Selection of Evaporator(Air Handling Unit)
See table below for applicable units
Selecting the capacity setting 'Option PCB'(Accessory) according to the capacity mentioned
below.
- The corresponding capacity setting 'Option PCB' needs to be selected depending on the
need capacity.
- After checking the need capacity, remove the 192 k Option PCB equipped in the main
PCB, and set up the Option PCB fitted the need capacity in the main PCB.
