R0808 

If this button is pressed and held longer than 5 s in the basic 
display, the controller is switched to manual mode. In this 
operating mode, the required heat generator temperature is 
specified manually with the input button 

î

 according to the 

respective heating need.  
A controller set to manual mode has no effect in heat circuit 
expansion.  

The heat generator setpoint is set between the minimum and 
maximum heat generator temperatures and appears flashing at 
the bottom left-hand side. The current heat generator temperature 
appears statically on the right-hand side in the basic display. The 
set switching differential corresponds to the value of automatic 
control and is symmetrical to the set value. 

 

Controller malfunctions (emergency operation), errors 

 

The maximum heat generator temperature limit is paramount to 
the heat generator switching differential and stops the heat 
generator in case of exceedance. 

With control devices operated purely as a heating circuit 
expansion, the setting of the temperature has no effect. 

The last value to which the control device adjusted the heat 
generator temperature appears as a recommendation. 

 

Press 

 button or 

 button, to return to the last selected 

operating mode.
