The length of a wire that connects a Serial/Parallel I/O unit and the
equipment should be less than 50 m for analog signal, and less than
100 m for digital signal.
*1 About Emergency Stop Signal
This signal immediately stops all indoor units connected to the
Serial/Parallel I/O unit and disables any manual operations through the
remote controller. When this signal is off, manual operations through
remote controllers become enabled.
*2 About Temperature Setting Input (analog input)
When the setting signal for room temperature is within DC1 - 5 V, the
setting value is sent to the applicable group, and each air conditioner in
the group sets a setting temperature within a predetermined range for
the air conditioner. Temperature is indicated in 1°C intervals. Check the
precision (resolution) of the central monitor. When a signal more than
1.0 V is inputted, temperature setting can not be carried out with the
remote controller that shows the sign, "Under Centralized Control". With
a signal less than 1.0 V, temperature setting can be made with the
remote controller.

*3 About the Room Temperature Monitor (analog output)
The current of the room temperature monitor signal is within DC4 - 20
mA (5 - 35 ). And temperature is indicated in 0.5
precision (resolution) of the central monitor.

5. Zone Address Setting Switch of Serial-Parallel I/O
When controlling the Serial/Parallel I/O units in two or more zones, set the
zone address for each unit (setting switches No. 1 and 2 on SW1).
To control a Serial/Parallel I/O unit in only one zone, adjust the setting of
the unit for Zone 1.
To control Serial/Parallel I/O units in two or more zones, adjust the setting
of one of the Serial/Parallel I/O units for Zone 1.

6. Setting Procedure for Central Control Address
Turn on the main powers of all air conditioners.
After completing test run of the air conditioners, set central control
addresses as follows.
(Central control addresses will be automatically set in increasing order of Unit No.)

Carry out each input after the display return to the normal mode, and
check the operating status of each air conditioner. The number shown on
the setting display is the central control address and the Unit No. of the air
conditioner.
