Note
Your system is factory-configured as a "Detached
house". All heating circuits in your system are
assigned to a house or home.
If you want to assign your heating circuits to individual
homes, your contractor can change this setting to
"Apartment building". The "Apartment building" setting
allows you to select the heating circuits, and therefore
the homes, to which the "Holiday program" applies.
