1、1‑way temperature controller can be set as cooling or heating, use 10K NTC thermistor to control temperature, and control 1‑way relay output. 2、The controlled temperature range is ‑45℃~110℃, widely used in various refrigeration and heating situations. 3、In the cooling mode, when the temperature is higher than (temperature control value plus return difference), the output is turned on, and the output is stopped when the temperature reaches the temperature control value. 4、In heating mode, the output is turned on when the temperature is lower than (temperature control value minus return difference), and the output is stopped when the temperature reaches the temperature control value. 5、Adjustable temperature control value and return difference, with measurement temperature deviation correction function. 6、Adopt DIN rail type installation and advanced isolated power supply design to ensure convenient installation and stable operation of the controller. 7、1‑way 10K NTC temperature sensor input and 1‑way NO and NC output, with delay protection and power‑down memory protection function.
