A laser tuber customer purchased S&A chiller CW-5000, however, he found the temperature on the chiller stays between 27-30C, too warm, he try to restored it to factory settings and nothing has changed with the temperature. As the chiller temperature control is intelligent mode as factory setting which will self-adjust controlling parameters according to ambient temperature for meeting equipment cooling requirements. If you need to adjust the water temp. you need to change intelligent mode to constant mode.
