Take Full Control of Your Temperature — Without Constant Adjustments
Whether you're protecting plants from cold nights, maintaining stable heat for reptiles, or managing precise brewing temperatures, this Digital Temperature Controller makes it easy to keep conditions exactly where you want them. Designed for high-power heating systems and demanding environments, it delivers reliable temperature control with simple plug-and-play convenience.
Precision Temperature Control Made Simple
This 16A Digital Temperature Controller is built to automate heating and cooling devices with accurate temperature management across a wide operating range. With support for up to 1800W heating capacity, it’s ideal for greenhouses, incubators, reptile enclosures, home brewing setups, well houses, and more.
The bright VA display stays easy to read even in low-light conditions, while built-in memory automatically restores your settings after power interruptions — so your setup stays consistent without needing constant resets.
Why This One Stands Out
- Handles high-power heaters with confidence — Supports up to 16A/1800W for stable operation under demanding conditions.
- Wide temperature range for versatile use — Control temperatures from -40°F to 210°F with fine 0.1°F adjustments.
- Easy-to-read VA display — Self-illuminating screen remains visible in dark rooms, grow tents, reptile spaces, and utility areas.
- Heating and cooling modes built in — Automatically switches based on your temperature settings.
- Power memory function — Restores previous settings after outages or unplugging.
- Advanced timer functions — Includes cyclic timing, countdown ON/OFF, and scheduled control modes for flexible automation.

Smart Features That Make Daily Use Easier

With multiple timing modes available, you can automate equipment cycles based on your exact needs — ideal for controlled growing environments, brewing schedules, or maintaining consistent enclosure conditions.
