8 Directions for use
This is a control unit for a
Praher multiport valve with 6 positions for fully automatic filter
backwashing according to need, i.e. pressure and/or time. Operation of the Aquastar without
corresponding valve can cause damage to the electronics.
A filter pump connection is activated about 20 sec after the respective position is reached. The
dry running design guarantees safe operation.
The Aquastar must never be operated without a Praher V6 valve to avoid damage to the
device
Additional electrical connections are available:
Backwash position; rinse position; for series connection of several valves installed in series; for
interruption of a heater or a heat exchanger before cycle start; for a ball valve during the cycle.
ATTENTION! For relief of the sealing system the valve is shipped on
intermediate position and is not sealed! Prior to operation it has to be
electrically set to position “Filter”!
