When the temperature limit is exceeded the heat generator is 
disabled and inhibited permanently. It can only be unlocked by a 
reset in the "Fault Messages" menu. 

 

With the parameter set accordingly, the allowable temperature 
limit for the flue gas, according to specifications of the heat 
generator manufacturer, has to be entered as the reference value 
for the follow-up functions described above.  

 

Nominal flue gas temp. acc. to manufacturer data, plus 10 - 20 K

The system features two operating hour and burner start-up 
counters (one each for the 1st and 2nd stages). The display is 
output on the information level of the counter. 

The function of the operating hour counter can be set via a 
parameter. 

 

The operating hour counter is deactivated. 

 

If an operating hour counter is connected to the corresponding 
inputs of the controller (operating hour counter inputs), this value 
is called upon for counting. 

Otherwise, theoretical values are determined and included 
(switching times and switching frequency of the outputs).  

If a signal was detected once at the operating hour counter input 
and the operating hour counter signal does not follow the boiler 
demand, a fault message occurs. 

 

Functions such as AUTO, however a theoretical value is not 
determined. Only signals from burners are processed. 

 

The operating hour counter input can be used as a free counting 
input. A fault message does not arise if a signal is missing. 

 

Since the counter values are only stored in the permanent data 
memory once per day, counter values of the current day could be 
lost in case of a power failure.
