Drain Pump Control

Purpose
Discharge the condensate stagnating in the indoor unit's drainage plate to prevent the condensate from overflowing
indoor units.
Concept
If the amount of condensate stagnating in the drainage plate reaches a certain level where it may overflow, the Float soft-
ware detects this and activates the drain pump to discharge the condensate to the outside via the hose.
