Misting

The last cooling stage can be used as a mist
stage. Set internal switch #9 to ON to acti-
vate this stage. The number of heating stages
determines which stage is used for misting:

The mist stage cannot be used if two
heating stages are used.
• Mist units start running according to a
timer cycle (On Time and Off Time) when
their start temperature is reached (Set Point
+ Mist Offset + Differential).
• If the humidity compensation is activated,
mist units automatically stop when the hu-
midity level is too high.
