PV input 1
Remote auciliary analog
input (if equipped)
Contact inputs
* After the control output terminal is specified by the parameter OT,
other current output terminals can be used as retransmission output.
Sensor burnout occurs when PV or RSP input burnout occurs.
However, burnout is not detected if input is not conncted.
