Digital thermostat STC-1000, range -50~99°C, 12V power supply

Product detailed description

STC-1000 is a digital thermostat that regulates temperature based on data from an external sensor. It has two independent circuits with relay outputs, so one output can control heating and the other cooling. This version is powered by 12 V DC.

You can set the temperature in the range –50 °C ~ 99.9 °C with a resolution of 0.1 °C (the model name indicates the range -50~99°C). It is not a standalone device, so its installation should be entrusted to a professional.
