Frost protection

Frost protection measures are taken when the outdoor temperature falls below the Frost pro-
tection limit. The switching differential to cancel the frost protection measures is always 1 °C.
4
Frost protection program I (restricted frost protection): frost protection measures are taken
only when all heating circuits in the system are in stand-by mode. The circulation pumps
are automatically switched on and their flow temperature set points are adjusted to
10 °C. The circulation pump in the DHW circuit is automatically switched on only when
the stand-by mode has been adjusted at the rotary switch in all heating circuits. Never-
theless, the storage tank is always recharged to 10 °C if the storage tank temperature
falls below 5 °C.
4
Frost protection program II: the heating circuit circulation pumps are always switched on
automatically. The flow temperature set points of all heating circuits currently in stand-by
mode are set to +10 °C. In the DHW circuit, the circulation pump is always activated. If
the storage tank temperature falls below +5 °C, the storage tank is recharged to +10 °C.
