Multiple valves, parallel series regeneration system (System #6)
This system type may be used to build systems from 2 to 4 valves for NXT controller,
2 to 8 valves forNXT2. Only One water meter is required for the whole system.
During normal operation, the controllers of each valve display the time of day and the
volume of water remaining. The remaining volume is the total volume of the system.
The remaining volume displayed drops with water consumption to reach zero. When
this happens, if no other valve is regenerating, the lead valve starts regeneration while
sending out a regeneration lock out signal to all other valves of the system. If another
valve is regenerating, the valve will stay in service until the other goes back in service.
As soon as the lead valve finishes its regeneration cycle, the second valve starts
regenerating, then the third, etc. The regenerating valve keeps on sending a
regeneration lock out signal to all other valves of the system. A manual regeneration
can only be done on the lead valve and only if the others are not regenerating.
Automatic regeneration may be triggered by either volumetric mean or external dry
contact.
