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 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.

Chiller water flow
Minimum chilled water flow: if the system flow is less than the minimum unit flow rate, the evaporator flow can be
recirculated, as shown in the diagram below.
