Description: Function: -Cooling or heating working -Hysteresis setting （for example, environment temp is 30℃, the setting temp is 25℃, the hysteresis setting temp is 2℃, when cooling reach to 23℃, relay off and cooler off, then temp go up to 25℃, the relay on and cooler start） -Set highest/ lowest upper limit temp to avoid accident -Temperature calibration, you can calibrate temp according to requirement Temp (after) = temp (before) + correction value -Turn on/ off button -Delay start to protect your device -High temp alarm, when measure temp reach to the setting temp, controller will alarm - factory settings, when the setting value is confusion, please factory Specification: Specifications: Control Temp Range: -50-120℃ Power Requirement: DC/AC 12V Resolution: 0.1℃ Measuring Input: NTC(10k 0.5%) waterproof sensor 0.5m Relay Output: 1 way Rated Current: 10A Control Accuracy: 0.1℃ Hysteresis Accuracy: 0.1℃ Refresh Time: 0.5s Power consumption: Static current
