ETC‑902 Digital Temperature Controller (12‑24V DC) – Low‑Voltage Precision

Control heating or cooling devices with low‑voltage DC power using the ETC‑902 Digital Temperature Controller. Designed for 12V or 24V systems – perfect for RVs, boats, solar‑powered greenhouses, off‑grid incubators, automotive applications, and battery‑operated equipment.

The clear dual‑display shows both current temperature and your target setpoint simultaneously. Adjust the set range with simple push‑buttons; the built‑in relay automatically switches connected devices on or off when the temperature moves outside your desired limits. An accurate sensor probe is included for instant installation.

Adjustable differential (hysteresis) prevents frequent cycling, protecting your compressor, fan, or heater while saving energy. The compact panel‑mount design fits standard cutouts, making retrofitting quick and easy.

Stop worrying about temperature swings. The ETC‑902 (12‑24V) delivers reliable, automatic regulation wherever low‑voltage power is available – from camper freezers to DIY fermentation chambers.

Set it. Forget it. Control on the go.
