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
