MixiMizer
TM
- mixing reset pump
The Grundfos MixiMizer
TM
is a fully integrated
injection mixing pump utilizing indoor/outdoor control.
Appropriate water temperature will be supplied to your
mixing loop through adjustments in pump speed based
on outdoor temperature and supply/return piping
sensors.
Equipped with a weather responsive controller, also
known as indoor/outdoor controller or reset controller,
the MixiMizer
TM
automatically calculates and controls
mixed water temperatures according to outdoor
temperatures in primary/secondary piping systems.
The controller also provides pump exercising for 10
seconds every three days and a 20-second post-purge
when the heat demand ceases.
For maximum design flexibility, the MixiMizer
TM
can be
integrated into a thermostat or zoning control system
through the user-selectable "external call for heat/
demand input".
A fully serviceable check valve integrated into the
pump housing eliminates ghost flows in primary/
secondary injection systems and zone applications.
LEDs located on the terminal box are designed to
indicate performance and diagnose faults without
tools.
Other standard user-selectable features include boiler
protection, system/slab "overtemperature" control and
a 5 °F parallel shift of the heating curve.
