The Future of Heating Control: Sunster's New Wi-Fi Controller

Smart living has entered a new era—and Sunster is leading the way. If you’ve ever wished you could control your diesel heater from anywhere, the wait is over. Sunster has just released a brand-new controller with Wi-Fi functionality, now available for pre-order.

I had the chance to test it before launch, and I can confirm: this little device packs a serious punch. Let me walk you through the standout features and why this controller is worth every penny.

• Control from Anywhere

With the Sunster app, you can manage your heater no matter where you are in the country—as long as the controller is connected to Wi-Fi. What’s more, you can log in from two phones simultaneously, allowing multiple users to monitor and adjust the heater’s settings remotely.

• Smarter Start/Stop Function

Forget the old limitations. Once your heater reaches the set temperature, it automatically shuts down, then restarts when the temperature drops. Unlike older controllers that only allowed a 2°C shift, this model lets you customize the restart range up to 10°C. More flexibility, more comfort.

• Fine-Tuned Temperature Calibration

With a calibration range of -15°C to +15°C, you can “trick” the thermometer for special needs—for example, keeping the ambient temperature just above freezing to prevent pipes from bursting or equipment from icing up.

• The HoT Function (Heat Overdrive)

Need a rapid boost? The HoT function raises the temperature higher than standard settings—up to 240°C compared to the usual 208–220°C. This is perfect for quickly warming up cold spaces or even burning off soot for cleaner performance.

• Customizable Display

No more glowing screens disturbing your sleep. The controller’s display can be fully turned off during operation or dimmed to your preferred brightness level.

• Ventilation Mode

Sometimes, you just want air circulation without heating. With Ventilation mode, that’s now possible.

• Intelligent Remote Control & Safety

Here’s where it gets even more impressive. The remote control doubles as a carbon monoxide detector. If smoke or dangerous gases are detected, the system automatically initiates an emergency shut-off.

That same remote also works as a wireless thermostat. For example, if you’re heating a tent, you don’t need to run cables—simply place the remote in the space, and it will regulate the temperature via Bluetooth communication with the main controller.

• Built-In Error Notifications

In the event of a malfunction, the app instantly notifies you with an error code and description. No more guesswork, no more digging through manuals.

• Always Have the Manual On Hand

The app comes with a direct link to the user manual, so you’re never stuck searching online when you need instructions fast.

• Future-Proof with Updates

Perhaps the most exciting part: the controller is update-ready. That means Sunster can add new functions and enhancements over time, making your investment future-proof.

Final Thoughts

The new Sunster Wi-Fi controller isn’t just a gadget—it’s a leap forward in how we manage heating systems. From remote control convenience to safety features and upgradeability, it redefines comfort, efficiency, and peace of mind.
