Almost too good to hide away in a boiler: the Vaillant calorMATIC 470 system controller with its sleek black finish and platinum-colored brand shield is at the heart of every Vaillant heating system. Whether it is directly integrated into the boiler or installed in the living room, this handy helper adjusts the room temperature subject to both the external temperature and the user’s daily habits. This means that the heating appliance is only activated when heat is needed, conserving natural resources. The user can quickly and intuitively set their new chosen temperature with the aid of the plain text display and a turn of the dial.
