Ideal interface with equipment, with many different options for timing functions and disabling functions. Still trying to find out how to disable the bleep whenever you do anything on the control panel....

Great app and great product. I am using it for over 2 years, very efficient. And I can control temperature, timer etc. from my mobile

It is the app is not nearly as good as the old app ant too hard to read the small print and to set one off times GO BACK TO THE ORIGINAL APP

For convection heater - app displays extremely small size numbers for the "current" temperature while "set" temperature has huge numbers. Madness.
★★★★★Andrew Faulkner· Oct 14, 2024
Just have to set all to manual if using the program side else it always defaults to 21⁰c

Absolute waste of space. The app has a mind of its own. It turns the device on and off arbitrarily and sets whatever temperature it wants. Set a manual operation, and you can't get back to automatic mode without creating a new scheduled automatic event. Clicking cancel or automatic on the limited menu does nothing. It completely ruins the use of the device, which is also pretty useless, even in a small bathroom, failing to get a temperature higher than 18⁰ or 19⁰ if you leave it on for 3 hours.

App only works for remote operating "live". When I add on/off schedules for my Bornholm heaters they stop working completely. Power them off, they work again until the next schedule, then they fail again.

Dear Klansman management. Making a rollback to old version of your app would be the best thing you could do. You can read all the problems in the comments here. Mine is that I do not see the actual temperature of heaters on the homepage. The only way how to get the temp is to turn each heater, read it and turn it off. User comfort dropped on a scale from 1-10 from 7 to 0 (zero). I wrote feedback in the app with no response since 16.12.23. Congrats. Now I will share my experience everywhere I can.
