Control details

3-1. Drain pump control

•Always drain pump ON during the COOL and DRY mode operation. (Regardless of the thermostat ON/ OFF)

•When the operation mode is changed from COOL or DRY to any other mode (including Stop), the drain pump continues to run for 3 minutes.

Drain sensor function

• The indoor circuit board energizes the drain sensor at a fixed voltage for a fixed

duration. After energizing, the circuit board then compares the drain sensor’s

temperature to the one before energizing, and judges whether the sensor is in

the air or in the water.

Basic control system

•While drain pump is turned on, it will repeat the following control system and judge whether the sensor is in the air or in the water.

•Drain sensor temperature rise (Δt)

•Temperature of drain sensor before current is applied (T0) •Temperature of drain sensor after current is applied (T1)

[ Δt = T1 – T0 ]

(1)Initial setting : Start at COOL mode and horizontal vane.

(2)Vane position : Horizontal →Downward A →Downward B →Downward C→Swing

→

(3)Restriction of the downward vane setting

When setting the downward vane A, B or C in [Medium1], [Medium2] or [Low] of the fan speed notch, the vane changes to horizontal position after 1 hour has passed.
