When control is programmed as ALT A & ALT B signifying to PC board to operate an alternating system, factory default for reserve setting
is "AUTO" and hardness as 20 gpg and capacity to 90% of specified capacity on page 38-39. This allows 10% safety factor to maintain
good quality soft water at end of service run at high flows.
When programmed as an alternator there is not an option to program "OFF" for reserve, as this would cause regeneration on calendar
day override, defeating purpose of twin alternating system.
An added benefit of the alternating software is the option of the delayed rinse and fill. When set on, the last two steps of regeneration
(rinse & fill) are delayed until right before the unit comes on line. This pre-service rinse will minimize hardness and iron leakage from
resin due to a prolonged stagnant mode. This is only available when softening system is programmed as post fill. See page 16.
