CAUTION!
A heating system that is not frost-protected can freeze
in cold weather and be damaged.
●
Drain the water out of the heating system if there is
a danger of frost.
●
If the heating system is not drained, the power
supply must be ensured and the main switch must
remain switched on if there is a danger of frost.
In this mode, the ROTEX HPSU compact is shifted to the stand-
by mode. The frost-protection function remains in place. In order
to maintain this function, the system must not be disconnected
from the mains!
If the outdoor temperature is below the parameter value [T-Frost
Protect] the integrated heating circulation pump is switched on in
order to prevent the heating system from freezing.
All controllers integrated into the RoCon-system via the CAN bus
are also switched at a higher level to the operating mode
"Standby".
