now it is implemented. Switzerland has switched off the 2G network on 01.01.2023. For iNet Box users in Switzerland the following applies:
You can still control and monitor the iNet Box and thus the connected devices via Bluetooth in the near field. The function via the far field via 2G (GSM) is no longer possible. Outside of Switzerland, e.g. on holiday in Italy, the GSM function is still available.
What is 2G and why is it being switched off? The term 2G refers to the GSM network. In other words, the network that is used to send a classic text message. You have certainly come across the names of the other networks before. For example, 3G corresponds to “UMTS” and 4G to “LTE”.
The 5G expansion is in full swing. This new, even faster network needs space. Therefore, one of the networks used so far will have to be shut down.
Are other countries besides Switzerland affected by this? Some European countries are planning to gradually shut down the 2G network. Liechtenstein is one of the next. However, since many systems in use are dependent on precisely this 2G network, the other European countries will continue to support this network. In Germany and Austria, the 3G network is therefore being switched off to make room for 5G. 2G will remain. So there will be no restrictions for the iNet Box in the near future.
Is there another Truma product for using a remote control in Switzerland? Unfortunately not at the moment. As of today, our iNet X system is purely Bluetooth-capable. This enables app control at close range. A module for remote control is planned and we are working on the corresponding implementation and production. Due to the current situation, we are unfortunately not yet able to give a concrete date. We will inform you as soon as the countdown begins.
As a camper, questions arise during the winter season such as: “How do I make sure that the water in my heating system or vehicle does not freeze when I am not on site during the day?” or “Can I heat my camper or caravan without water in the boiler?
We answer both questions in this article.
If you are travelling with your vehicle in winter, you can choose between the above options to suit your needs. Both are possible, as long as the operation of the unit is adapted accordingly.
Option 1: If your motorhome or caravan is filled with fresh water, the heating should always remain active. As long as the frost monitor of the Combi, the FrostControl (FC), is exposed to an ambient temperature of >3°C, it remains closed and the water remains in the system. It is important here that the temperature is measured directly at the FC. Experience has shown that it is equally important that only the water runs out of the Combi when the FC is open. Whether the fresh water tank and all water pipes also run empty depends on the installation of the water supply by the vehicle manufacturer. This may or may not be the case. You should check this at your leisure before starting your journey.
You can set 5°C as the lowest room temperature on the heating control. If this is not sufficient to heat the FC because it has been installed further away from the Combi or a warm air pipe, a higher room temperature requirement should be set. This is possible with the CP plus from 5°C in 1°C steps. Simply approach a suitable value slowly. With the CP classic, with the two rotary knobs, level 1 also corresponds to 5°C, level 5 about 30°C. The other levels are in between. Level 2 should therefore be sufficient to keep the FC closed. Please note that such operation is only recommended during a journey. It is not a suitable means of keeping the vehicle frost-free throughout the winter. Short heating times of the heater promote the formation of condensation in the exhaust tract.
If the installation space of the FrostControl is too far away from the heater or completely unheated, a separate heating element for the FC can be purchased from our authorised dealers.
Option 2: If you are travelling without water in the system, the Combi can also be operated. The only important thing here is to set only room heating as a requirement for the Combi. The water heating programme must remain inactive. Make sure that the water tank of the Combi is correctly emptied. Residual water in the combi can get very hot very quickly. The resulting water vapour can irritate the temperature sensors of the heater and lead to a warning message “Water overtemperature detected”. For this reason, we recommend that you leave the FC open when using the vehicle in this way. This way, the water can find its way out of every corner of the fresh water supply during a winding journey. Optionally, you can help by using light compressed air or a balloon that has been put over and filled at the open water taps.
Please note: we recommend both modes of operation only on one trip. Operating the heater in one of the specified options for months should be avoided. The reason for this is that this type of use does not correspond to the intended use of an appliance for camping needs. In addition, under unfavourable conditions, condensation can collect in the exhaust pipe and disrupt the proper operation of the heating system.
With these tips, you’ll be well prepared, even when it’s cold outside. We wish you a wonderful winter holiday.
Since the iOS13 release, connection problems between iPhone/iPad and the
Truma iNet Box occur. In the meantime, we have been able to identify two
different issues – but have not yet been able to solve the problems, even in
cooperation with Apple support.
Here you can find a detailed error description and technical information
about the causes of the problems. As soon as we have new findings, we will keep
you up to date in the Truma service blog and in the App News.
Have you had experiences that you would like to share
with other users and us? Then use the comment function in our service blog! We
look forward to exchanging ideas with you.
Then confirm or delete the fault code by tapping the rotary push button. Please note that the first tap might only activate the backlighting of the control panel.
The heating then starts automatically if there is a heating requirement.
Note: If the fault 507, 516 or 517 is displayed in the heater’s control panel, switching the control panel on and off does not help. This does not delete the fault, but blocks the heater for 15 minutes. The heater is also blocked for 15 minutes if the fault 507, 516 or 517 is deleted four times without the gas supply being established.
The fault code 507, 516 or 517 flashes because the heater is still in a 15-minute blocking time. This was possibly caused by the heater control panel being switched off or because the heater’s 12-Volt supply was interrupted. The heater is also blocked for 15 minutes if the displayed fault is deleted four times without the gas supply being restored.
Wait out the 15-minute blocking time for the heater. During this time, do not switch off the heater’s control panel and also do not interrupt the power supply.
As soon as the heater’s blocking time has expired, the fault is then displayed permanently rather than flashing. It can now be deleted as described in the point above.
Good news for Alde heater users. From April 2018, you will be able to integrate the Alde compact 3020 HE with new control panel into the Truma iNet System. All you have to do is connect the heater to the iNet Box.
This is great news above all for campers who use or would like to use a Truma air conditioning system or Truma LevelControl. You can now conveniently use all devices via the iNet System. From controlling the heater and air conditioning to using the automatic climate control and checking the gas level, all it takes is a single app.
The new version of the Truma App will be available from March 2018.
Important: Deactivate the automatic update function
Previously, Truma App users could download new releases to their smart phone and still have two months to install the new firmware onto the iNet Box via Bluetooth.
For the new update, the complexity of the project forced us to suspend this rule. This means that the two-month time frame does not apply for this release. You must update both your app and the iNet Box with the new firmware simultaneously.
If you have automatic updates activated in the Truma App, please deactivate this function and switch to manual updates. This will allow you to decide when you wish to install the update.
Otherwise, the app will perform the update automatically. If there is no Bluetooth connection to your iNet Box at this time, it will not be possible to update the firmware. The iNet Box will then no longer function until the new firmware is installed.
This is particularly important for campers who have parked their vehicle outside Bluetooth range and wish to use the iNet System.
For the next releases, the two-month time frame will apply as usual.

Replacement of the Truma gas outdoor socket and two gas valves
During the course of its quality assurance Truma has established that there may be leaks in the Truma gas outdoor socket and two gas removal valves. This only affects products with a yellow handle cap and the following codes below:
This can cause gas to leak uncontrollably from the affected products. In unfavourable circumstances this can lead to gas deflagration and injuries. We have not heard of such a case yet.
As a manufacturer of premium products, Truma attaches great importance to supplying reliable and safe products. The safety and well-being of our customers is our top priority which is why, to avoid any risk, we and our supplier have decided to replace all affected products. The probability that campers will encounter this fault is very low; nevertheless we would ask them to take the following precautions:
Ensure that the gas system is immediately turned off. To do this, close the cylinders and/or the gas tank or the external gas supply. If the external gas socket is connected to a separate shut-off valve (e.g. on the so-called valve block), you only need to close this shut-off valve.
If there is an awning, ensure good ventilation.
Check the code below the yellow handle cap (picture 1 below). To do this, you may have to turn the ring to read the code. Ensure that there are no ignition sources nearby during the inspection.
If your product has a code between …01.2016… and …01.2017…, please contact your dealer, a Truma Service Partner or the Truma Service Centre for a free replacement. The products may only be replaced by trained personnel; this process does not take very long. Do not use the gas system again or re-open the separate shut-off valve (e.g. on the so-called valve block) until the parts have been replaced!
If your product has a different code than those in the table above, the gas system is safe to use again.
You finally arrive at your holiday destination after a long journey. Now all you want to do is get the caravan set up and relax. If you want to position your caravan manually, you will need patience and high levels of physical strength. However, if you have a mover, you can simply manoeuvre your caravan safely into the correct position by remote control.
Gas cylinders have the annoying habit of becoming empty in the middle of the night. You can put a stop to this with the Truma DuoControl CS which automatically switches from the empty operating cylinder to the reserve.
The Truma dual-cylinder gas pressure regulator automatically switches to the reserve cylinder. The integrated crash sensor allows you to operate the gas system safely even when on the road.
