Connection of external probe or thermostat

To manage the boiler using an external thermostat (optional), connect it to the appropriate terminals on the board, as shown in the
⚠
Electric scheme.
⚠
Connect an open/closed external thermostat, therefore potential-free.
If you intend to use the "comfort clima" function, we recommend you use a thermostat with a minimum offset of 3°C.

Testing and commissioning

Boiler start-up must be preceded by testing, which includes an operational check of the following elements:
•
connection to the smoke evacuation system;
•
electrical connections;
•
hydraulic connections;
•
operation of any connected external probes;
•
checking that all materials used to build the smoke duct, chimney and chimney pot are regulation and suitable for use.
The testing is positive only when all operational phases have been completed without any anomaly being detected.
