Truma iNet System

Mornings in bed, afternoons at the beach or evenings in a restaurant: thanks to the Truma iNet System, you can control your Truma appliances conveniently with the App at any time, no matter where you are.

Truma air conditioners that are compatible with the iNet System

It couldn’t be easier: While you’re relaxing on your lounger at the beach, you can switch on the air conditioner in your caravan from the App. No matter whether you own an Aventa roof-mounted air conditioner or a Saphir storage box system: these systems are compatible with the Truma iNet System.

How the Truma iNet System works

The Truma iNet Box is the central control unit for your Truma appliances. It connects the air conditioner and heater with your smartphone, receives the control commands and routes them to the appliances. The control is via SMS, or Bluetooth if the appliance is within range.

Control your air conditioning and heating systems with the free Truma App. Enjoy automatic climate control by combining a Combi heater with a Truma air conditioner. You can also operate two different Truma air conditioners in a Truma iNet System.

Enthusiastic customers

The Truma App makes us completely independent: We can simply activate the heating system from the ski slopes … and can enjoy the cosy warmth in the vehicle when we get back!

Thanks to the iNet System we always have a constant pleasant temperature in the vehicle. The heater and air-con regulate themselves automatically!

It is very practical that I can heat up the caravan at short notice after I’ve been diving.

Andrea, caravan

We are usually far away from the bus when we go climbing. So, the remote controlled heater is very practical!

Sylvia and Maria, camping bus

To save energy we want to be able to switch on the air-con from the beach at short notice.

Silvana and Jan, caravan

I like to check my gas supply using the Truma App and always know how long the remaining gas will last, whatever the time of the day and wherever I am. Ingenious!
