PWSRTA
For Watts alternator systems using PWSRTA valves there will be an option to delay the last two cycles of
regeneration (only "Rinse" and "Fill"). This feature splits the regeneration into two portions. The first portion
of the regeneration will start immediately and all programmed cycles before the "Rinse" and "Fill" cycles will
be performed. After all programmed cycles before "Rinse" and "Fill" are completed the control valve will
drive to the service position (displaying "Delayed Rinse + Fill Pending"). When the volume of the on-line
unit is depleted to 10% of its programmed capacity, the control valve will be triggered to finish the second
portion of the regeneration and complete the "Rinse" and "Fill" cycles and return to Service and be placed
into Standby mode, and wait to come on-line for service. Set to oFF to
deactivate this feature.
PWSRTA2
For Watts alternator systems using the PWSRTA2 valve, when NEXT is pressed after selecting ALT
A or ALT B, a display will allow the user to set the amount of pre-service rinse time for the stand by
tank just prior to returning to service. Set to oFF to deactivate this feature. With 1.0 set, the same
display appears and is set in a similar manner.

NOTICE
Watts Twin Alternator Operations
• Twin alternating systems can be programmed with a day override setting combined with the normal volume-based regeneration
programming. A twin alternating system in this configuration will then regenerate based on the volume used or the day override if there
is a period of low water usage.
• Twin alternating systems can be programmed as a time clock only based regenerating system. In this configuration, the days remaining
are counted only on the unit that is in service. The unit in Stand-by Mode only notes days in diagnostics, which results in time clock
only twin regeneration initiation.
• Twin alternating systems can be programmed for a delayed regeneration time. The system will allow an immediate transfer of the MAV
to switch tanks and place a fully regenerated unit in service once a unit becomes exhausted. The exhausted unit will then be placed into
Stand-by Mode and allowed to have a delayed regeneration at the pre-set time.
