Features and functions

The digital controller is a state of the art controller that offers full

heating only installation.
Both installations are available in multiple versions which vary in
capacity, electrical supply and installed equipment (with an optional
domestic hot water tank with a booster heater).
NOTE Descriptions in this manual that apply to a specific
installation or that depend on the installed
equipment, are marked with an asterisk (*).
Some functions described in this manual may not
