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 than this value P4 Package List 1 x Temperature Controller 1 x Instruction
