7.3.1.4 Pump output adjustment function
If an excessive flow rate occurs due to low pressure loss of the circulating loop, adjust the Main water pump output
so that the flow rate is reduced.
Using the Dip switch on the PCB(Terminal), 3-level setting is possible.
Be aware that an excessively low flow rate may cause problems including diminished capacity, poor circulation,
unavailable flow switch control, and freezing of the water heat exchanger.
SW5, SW6: To switch flow rate (3 Levels of speed) of Main water pump in the HP unit.
At the factory shipment, both SW5 and SW6 are OFF, which means Level 3. (If both are ON, it is Level 3.)
