" armer/Colder" menu
Here you can increase or reduce the room temperature. The supply line temperature
of the related heating circuit (5) will then be corrected by the value set here.
"Party" menu
Here you can enter the number of hours for which the heating system will adopt or
remain in the " anual day" operating mode. This applies only for the selected heating
circuit (5).
"Holiday" menu
Here you can enter the number of days on which you will be absent. The heating
circuit will adopt the " anual night" mode for the number of days selected here. Then
the heating circuit will return to the previously set operating mode. This applies only
for the selected heating circuit (5).
"Hot water" menu
Here you can increase or reduce the temperature of the hot water. This applies for all
heating circuits.
Reducing the temperature can save energy when only little or no hot water is
required. Increasing the temperature is useful when you need more hot water.
"Heating circuits" menu
Here you can change the heating circuit if more heating circuits are provided and
activated.
The "Comfort" menu can be set as the idle screen (standard screen) at:
•Program/Idle screen/Comfort menu.
MFC 1-6
This menu allows you to display and reset measurement values of the multi-function
controller. In this case the terminal designation precedes the designation for the sensor
(e.g. S1: Source). As in the "Solar circuit" menu item, you can also reset the minimum and
maximum values here.
