Digital thermostat STC-1000, range -50~99°C, 24VDC power supply

Product detailed description

The thermostat STC-1000 in the 24 V DC version belongs to digital controllers that operate with an external temperature probe. It contains two independent circuits with relay outputs: one can be used to switch on heating, the other for cooling.

You can set the temperature within the range of –50 °C to 99.9 °C with a resolution of 0.1 °C (in the model name the range is –50~99°C). The device does not operate independently, so please have it installed by a qualified technician.
