room thermostat that allows you to set the ideal room temperature you want.  

The thermostat provides Comfort mode, Economy mode and Protection.  

The fan operates either in automatic mode or at the selected speed when using manual mode.  

You can either rely on the factory settings or make adjustments that suit your individual needs.

Press  +  or  - to increase or decrease the current room temperature setpoint for 
Comfort mode. The thermostat changes to Comfort   .  
The setting range is from 5...40 °C, unless limited by parameters P09 and P10. 

 

 

 

 

 

 

Press the   button until you reach the desired fan mode. 
In  Auto mode, the fan speed is automatically selected by the thermostat and 
depends on the setpoint and the actual room temperature. When the room 
temperature has reached the setpoint, the fan is switched off (factory setting) 
In  manual mode the fan operates independently and always runs at the same 
speed: Low, medium or high. 
Low fan speed 
Medium fan speed 
High fan speed 

For a single-speed fan, the mode can be changed between

The thermostat can be set to Economy mode either via pressing the operating 
mode button    if enabled (see parameter P02), or via an external contact such 
as window switch, key card switch etc.  
If the external contact is activated the thermostat changes from Comfort mode or 
Protection to Economy mode. Any operation by the user has no influence. 

In Economy mode, the automatic fan control is active.

cooling only or heating only, no changeover is possible (see parameter P01)
