Explanation for SYSTEMS

This unit can be made a part of two different systems: as

part of an interlocking system together with VRV or SkyAir

system and as the independent system using only the ERV

unit. The remote controller is required when using the unit

as the independent system.

Ask your dealer what kind of system is set up before oper-

ation.

See the operation manuals for details on how to operate

each remote controller.

OPERATION for EACH SYSTEM (Refer to figure 2)

• Independent system

The ERV unit can be operated by the remote controller.

• Interlocking system with VRV or SkyAir system

Both of the air conditioner and the ERV unit can be operated by

the remote controller.

In mild climates when only the ERV unit is used without the air

conditioner, select "ventilation mode" with the operation mode

selector button.

• Centralized system

When the remote controller is not connected with the ERV unit,

the centralized controller controls it.

When the remote controller is connected with the ERV unit,

operation can be done by the centralized controller or the

remote controller.

During the indication of centralized control "

the display, the ON/OFF and timer operation may not be possi-

ble with the remote controller.

Other operations can be performed using the remote controller.
