INSTRUCTIONS FOR FITTERS
CONNECTING THE AMBIENT THERMOSTAT
• access the power supply terminal block (figure 10);
• connect the ambient thermostat terminals to terminals (1) and (2);
• power the boiler;
Operation of key
The key
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 thermostat are both
requested.
By pressing the key
it is possible to enable boiler operation when the ambient thermostat is requested but the programmed time
band does not require heat (manual “forcing”). In this case the display of the climate controller shows the flashing symbol Manual
operation ends at the next time band when heat is not requested in heating.
IMPORTANT:
After installing the climate controller, power the appliance and make sure the former works correctly.
To mount the climate controller on the wall, proceed as follows:
1.
Unscrew the two screws (
a-b
figure 11) that fix the casing to the boiler;
2.
Access the
M2
terminal block, as illustrated in the figure below;
3.
remove the two red wires from the terminals
1-2
and connect the two wires from the climate controller.
4.
insert the climate controller in the housing provided on the dashboard of the front panel without applying excessive force;
