Please pay attention to the following items when installing multiple modules:
- Each module corresponds to an address code which cannot be repeated.
- Main water outlet temperature sensing bulb, target flow controller and auxiliary electric heater are under control of
the main module.
- One wired controller and one target flow controller are required and connected on the main module.
- The unit can be started up through the wired controller only after all addresses are set and the aforementioned
items are determined. The wired controller is ≤500m away from the outdoor unit.
