HYJE-D02H

5. Input / Output Function

The central station has two input functions and two output functions as shown below.
1. Simultaneous Operation / Stoppage
This function is for operating / stopping all the indoor units of the group, which is set by the central station, by the
external contact signal.
2. Simultaneous Operation
This function is for operating all the indoor units of the group, which is set by the central station, by the external
pulse signal.
3. Simultaneous Stoppage
This function is for stopping all the indoor units of the group, which is set by the central station, by the external
pulse signal.
4. Emergency Stop Signal Connection Function
This function is for stopping all the air conditioners connected with the central station by the external emergency
stop signal.
*When other central controller is used together with, even in the state of emergency stop, the RUN / STOP
operation by other central controllers is available.

5. Demand Control Function

The peak-cut according to the electricity is available by the control of air conditioners with the control signal from
the demand control. The group set by the central station is operated by the demand signal as follows.
Demand 1
Demand 2
Demand 3
*1: The control is performed every 15 seconds for the zone, which is subject to demand control, in
descending order of the zone No..
*2: The control is performed every 15 seconds for the zone, which is subject to demand control, in
ascending order of the zone No..
*3: During automatic cooling / heating operation, the activation of "Demand 1" is executed.
*4: For the group with the optional setting of fi xing operation mode, the activation of "Demand 1" is
executed.
*5: For the group with the optional setting of fi xing operation mode or fi xing set temperature, the
activation of "Demand 1" is executed.

6. Simultaneous Operation Output

This function is for outputting signal outward in the case where there is any air conditioner in operation in the
group set by the central station.

7. Simultaneous Alarm Output

This function is for outputting signal outward in the case where there is any air conditioner in abnormal condition
in the group set by the central station.
The input function is set by DSW2 as shown in the table below.
