Please pay attention to the following items when installing multiple modules:
● Each module corresponds to an address code which can’t 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.
12.2.9 Chilled water flow
Minimum chilled water flow
The minimum chilled water flow is shown in the below table.
If the system flow is less than the minimum unit flow rate, the evaporator flow can be recalculated, as shown
in the diagram.
