Notice:
1) For installation of multi-module, the most modules should be not more than 8 modular units.
2) For installation of multi-module, please drill a dead hole(
Φ
9mm) at the total water outlet pipeline,
and move the total water effluent temp. sensor at No.0 address to the hole.
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 temp. sensing bulb, water flow switch and auxiliary electric heater are under control of the
main module.
● One wired controller and one water flow switch 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.
3.6 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.
The maximum chilled water flow is limited by the permitted pressure drop in the evaporator. It is provided in
the below table.
If the system flow is more than the maximum unit flow rate, bypass the evaporator as shown in the diagram to
obtain a lower evaporator flow rate.
