advance with the key.

Safety check Safety temperature limiter check may be performed only by the technician

Function 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.

Application Safety temperature limiter check by the heating technician

Cancellation Release the input button. The emission measurement still active

is stopped with the key.

7.3.13.3Relay/function test

Function 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.
