Patrol operation start condition• When the unit operation is started with “OFF/ON” button.• When the unit stops, “Patrol” button is pressed, Patrol individual operation will start.• During cooling only operation, “Patrol” button is pressed.b.

Control Contenta. Patrol Sensor Control• First 2 minutes from Patrol function activates is stabilization time, during stabilization time, no air dirtiness level is monitored.The Air Dirtiness level is set to level 2.• After that, gas sensor starts to record the resistance value at fixed interval. Higher resistance value indicates cleaner air.• The air dirtiness level is monitored by comparing the current resistance value with maximum resistance value from time to timeto get the Air Dirtiness Value.• There are 3 air dirtiness levels, based on the Air Dirtiness Value:- Air Dirtiness level 0: Clean- Air Dirtiness level 1: Moderate- Air Dirtiness level 2: Contaminated
