  1. Key Description
    Project Function Description Operating Procedures
    Basic Settings Access to basic settings Press “Set” for 3 seconds to display “ST1”, press “â–²” to cycle through the panel: “ST1” “ST2” “ST3” “Ec”.
    St1

    （First Circuit Set Point）

    		 Start when temperature rises and temperature ≥ ST1 value

    the state switching starts (i.e.: normally open →normally closed, normally closed → normally open or DC24V ®→DC0V)

    		 When “ST1” is displayed, press the “Enter” key to enter the setting state of the first loop setting value, the blinking bit is modifiable at this time, press the “â–²” key, the blinking bit can be modified from 0 to 9 in a cycle, press the：”â–¶” key, the blinking bit can be moved in a cycle from thousands to single digits.  Press the “â–²” and “â–¶ ” keys to complete the setting of the set value, press the “Enter” key to store the set value and jump to display “ON ” or “OFF”.
    ON/OFF (First Circuit Start State) When “ON” is displayed, the circuit is switched on

    When the temperature rises and the temperature < ST1 value, the output

    is normally closed or DC24V;

    When “OFF” is displayed, the circuit is normally closed or DC24V when the temperature rises and the temperature is <ST1.

     

    		 Press the “â–²” key to switch back and forth between “ON” and “OFF”; press the “Enter” key to store the status value and jump to display “OL”.
    OL (First Circuit Delay Value) Temperature drops and temperature ≤ (ST1-OL)

    value, the output state is reset.

    		 When “OL” is displayed, press the “Enter” key to enter the setting state of the first circuit set value, the blinking bit is modifiable at this time, Press the “â–²” key, the blinking digit can be cyclically modified from 0 to 9, press the “â–¶ ” key, the blinking digit can be cyclically moved from thousands to individual digits. Press the “â–²” and “â–¶ ” keys to complete the setting of the set value, press the “Enter” key to store the delay value and jump to the display of “ST1. “
    The St2 Circuit Is Set As Above For The St1 Circuit And Will Not Be Described Further.
    Exit Exit basic settings When “Ec” is displayed, press the “Enter” key to exit the basic settings.
  2. Set Flow ChartSmart Temperature Switch1Note: Depending on the model and the number of output circuits, some circuit settings are not valid.

    â‘ Setting value: Pressure value at which the switch operates.

    â‘¡Start output state: oN for display pressure below set value switch action; oFF for display pressure above set value switch action.

    â‘¢Delay value: delay value = set value – reset value, i.e. switching difference.

  3. Fine Adjustment Of Current ValuesSmart Temperature Switch2Press and hold the “ENTER” and “â–²” keys simultaneously for 5 seconds, the DA value corresponding to 4mA will be displayed roughly, press the “â–¶” key to adjust down, “â–²” key to adjust up, press the “ENTER” key to enter 20mA fine adjustment, press the “▶ ” key to adjust down, “â–²” key to adjust up. After adjustment，Press “ENTER” key to exit, that is to complete the current fine-tuning. (Note: The factory has been adjusted, no need to fine-tune under normal conditions.)
