Technical Parameters:Temperature control range: -50~120°CResolution: -9.9~99.9 when 0.1 °C Other temperature range 1 °CTemperature measurement accuracy: 0.1 °CControl accuracy: 0.1 °CHysteresis accuracy: 0.1 °CRefresh rate: 0.5 SInput power: DC 12VMeasurement input: NTC (10K 0.5%) waterproof sensorOutput: 1 relay output, capacity = 20AEnvironmental requirements: -10~60°C Humidity 20%-85%Specification size: 79mm*43mm*26mmInstructionsConnect the power supply and equipment to supply power to the controller. At this time, it is displayed as measuring temperature. Press SET once, the display temperature will flash, press +- to set the desired temperature (press +- to quickly raise and lower) After finishing, press SET to confirm the return. At this time, the controller automatically performs relay on/off according to the setting! The output of the thermostat is a 20A relay, which satisfies various high-power loads. When the control circuit is connected, the thermostat can be powered. At this time, the display shows the ambient temperature.Indicator, digital tube and buzzer status descriptionIndicator light: Blinking indicates cooling or heating start delay, always on indicates that the relay is closedDigital tube: Display LL is the sensor open circuit, please follow the instructions to connect the sensor; display HH is out of the measurement range, the thermostat will force the relay to be disconnected; display --- for high temperature alarmPackage includes: 1* thermostat, 1* manual
