W3103 Digital Temperature Controller – 220V, 30A, -19~99℃, 5000W, with Sensor | Home & Industrial Use

Tired of temperature fluctuations ruining your incubator, aquarium, or heating setup? The W3103 Digital Temperature Controller gives you precise, automated control over any heating or cooling device — right from a compact, easy-to-wire unit built for Indian homes and workshops.

The W3103 operates on AC 230V and handles up to 5000W / 30A, meaning it can comfortably drive heavy-duty heaters, solenoids, and industrial elements that ordinary thermostats simply cannot manage. Its NTC sensor delivers ±0.2°C accuracy across a wide -19°C to 99°C range, and a built-in calibration offset (±10°C) lets you fine-tune readings to match your exact environment. The 2-metre sensor wire gives you enough reach to mount the controller safely away from heat sources.

What sets the W3103 apart is its three intelligent timer modes: F1 Intermittent Mode cycles the device on and off at custom minute intervals (great for fermentation or mushroom cultivation), F2 Scheduled Shutdown automatically powers off after a set duration, and F3 Scheduled Start turns your device on at a programmed time — all without a separate timer relay. This makes it ideal for egg incubators, fish tanks, seedling heat mats, homebrew fermenters, reptile enclosures, DIY electronics, and small industrial heating rigs.
