: Energy saving operation is run when all the following conditions are met.
1) One or more ERV units must be connected to MWR-WE10 (without or with indoor unit(s) )
2) Either the indoor unit or ERV must be ON (if the indoor unit is ON, it must not be FAN mode).
3) ERV must not be in Outing mode
4) ERV external control must not be enabled.
5) ERV must not be in “Centralized” control mode.
6) ERV must not be in “Kitchen Hood” control mode.

It is possible that dust can stick the material during airflow and bacteria can breed in drain pan
Don’t need to clean
because Self-Cleaning

Relatively Short
Possibility of corrosion and contamination is higher than Inorganic material
as compared with mineral material
Relatively Long
Because ceramic itself is inorganic
