3.2 Variations
3.2.1 Solar supported water heating
In the system example, the solar controller is operated via the WCM-FS, address
#1.
The external sensor is connected to WTC address #A.
DHW operation is carried out via WTC address #A.
The solar controller is operated via the FS which, according to the address setting,
has the functions DHW program, time master and circulation program. The following
addresses are possible: Control centre#L, WTC-HC#1, WTC-HC#1 + EM-HC#2
and EM-HC#2. The WTC should be set to address #A.
