E1 – Econofresh outdoor cooling mode / KPI ventilation mode
This function is used to set the ventilation mode of the ventilation unit with energy / heat recovery
KPI: This function is useful to set the heat exchanger ventilation mode. The setting condition and ventilation mode are
shown below:

Setting Ventilation mode Contents
00 Automatic ventilation
Effective ventilation mode selection (ventilation
with total heat exchanger or ventilation bypass)
to save energy by detecting the difference in
temperature between indoors and outdoors.
01 Ventilation with heat exchanger
Heat is exchanged continuously when the heat
exchanger is started.
02 Ventilation bypass (without heat exchanger)
Heat is not continuously exchanged when the
heat exchanger is started.

E2 – Increased air supply volume
This function is useful when the air supply volume is to be increased using the high-speed, one-way valve on the fan motor
during total heat exchanger operations. This increases the pressure in the room with greatest air volume in relation to
adjoining rooms and prevents the entry of contaminated air or unpleasant smells.
