Adopt the water-level switch to control the action of drain pump.
Main action under different condition :( every 5 seconds the system will check the water level one time)
1. When the A/C operates with cooling (including auto cooling), dehumidifying, and forced cooling mode, the
pump will start running immediately and continuously, till stop cooling.
2. Once the water level increase and up to the control point, LED will alarm and the drain pump open and
continue checking the water level. If the water level fall down and LED disalarmed (drain pump delay close 1
minute) and operate with the last mode. Otherwise the entire system stop operating ( including the pump)
and LED remain alarming after 3 minutes,
