How SmartPlus™ works
The SmartPlus circulator has a mode select
toggle switch that allows for 2 operation
modes. “Pulse” or “Smart” mode can be
selected using the toggle switch located
on the capacitor base mounted electronic
control board. A yellow LED indicates which
mode is selected. All operation is automatic,
no manual timer or temperature setting is
required.
Pulse Mode
When set for Pulse mode, the
SmartPlus circulator will run for
150 seconds every 10 minutes to
maintain hot water at all xtures.
Smart Mode
When set for Smart mode, the
circulator will run in Pulse mode as
above for the rst 7 days. During
the rst 7 days, the SmartPlus will
monitor and record the homes hot
water usage pattern. For the next
7 days, the SmartPlus will use the
preceding week’s usage pattern to
cycle the pump. This process will
be repeated every 7 days.
Features and Benets
Vacation Function — After 36 hours of
inactivity the pump will automatically TURN
OFF and remain o until hot water usage is
detected again.
Exercise Function — While in vacation mode
the pump will cycle on once every 7 days and
run for 10 seconds to prevent any corrosion or
scale buildup.
