Description: The one-way temperature controller can set as "refrigerating" or "heating", using 10K general NTC thermistor to control temperature, control the one-way relay (NO, NC) output. The temperature range controlled is -45 Celsius ~110 Celsius. Under refrigerating mode, the output opens when the temperature is above (temperature control value + return difference) and stops when temperature is at the temperature control value.Under heating mode, the output opens when the temperature is below (temperature control value - return difference) and stops when temperature is at the temperature control value. Adjustable temperature control value and return difference value with correction function for measured temperature deviation.Adopt DIN guide rail type installation, easy and fast to install.Adopt the advanced design of isolating power supply, ensuring the controller work steadily, reliably and continuously when the power supply changes between 100V~250V ADC. The temperature sensing line could be connected with general wire for 100 meters.Set the parameter to conserve long-term memory of power-down.
