8) Pump and 3 Way Valve Blockage Protection Function:
Blockage protection protects the pump against blockage in cases when the pump is not in use for a
long period. This function enables the pump to be operated for a few seconds in CH position when
the pump is not operated within the recent 24 hours.
The same feature is also valid for 3 way valve. 3 way valve protection protects against blockage by
enabling the changing of the direction of 3 way valve if it has not changed its direction in the recent
24 hours.
