Good news if you have the new Truma touch screen. We retroffited this back in October. Currently in the C&MC site in Sandringham and woke up to the dawn chorus and a nice little surprise from Truma in the shape of an update containing a timer function. This was strangely omitted when the touch screen was released but now you can have the convenience of setting up to six timer functions, enabling you to come back from a day out to hot water and/or heating. So if you have the touch screen and haven't connected with your phones Bluetooth in a while, now's the time to do it and get this really useful update.
