2. MSP Duct Type Functions
2.1 Drain Pump Control
Normal Operation
The float switch is ON in normal operation.
When cooling operation starts (thermostat ON), the drain pump turns ON simultaneously.
After the thermostat turns OFF, the drain pump continues to operate for another 5 minutes.
The aim of residual operation after thermostat OFF is to eliminate the dew that condenses
on the indoor heat exchanger during cooling operation.
If Float Switch is ON with Thermostat ON in Cooling Operation
When the float switch turns OFF, the thermostat turns OFF simultaneously.
After the thermostat turns OFF, the drain pump continues to operate for another 5 minutes.
Notes:
1. If the float switch turns ON again during the residual operation of the drain pump, cooling
operation also turns on again (thermostat ON).
2. If the float switch remains OFF even after the residual operation of the drain pump has
ended, the error code
A3
is displayed on the remote controller.
3. The drain pump turns OFF once residual operation has ended, then turns ON again after 5
seconds.
4. After
A3
is displayed and the unit comes to an abnormal stop, the thermostat will remain OFF
even if the float switch turns ON again.
