6.6. Stir Fans
The controller has one stir fan output that
can either operate during minimum ventilation
cycles or when the room temperature falls
below a user-defined limit.
• Based on the room temperature:
When they are based on the room tempera-
ture, stir fans start running in timer mode
when the room temperature falls below
their Start Temperature; they return to a
stop when the room temperature increases
and reaches the output’s stop temperature.
These Start & Stop Temperatures are related
to the house set point which means they are
automatically adjusted when changes occur
to the set point.

good air circulation when the fans are not
running.
