Many units, installed at different locations, can be started
and controlled with a single 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
00m. A maximum of 0 units can be controlled with a sin-
gle 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.
All units can be turned on or off simultaneously using
a remote ON-OFF switch. Also, each unit can be con-
Relay box
trolled individually by each remote controller. Dunning
remote ON-OFF control, a message of "CENTRALLY
CONTROLLED" is displayed on the LCD of the remote
Unit
controller.
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
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 vis-
ible 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.
Remote controller is also available.
With this function, when the power is restored after power
failure, the unit will restart automatically. (However, when
the remote controller POWER ON/OFF button is OFF, the
unit will not start.)
