Truma App Version (4.15.3) only for Android

After the last update, there was a functional restriction with individual Android devices (including Xiaomi). Unfortunately, the solution was not trivial and more complex than expected.

But now the time has come and we have a solution. The public test version is available here via the Google Play Store. The full release will follow shortly.

We sincerely apologise for any inconvenience and would appreciate any feedback on this version.

Best regards and have a great start into May!

2G switch-off in Switzerland – consequences for the iNet Box

Hello all,

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.

As you have surely followed, we have been informing about this topic for several years –> Service blog article from August 2020

Here are the answers to the questions that arise:

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.

Movers for caravans: what is important

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.

No more empty gas cylinders

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.

SolarSet 23: Protecting the battery against deep discharging

A reliable power supply is imperative if you want to make sure manoeuvring your caravan with the Truma Mover® is possible at any time. In conjunction with the Mover® PowerSet, the Truma SolarSet 23 protects the battery of the Truma Mover® against deep discharging. The set also maintains the voltage in the battery, even when it is overcast outside.

Truma Solarset

It is important to keep the battery of the Truma Mover® PowerSet fully charged because the SolarSet23 is only suitable for maintaining the charging level. The Truma BC10 charger is ideal for gentle charging. 

Deep discharging and its consequences

The battery has deep discharged, if the battery voltage drops below 10.8 Volt, i.e. more capacity has been drawn from the battery than allowed. The battery capacity should not drop below 70 percent; this ensures a long service life that is measured in charging cycles.

The following factors can lead to deep discharging: Continue reading

CP-plus digital control unit also for air-conditioning Saphir Compact/Comfort RC

The digital control unit

can not only be used for our heater type Combi 4 or Combi 6 (gas/electro- or dieselversion), but is also compatible with our air-conditioning system Saphir Compact  and Comfort RC.

It must be notified, that the air-conditioning System Saphir Compact can only be operated with the digital control unit with serial-number 23091001 or higher. Otherwise the electronik must be changed in adition.

Heat exchanger

Replacement of the heat exchanger is not necessary for Truma liquid gas heaters

Worried customers frequently ask us about the regulation that stipulates that heat exchangers in vehicle heaters need to be replaced after 10 years.

Here is our detailed explanation: (This can also be submitted to the TÜV/Dekra if they do not have a copy.)
In compliance with the Road Traffic Regulations “Technical requirements for vehicle parts for the type test in compliance with §22a StVZO” dated 05.07.1973 for heaters operated with liquid fuels (diesel, petrol), the heat exchanger must be replaced after 10 years of use.

The reason for this are combustion residues.

In the new version of these “Technical requirements” dated 19.03.1990 the Federal Motor Vehicle and Transport Authority also demands the replacement of the heat exchanger in heaters operated with gaseous fuels after 10 years.

However when liquid gas is combusted, no corrosive elements are created that could corrode the heat exchanger of the liquid gas heaters, so that for reasons of safety, a replacement of the heat exchanger is not necessary.
Knowing this, we are convinced that the safety and quality of the Truma products can always be guaranteed well beyond 10 years, which is why we decided to prevent the enactment of the new version of the “Technical requirements” for the benefit of our customers!

We commissioned a technical report on corrosion to assess the durability of Truma liquid gas heaters from the Research and Material Testing Institute for Civil Engineering, Corrosion Protection department, which came to a very clear result: “Heaters of this type can be operated without problems for 30 years or more, without any signs of leaks caused by corrosion”.

Based on this report we were able to convince the Motor Vehicle and Transport Authority to extend the periods of use of the heat exchangers in liquid gas heaters and the exhaust-carrying pipes from 10 to 30 years in the “Technical requirements for vehicle parts in compliance with §22a StVZO”.

This means that these costly replacements that have no technical relevance and do not benefit the customer are no longer necessary.

This now means that anyone who has installed a Truma liquid gas heater Trumatic C, E or S-K in their motorcaravan is freed of their duty to replace the heater exchangers and exhaust pipes over the next years.

Note:

The heater exchangers/combustion chambers in heaters in motor vehicles (lorries and motorcaravan) that were built between 1993 and 2006 must be replaced (after 30 years).
Older heaters have permission to operate in non-compliance and newer vehicle have an E1 code that relieves them of this duty. Example: A replacement duty for e.g. the year of construction 1993 would then come into effect in 2023.
The heat exchangers in caravans are not affected by this regulation.

Diagnosis – frost damage

Maybe the one or other Camper has made the not so nice experience of a leaking waterheater when started up for the first time after the winter.

A reason for this could be that the water was not drained from the waterheater. Or there was still water in the lines that had not been completely emptied because e.g. the caravan was not positioned horizontally.

Always empty the boiler if the vehicle is not in use during periods of frost.

To avoid frost damage to the waterheater, we advise the following:

1. The caravan should be positioned horizontally when draining the water.
2. First disconnect the power supply to the water pump (master switch of transformer)
3. Next, the water is drained from the tank and / or the water pump is removed from the tank.
4. Now open the taps in the kitchen and wet cell, and if your vehicle has pre-mixing valves, set these to warm.
5. Then turn to completely open the drain and venting valve, and pull out.
6. Now check whether the water (5 litres) drains completely.
Our tip:
Use a 5 litre bucket or tank with a filling level scale to check the amount of drained water.
7. You can also blow into the open tap – when set to warm – to blow out any remaining water from the device.

And finally, another bit of advice!
We recommend using agents with active oxygen and silver ions for cleaning, disinfection and care tasks . These disinfect effectively and are gentle on materials and the environment.
