Many units, installed at different locations, can be started
and controlled with a aingle remote controller. The remote
controller can be mounted in a different location using a
non-polar two-wire cable, which can be extended up to
500m. A maximum of 50 units can be controlled with a
Unit
single remote controller. All units operate in the same
mode.
Two remote controllers can be used to control either one
unit or a group of units. Units can then be controlled from
a distance or at close range. Units operate according to
the latest command from either remote controller.
Unit
All units can be turned on or off simultaneously using a
remote ON-OFF switch. Also, each unit can be controlled
Relay box
individually by each remote controller. Duning remote
ON-OFF control, a message of "CENTRALLY CON-
TROLLED" is displayed on the LCD of the remote con-
Unit
troller.
This is available for both one unit control and several units
control.
By grouping the remote controllers in one place, several
units installed at different locations can be controlled indi-
vidually, and operation conditions of all units are visible
without a special control board. The control method is the
Unit
same as that of the single unit with a single remote con-
troller.
Several units can be controlled with a remote control dis-
play board. Operation conditions of all the units are visi-
ble with the remote control display board.
Individual control by each remote controller is also possi-
Unit
ble.
A unit can be started or stopped with the circuit breaker
on or off.

With this function, when the power is restored aftar power
failure, the unit will restart automatically. (However, when
the remote controller POWER ON/OFF button is OFF, the
unit will not start.)
