If the humidity compensation is activated, the mist units are turned off
when the humidity reaches a user-defined maximum humidity level.
The following diagram sums up the operation of the mist units.

The operation of the mist stage is illustrated in the diagram at the beginning
of this section. The mist stage operates according to a separate timer. Time
on is the running time of the mist units and time off is the off time of the mist
units. If a mist stage is not needed, time off should be set to zero.

Interaction Between Temperature and Minimum Speed
Curves
•
The minimum speed curve can be activated only if the temperature
curve is already activated
•
All points of the minimum speed curve other than the first one are
automatically given day numbers identical to those specified for the tem-
perature curve. Only the first point of the minimum speed curve has an
adjustable day number. This day number must be greater or equal to the
day number specified for the first point of the temperature curve and less
than the day number specified for the second point of the temperature curve
(see example 1).

•
When the minimum speed curve is activated, it will effectively be oper-
ating (i.e. the controller will begin to adjust the minimum speed according to
the specified points of the curve) only when the current day number of the
temperature curve reaches the first day number of the minimum speed curve.
