At this setting the room sensor is only used as a display device 
without influencing the room temperature-related functions. The 
operation of the wall device is possible without restrictions.  

 

All system layouts that exclude room influence while the display of 
the actual room temperature is still required (in contrast to setting 
OFF). 

 

5.4.4 "Direct heating circuit" menu (UNMIXED CIRC), Pg. 92 

This function determines to what extent a deviation of the room 
temperature from the setpoint affects the control of boiler flow 
temperature. 

If there is no difference between the desired (TARGET) and the 
current (ACTUAL) room temperature, the direct heating circuit's 
flow temperature is controlled according to the set heating curve. 

If there is a difference between the room temperature and the 
setpoint, the heating curve is shifted parallel to the room 
temperature axis so that the deviation is compensated. The 
amount of the displacement depends on the setting of the room 
factor.
