Discharge to heating circuits 

Any excess heat is dissipated into the heating circuits. The set 
maximum temperature is not exceeded here. The intended room 
temperature may be exceeded for short periods. If the respective 
circuits are equipped with room stations, the thermostat function 
should be activated. 

 

 

Any excess heat is dissipated into the buffer tank, without 
exceeding the set maximum temperature. 

 

Only if parameter 8 variable input 1 = 16 - Flue gas sensor set in the 
"Hydraulics" menu. 

A flue gas sensor can only be connected to the variable sensor 
input VI 1. Due to the high temperatures involved, a PT 1000 
sensor is used for this purpose. The control device automatically 
evaluates the sensor data, which are different from the data 
supplied by the standard sensors. 

When a sensor fault is detected with the flue gas sensor active, 
and if flue gas monitoring was set for temporary disable or 
permanent inhibit (safety functions), there will be a heat generator 
switch-off in addition to the malfunction message. 

 

This function controls the necessary measures in case the flue 
gas temperature exceeds the allowable limit. 

 

Display of flue gas temperature only 

No follow-up function; the actual flue gas temperature is displayed 
in the Information display. 

 

Heat generator lock if limit value is exceeded for set time 

When the temperature limit is exceeded the heat generator is 
disabled for the set time and a fault message is sent.
