Note:

Returning water temperature control is set as default and recommended

The above data is obtained in the laboratory. In actual use, it will be biased by the influence factors, such as
installation location, etc.

* Saline-water Mode (for ethylene glycol aqueous solution only), and the set value shall be selected in
accordance with ethylene glycol’s concentration

Water temperature’s operating range diagram for standard unit is as follows
Note: The above diagram is standard unit operating range diagram. For the operation range of saline-water mode,
please consult Johnson Controls
