FRIEVER Refrigeration Parts Digital Thermostat STC-1000

Operation instruction:

Under controller normal working status, press and hold “ ” key for 3s can turn off the controller; Under controller “off”

status, press and hold “ ” key for 3s can turn on the controller.

Under the controller normal working status, screen displays the current temperature value; also the controller can also

switch the working mode between heating and cooling.

Controller starts refrigerating with cool indicator light on when the measuring temperature ≥ temperature set value +

difference value, and the refrigerating relay is connected; The “Cool” indicator light flashes, it indicates the refrigerating

equipment is under compressor delay protect status; when the measuring temperature ≤ temperature set value, the Cool

indicator light on, and refrigerating relay disconnects.

System starts heating when the measuring temperature value ≤ the temperature set value-difference value, and the “Heat”

indicator light on, and the heat relay connects; When the measuring temperature ≥ temperature set value, the “Heat” indicator

light is off, and the heat relay disconnects
