6.2 Configuration
The function block is activated in the factory for plant types H3-x and H4-x. Always
preconfigured is a boiler with a 1-stage burner, boiler pump, boiler temperature and
return temperature sensor. For plant types H4-x, a mixing valve with 3-position actuator
for the maintained boiler return temperature is also preconfigured.
For more detailed information, refer to section
3.2 “Basic configuration”.

The basic configuration can be complemented and / or changed via “Extra configura-
tion”. Here, the 1-stage burner can be changed to become a 2-stage or modulating
burner, and shutoff valve, twin pump, flue gas temperature sensor and various check-
back signals and fault status signals can be added. Naturally, plant types H3-x can be
complemented by a mixing valve for the maintained boiler temperature.
