Specification: Condition: 100% Item type: Temperature Controller Material: ABS flame retardant plastic case Color: As picture shown Weight: Approx. 130g Power supply voltage: 110-220VAC ± 10%, 50/60Hz (or DC12V / DC24V) Measuring and controlling temperature range: -50℃～+110℃ Resolution: 0.1°C Accuracy: ±1℃ Accuracy: ±1℃ Relay output capacity: Heating: 10A/240VAC, Cooling: 10A/240VCA Sensor h type: imported NTC sensor, cable length 1m/3.3ft Description: P0. Cooling and heating mode Please set to C for high temperature start as cooling mode Low temperature start is heating mode, please set to H P1. Hysteresis setting In heating mode (H): the measured value ≤ the set value-when the hysteresis starts to output the heating to the set value and stops. In the cooling mode (C): when the measured value ≥ the set value + hysteresis, the output cooling is started and the set value stops. P2. The highest setting range: the highest value does not exceed this value when setting the temperature P3. The lowest setting range: the lowest value when setting the temperature is not lower Package List 1 x Temperature Controller 1 x Instruction
