CAUTION
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 sensor and auxiliary electric heater are under control of 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.
