Basic function of domestic hot water production
If the measured temperature value of the domestic hot water
falls below the
adjusted switching limit (5-0) and if the charge, released by a time program
or
a domestic hot water charge takes place. The domestic hot water set
point value can be affected by the following function/parameters:
•
Time program:
In principle the domestic hot water heating is connected with the heating time
program. It is to be noted that before providing its own domestic hot water
clock program the connection must be separated in the heating clock pro-
gram. Its own clock program is available for each heating circle (green/red).
•
Legionella protection:
The day for the activation of the legionella protection is selected with the para-
meter 3-9.
•
Frost protection function:
If the minimum system temperature falls below the switching limit adjusted to
10 °C around (parameter 5-0), the domestic water is heated on this tempera-
ture.
