If you have an old Compact P multi unit, perhaps combined with GEO or AIR, you can upgrade the old control panel to a new, modern touch panel.
The main screen of the CTS700 touch panel displays more user information. It is also possible to set the most common settings on the main screen. The structure of the menu and the informative text material make it easy to navigate.
The upgrade to CTS700 touch panel includes installation of the latest software version that has new functions. You should therefore get an installer to install the upgrade kit, and not attempt to do so yourself.
