For analog input, switches between
input voltage and input resistance.

N/C
Switches the local remote control temperature setting operation between push priority and
operation prohibited.
Switches the room temperature monitor output between the temperature used by the
controller (when heating, the intake temperature with shift, or the remote control sensor)
and the intake temperature.
Cut (fixed voltage) JP4, although no change the setting temperature with Seri-Para I/O
Unit. Do not input voltage to No.3 and 4 (AI ) of CN1 at the time.
When using the Seri-Para I/O Unit, it is standardized to connect a remote controller or a
centralized control system (i.e. System controller). To use the Seri-Para I/O Unit by itself
(without a remote controller or a centralized control system), cut JP5. In this regard,
however, the operational functions (such as operation mode, fan speed and wind direction)
will be limited with only the Seri-Para I/O Unit.

The indoor temperature monitor output is
from 4 to 20 mA DC (5 to 36°C), and the
temperature can be set in steps of 0.5°C.
Take care of the measurement units used by
the central monitor. The wiring specifications
are for analog input.
Keep the load resistance below 240
