10.3 Description of the service functions
10.3.1 First service level
Service function 1.A: Maximum space heating output
Some gas supply companies offer a performance-dependent basic
price.
The output can be limited in percent between the minimum and
maximum nominal output to suit the specific heat demand.
Even if the heating output has been limited, the maximum nominal
output is still available for DHW generation.
▶ Select service function 1.A.
▶ Select heat output in MBH (kW) and determine associated setting in
percent (%).
▶ Enter the setting ( Chapter 10.1).
▶ Save the setting ( Chapter 10.1).
▶ Record the set heat output in the commissioning log ( page 60).
▶ Exit the service functions.
The display returns to the supply temperature.
The factory setting is the maximum nominal output: U0 (100 %).
Service function 1.b: Maximum DHW output
The hot water output can be adjusted between the minimum and
maximum DHW outputs to suit the heat transfer capacity of the DHW
tank coil.
▶ Select service function 1.b.
▶ Select the DHW output in MBH (kW) and determine the associated
setting in percent (%).
▶ Enter the setting ( 10.1).
▶ Save the setting ( 10.1).
