Note: in the case of simultaneous presence of outdoor temperature sensor and remote control, the electronic
board only sends the value of outdoor temperature to the remote device without using it for the modulation. The
remote device will use the value for modulation, if necessary. (See the manual of the remote).
The communication between the electronic board and the remote control takes place regardless of the mode of
operation selection made in the boiler, and once the connection is established, the onboard user interface is
