All guides · Diesel heating
I would choose the controls based on where you are standing when the heat needs to be turned on. A panel, local app control, and remote starting from home solve different needs.
Start with your daily life on board
Do you want to turn a dial from your bunk, maintain a specific temperature in the evening, or start the heat before you arrive? Write down your desired functions before comparing panels. This way, you avoid buying a display with many menus if your needs are actually simple.
Four ways to control the heat
| Control | What you should investigate |
|---|---|
| Fixed panel | Temperature function, power control, timer, readability, and placement. |
| Bluetooth | Local connection to the phone, app, and compatibility. |
| WiFi | Whether the system uses a local connection or supports remote access via the internet. |
| Modem/mobile network | Supported network, coverage, SIM, subscription, and compatible heater. |
An app on your phone does not automatically mean that the heater can be controlled from home. This must be stated in the specific device's functions and connection requirements.
Mini Control or Comfort Control for AUTOTERM?
The AUTOTERM Mini Control has a dial and a small screen. The manufacturer describes, among other things, temperature, power, and ventilation functions for the Air series. Comfort Control has more operating functions and advanced timers.
I would choose based on desired control and compatibility with the specific heater. For older heaters, the version and connections should be clarified before purchasing. A controller from another brand cannot be assumed to fit, even if the plugs or appearance look similar.
Three needs provide three different shopping lists
- “I want to turn it up from my bunk”: start with a suitable panel and a good location.
- “It must be warm at seven o’clock”: investigate timer function and temperature measurement.
- “I want to turn it on before I leave home”: check for a supported remote access solution and the connection at the boat.
Remote starting requires an installation that is ready for it
Clarify power supply, coverage, and the manufacturer's conditions for remote control. A remote start module will not make an unsuitable location or an unfinished installation ready for operation. The heater's normal shutdown must still be able to be completed according to the manual.
For modem solutions, I would check the exact version and supported mobile networks. A product name alone does not tell you if an older modem version works with the desired operator.
What should you send to me?
Send a photo of the heater's rating plate, current panel, and plugs, as well as the functions you want. Also, let me know if the boat has a fixed internet connection. Then I can help evaluate the panel, cable, and any extra module as a whole.
