Digital Temperature Controller with Dual Mode Heating/Cooling, 10A 110V 220V

STC-1000 Digital Temperature Controller - Product Description Overview and key benefits - Dual-mode control for cooling and heating, allowing flexible use in temperature regulation applications. - Precise setpoint control with adjustable differential (hysteresis) and temperature calibration for reliable results. - Built-in protections including compressor delay on cooling output and audible alarm on temperature limit exceed or sensor fault. - Compact panel-mount design and multiple power supply options for easy integration into existing systems. - Includes a 1 meter NTC sensor for immediate installation and operation. Main functions and user operation - Mode switching: Operates in cooling mode or heating mode selectable via the controller. - Setpoint and differential: Set the desired temperature and the differential value to control switching thresholds. - Temperature calibration: Offset adjustment to correct measurement deviations. - Compressor delay protection: Cooling output includes a delay to protect compressors from rapid cycling. - Alarm: Alarm triggers when measured temperature crosses configured limits or when a sensor error occurs. - Display and indicators: Three-digit LED display with minus sign, status indicator lamps for cooling and heating, and a set indicator lamp to show parameter editing. - Basic key operation: View setpoint and secondary values with the view key. Enter parameter edit mode by holding the set key for 3 seconds. Use up and down keys to change menu items and parameter values. Press the set key to confirm a parameter. Hold set plus an adjustment key together for faster value changes. If no key is pressed for 10 seconds, the system will exit edit mode without saving changes. - Startup and reset: On power-up the controller performs a self-check. If a startup error occurs, the display indicates the error and pressing any key restores default parameters and returns the unit to normal operation. It is recommended to reset parameter values after such a restore.
