Smart control for your Timberline heating system

Updated 9 October 2026Heaty

The Timberline heating system can be connected to Camper Jarvis with the Heaty module. You then set heating circuits, zones and hot water on the SmartKnob or in the dashboard instead of on the heater's control panel.

Why Timberline is different from an air heater

Timberline is not just an air heater but a hybrid system: a diesel burner heats water, which runs through the vehicle via heating circuits, for example as underfloor heating. The same system also supplies hot water for the kitchen and bathroom at the same time.

The Timberline 2.0 works with two independent heating circuits and up to five zones. So you can keep the living area at a different temperature from the bathroom, or at night heat only where people are sleeping. This zone logic is exactly why a connection brings more here than with a simple air heater.

What you control via Camper Jarvis

  • Target temperature for each heating circuit and each zone
  • Hot water heating
  • Operating mode and system status in real time
  • Schedules and scenes, such as warming up the bathroom half an hour before you get up
  • Links with the rest of the system, such as lowering the temperature when the vehicle is empty

Everything runs locally in the vehicle, without cloud and without having to use an app. You operate it on the SmartKnob or in the dashboard on your phone or tablet, both equal and in sync.

You choose the temperature sensor

When you create the widget, you decide which sensor supplies the temperature. For example, the SmartKnob's internal sensor in the living area instead of a sensor on the heater. This way the control is based on the place where you actually are.

Using shore power

Timberline comes with a 230V electric heating element with 1.5kW. When the vehicle is on shore power, you can heat with it without using diesel. Combined with the shore power detection on Switchy, this can be automated.

What you need

  • A Heaty with the wiring harness for Timberline, which you choose when ordering
  • A SmartKnob as the centre of the system

The wiring harness is always included in the box. Heaty gets its power directly from the heater through it, so you do not need an additional power cable.

Related questions

Which heaters can I control with Heaty?

Heaty controls your existing parking heater directly, currently the Autoterm 2D and 4D, Timberline 1.0 and 2.0, the Webasto Air Top and the Eberspächer Airtronic S2 and S3. Heaty connects directly to the heater with the matching wiring harness, which is included. More Eberspächer heaters and air conditioners as well as Alde and Truma will follow. Instead of fiddling with your heater's small original control panel, you simply set temperature, timer and operating mode on the SmartKnob or in the dashboard. One control for everything in the van, without a brand-specific display or app.

Do I need a SmartKnob for Heaty to work?

Yes. Heaty is a module and connects to the SmartKnob, which is the hub of the system. Without a SmartKnob there is no user interface and there are no automations. If you already have one in your vehicle, you simply pair Heaty with it.

Is one Heaty enough for my whole camper?

One Heaty controls exactly one heater. If you have two separate parking heaters in your vehicle, each gets its own Heaty. In return, each one stays individually and cleanly controllable via the SmartKnob and fits perfectly into scenes and automations.

What is included with Heaty?

Everything you need to connect it: the Heaty module, the wiring harness for exactly the heater you select when ordering, and four mounting screws. Because the cable already fits your heater, installation is genuinely plug-and-play: no tinkering, no hunting for adapters.

Does Heaty need a separate power supply?

Usually not. The supplied wiring harness is designed so that Heaty gets its power directly from the heater. That saves you extra cables and valuable build time. The exception is the Timberline: there, Heaty needs its own additional 12V supply. Just plug it in: as soon as Heaty is supplied with power, it actively starts looking for a SmartKnob in pairing mode.

Does Heaty work on 12V and 24V?

Yes. Heaty works in the range from 9 to 36V, so it fits both 12V and 24V systems. It takes its power directly from the heater via the supplied wiring harness anyway.
