Emission measurement can be terminated at any moment in 

advance with the 

 key. 

 

Safety temperature limiter check may be performed only by the 
technician 

 

By keeping the input button 

î

 pressed during an emission 

measurement, the integrated heat generator maximum 
temperature limit is bypassed and the heat generator remains in 
operation continuously until the safety temperature limiter (STL) is 
triggered. During the safety temperature limiter check, all the 
consumers are separated from the heat generator, i.e. any 
available mixed heating valve is closed and all the heating and 
hot-water loading pumps are stopped. The emission 
measurement is continued from the moment of termination with 
the previously saved remaining time. 

 

Safety temperature limiter check by the heating technician 

 

Release the input button. The emission measurement still active 

is stopped with the 

 key. 

 

Depending on the controller version, various outputs can be 
tested. This is not only a relay test, but a function test by means 
of which the hydraulic components are tested. The partially 
compulsory sequence of the switching procedures is considered 
here. 

After selecting the test function, the relevant relays can be 
switched one after the other by pressing the input button 

î

 in the 

specified switching sequence.
