- When the room temperature falls below the
start temperature of stage 2, stage 2 fans run
intermittently according to the same timer as
the one used by stage 1.
- When the room temperature increases
above the start temperature of stage 2, stage
2 fans start increasing in speed continuously.
Low Temperature Override: If the room tem-
perature gets too cold while the controller
is in minimum ventilation, low temperature
override functions can be enabled to reduce
the speed of stage 1 fans and to stop stage 2.
This allows reheating the room faster. Refer
to the "User Setup Menu" on page 11
to enable the Low Temperature Override
functions.
