IV. Operation of the Controller
IVa) Operating Principle
The room regulator sends a signal on additional heating or underheating to the main controller.
Depending on the specific settings, the signal for additional heating of rooms may e.g.: switch off the
CH pump, reduce the set temperature of the boiler by the set one (settings can be adjusted with the
main controller). The room regulator also enables change of some settings within the main controller
e.g.: ability to change and set the temperature of the boiler, pump operation modes, etc.
IVb) Main Screen Description
The controller is equipped with a large touch-screen display. The main screen displays the current state
of basic parameters for the boiler.
Depending on the user's settings, the screen may display a visible installation screen or the panels
screen. Data which is displayed on the main screen of the room regulator depends on settings of the
main controller and its type.
NOTE
Each change of the set temperatures, time or other settings on the room regulator or boiler controller
introduces a new setting in both devices.
NOTE
Factory settings show the main screen as the installation screen which the user may change on the
panels screen.
