• When using the function to control the number of units (however excluding the connection to group controller), arrange
the wiring to unit no.1 (master unit). This function becomes enabled in all the units when inputting the signal to unit
no.1 (setting value is also common with the setting value of unit no.1), Signal input to chiller units with address settings
between unit no.2 and 8 are invalid.
• In case of connection to a group controller, the valid enabling and setting value orders are those sent from the group
controller. Signal input to the main unit of the chiller unit and its setting values are invalid.
