CONNECTING THE AMBIENT THERMOSTAT
• access the power supply terminal block (figure 10);
• connect the terminals of the ambient thermostat to clamps (1) and (2);
• power the boiler.
OPERATION OF BUTTON
The button is no longer operative as described in section 4.1 (ECONOMY-COMFORT function).
The boiler supplies heat to the heating system only when the time band programmed by the user and the ambient ther-
mostat are both in request mode.
By pressing the button it is possible to enable boiler operation when the ambient thermostat is in request mode
but the programmed time band does not request heat (manual "forcing"). In this case the display of the climate controller
shows the blinking symbol Operation in manual mode ends at the next time band that does not request heat in heating.
