Features 1Control Output: Single way thermostat you can set the cooling or heating control temperature using 10K universal NTC thermistor temperature measurement control a relay normally open or normally closed output. 2Cooling Mode: When the thermostat is in cooling mode the output is turned on when the temperature is higher than the temperature control value plus hysteresis and the output is stopped when the temperature control value is reached; 3Heating Mode: When the thermostat is in heating mode the output is turned on when the temperature is lower than the temperature control value minus hysteresis and the output is stopped when the temperature reaches the temperature control value. 4Deviation Correction: The temperature control value and the return difference value are regulable and the temperature measurement deviation correction function is available. The control temperature range can get 45 to 110 which is widely used in various refrigeration and heating control places. 5Easy Installation: Adopt DIN rail mounting method featuring easy and quick installation just follow the normal process to install successfully friendly to novices. 6Isolated Power Supply Design: Adopting advanced isolated power supply design it can ensure stable reliable and continuous operation of the controller when the power supply changes between 110240V. Specification Item Type: TemperatureControllerModel: SN093Material: PCInstallation: Standard din rail mounting or fixed installationDisplay: 22 x 11mm 3 bit LED displayPower Supply: 100-240VACPower: 2WKey: Press the membrane keyboardInput: Single thermistor temperature sensor output (10K) NTC measuring range from -50 degrees Celsius to 120 degrees CelsiusOutput:1. Single way relay non contact for cooling output NC contact for output heating.2. Current output contact capacity is 5a for limited load and 1a for inductive load. it can control 1000w electric heating or 200w motor or pump. AC contactor is needed to extend the capacity to accommodate higher loads.Operating Temperature: -10-50Measuring Range: -50-120Setting Range: lower limit: -45 control temperature control upper limit control temperature -110Control Range: -45 - 110Temperature Control Return Difference: 1 - 30 Delay Time: 0 - 300 secondsDeviation Correction: -25 - 25 Package List 1 x Thermostat1 x Manual Note Pay attention to follow the correct operation
