Paradigma S-Touch is a free app designed for iPhone users who own a heating system with a Paradigma heating controller SystaComfort II. This app allows users to conveniently operate their heating and solar systems from the comfort of their seat. Users can check temperatures, solar gains, set target values for rooms and domestic hot water, as well as turn the heating on and off.

The S-Touch app is also compatible with older SystaComfort II controllers, requiring a minimum application software version of V 1.18 or higher and a base system version of V 0.27 or higher to communicate with S-Touch. Users can update their software versions through their local Paradigma specialist.
