(2) Explanation of control mode switches (SW5, SW6, and SW9)
Use these DIP switches to configure the local control mode setting. Though the control mode
setting is configured at the factory, check the setting to ensure that it is compatible with local
conditions. Use SW5, SW6 and SW9 on the CPU control board to change the control mode.
Before changing it, turn off the power of the control circuit/pump breaker (CB1) inside the power
control box and check that the power of the CPU board is shut off. After configuring the setting of
each switch, turn the power back on.
(Note 1) Do not change the factory defaults.
However, SW6-7 need to be changed after water filling at the site.
