STC-1000 110-220V LCD Digital Temperature Controller Thermostat with Sensor Features Switch mode between cooling and heating Check the temperature by setting the temperature setpoint and the difference Temperature calibration Cooling control output delay protection Alarm if temperature exceeds temperature limit or sensor error Menu description Code - Function - Setting range - Standard F1 - Temperature setpoint - 50 to +99.9C - 10C F2 - Difference setpoint - 0.3 ~ 10.0 C - 0.5 C F3 - Compressor delay time - 1 ~ 10 minutes - 3 minutes F4 - Temperature calibration value - 10 C to +10 C - 0 C Operating instructions 1. Parameters can be checked. In normal operation, press the "up" key to display the temperature setpoint. Press the "down" key to display the difference. 2. 2. Parameters can be set. In normal operation, press and hold the "s" key for more than 3 seconds to enter the parameter change mode, the "Set" indicator lights up and the screen displays the first menu code "F1". Press the "up" key or "down" key to move up and down and display the menu items and menu item codes. Press the "s" key to display the parameter value of the current menu. Pressing the "s" key and holding down the "up" or "down" key at the same time immediately selects and sets the parameter value for the current menu value. When the setting is complete, press and immediately release the "(I)" key to save the changed parameter value and return to the normal temperature display. If no key is pressed within 10 seconds, the system does not save the changed parameters and the screen returns to the normal temperature display. 3. Restoring system data If the system is powered up, it will check itself and the screen will display "Er" when the fault is cleared. At this point, press any key to restore the default values and enter the normal operating mode. It is recommended to reset the parameter values in this case. Operation manual In normal operation, press and hold the "(I)" key for 3 seconds to switch off the controller. In the controller status "Off", press and hold the "(I)" key for 1s to switch the controller on. In the normal operating state of the controller, the current measured temperature value is displayed on the screen; in addition, the controller can switch between heating and cooling modes of operation. If the measured temperature > = temperature setpoint + difference and the cooling relay is connected, the controller starts cooling with the cooling display on; when the "Cool" indicator flashes, the cooling system is in compressor delay protection; the temperature setpoint, the cooling display and the cooling relay are disconnected when the temperature is measured. When the measured temperature value = temperature setpoint, the "Heating" control lamp is off and the heating relay is disconnected. Error/alarm description Sensor fault alarm: When the sensor is open or short-circuited, the controller activates the sensor fault alarm mode, the entire operating state is switched off, the buzzer is alarmed and the display shows "EE". Press any key to cancel the alarm tone, after the fault the system returns to normal temperature display and the fault is cleared. When the temperature measurement exceeds the temperature measurement range, the controller activates the error alarm function, the whole operation state ends, the buzzer alarm is activated and the display shows "HH". Press any key to cancel the alarm, when the temperature returns to the normal measurement range, the system returns to the normal working mode display. Safety regulations - Caution. 1. Strictly distinguish between sensor leads, power supply lines and output relay connections to prevent incorrect connections or relay overloads. 2. Hazard: It is forbidden to connect the wire clamps without switching off the power supply. - Warning. Do not use the machine in environments with excessive humidity, high temperatures, strong electromagnetic interference or strong corrosion. Packing list. 1 * Thermostat temperature controller switch
