This parameter refers to the type of the heating system (floor, 
radiator or convector heating) and can be matched to the 
exponent of the respective heat distributor. Using its progressive 
characteristics, the set value determines the curve characteristics 
of the heating curve of the direct heating circuit and compensates 
for the losses in output in the low-temperature range with it. 

The following settings are recommend depending on the type of 
heating system: 

UFH 

Slightly progressive heating curves for floor or other 
area heating. 

RAD 

Progressive standard heating curves for all radiator 
heating with m-values between 1.25 and 1.35. 

CONV  Progressive heating curves for convector and 

baseboard heating. 

 

RAD (radiator 

systems) 

UFH 

(floor heating) with mixed heating circuits 

 

UFH, RAD, CONV 

 

The control device contains substantial error-notification logic. 
The error messages appear in continuous alteration with the basic 
display. Multiple errors that occur at the same time appear one 
after another in the order in which they occurred. The following 
types of error message exist: 

 

Sensor measured values that do not lie in the measurement 
range are evaluated as an interruption or short-circuit. They 
appear depending on the type and allocation with fault code 10 to 
20 and index 0 for short-circuit or 1 for interruption. 

 

These error messages evaluate the respective switching status. 
They appear depending on the type and allocation with fault code 
30 to 40 and index 0, 1 or 2.
