In single duct applications with radiator or floor heating, the thermostat controls a 
valve plus an auxiliary electrical heater. Parameter P01 is not available. 

The output signal for the air flow can be limited to a minimum and maximum value 
if required (see section 4.6 "additional features"). 

 
The air flow starts to rise when the acquired room temperature is above "setpoint" 
+ "dead zone".  
The radiator receives an ON command when the acquired room temperature drops 
below “setpoint” – “dead zone” (= “setpoint for radiator”). 

 

Note: “Setpoint for radiator” is limited by parameter “Maximum heating setpoint” 
(P10). 

 
The radiator sequence can also be used  for floor heating.  
The "Floor heating limitation function" is described on page 15.
