Yup my Max! devices do that as I believe do the more modern Homematic valves. Every week, they go from one extreme valve position to the other and then go back to where they were before. As E1cid said, it's to stop the valves gumming up in the summer when they might otherwise go for months without moving. I can set what time of day they do it.
