to bring from the outdoor unit.

- Making up the network system easily.

- Saving the total wiring length.

- Preventing incorrect connection.

- Saving installation time.
ADOPTION TO LARGE SCALE BUILDINGS

1 VRF network system allows to form large scale application as follows: ●

- Total transmission wiring length can be extended up to 3,600 m with signal amplier unit.

- Indoor units can be connected up to 400.
