TEMPERATURE CONTROLLER PANEL DESCRIPTION
S&A industrial water chillers are popular for its 2 temperature control modes as constant
temperature and intelligent temperature control.Generally speaking, the defaulted setting for the
temperature controller is intelligent temperature control mode. Under intelligent temperature control
mode, the water temperature will adjust itself according to the ambient temperature. However,
under constant temperature control mode, users can adjust the water temperature manually.
Suggestion:
Intelligent temperature control mode for QBH connector/optics
Constant temperature control mode for laser device

Temperature controller panel description：
Alarm function
(1) Alarm Display:
When alarm occurs, the error code and the temperature will be alternately displayed.
(2) To suspend the alarm:
In alarming state, the alarm sound could be suspended by pressing any button, but the alarm display remains until
the alarm condition is eliminated.
ALARM AND OUTPUT PORTS
In order to guarantee the equipment will not be effected while abnormal situation happens on the chiller,
CWFL-500 series chillers possess alarm protection function.

CHILLER APPLICATION
WAREHOUSE
18,000 square meters brand new industrial refrigeration system research center and production
base. Strictly execute ISO production management system, using mass modularized standard
produces, and standard parts rate up to 80% which are the source of quality stability.
Annual production capacity of 60,000 units, focus on large, medium and small power chiller
production and manufacture.
