iOS13 connection problems

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.

Posted on 28. November 2019 by Monika Prandl

Service technicians on hand at six winter camp sites

Winter camping has its own special charm when it’s icy outside and snug and warm inside. But what if the heater breaks down? That would soon put an end to any holiday plans. But Truma makes sure that doesn’t happen. From 21 to 31 Dec. 2019 Truma service technicians will be on hand at six winter camp sites in Germany, Austria and Italy. Truma Service has a long tradition of being available over Christmas and New Year. “Our heating systems are very reliable,” says Service Manager Michael Suckart. “But just in case, our Service professionals are on hand so that our customers can enjoy carefree holidays.” As well as repairing appliances, the Truma experts give advice and answer questions about all our products.

The fault 507, 516 or 517 appears in the display of the digital control panel CP plus – what to do

Remote control Truma CP plus

Remedy fault 507 / 516 / 517 (gas supply interrupted)

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.


Remedying flashing fault 507 / 516 / 517 (gas supply interrupted)

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.
