9-4. Drain Pump control
CCU intervenes in drain pump control of the indoor unit according to the setting in EEPROM in the outdoor unit.
The drain pump operates from CCU control at the following condition.
- DP counter 5
* The DP counter counts each oil recovery control.
- Liquid temperature (E1) in the indoor unit which selected cooling mode < 0 °C
* Regardless of operating / stopped.
- Low Silhouette Ducted type indoor unit
In Low Silhouette Ducted types, dirt might be accumulated when water collects in the drain pan for a long
term. Therefore, the drain pump works longer to drain water surely.
* To activate this function, it is necessary to set it to EEPROM on the main outdoor PCB.
