E-ICING OF STAGE 2 FANS
A de-icing cycle is provided for de-icing of Stage 2 fans in cold weather
conditions. When the de-icing cycle time has elapsed, the Stage 1 fans
are stopped. The Stage 2 fans are started at full speed for 2 seconds and
then operated at the Stage 2 minimum speed during a user-defined de-
icing time. Then, the Stage 2 fans are turned off and operation of Stage
1 fans is resumed at the appropriate speed. To deactivate de-icing, set
de-icing time to zero.
