the boiler can be used, with the application of a generic external control
(chronothermostat) or another type of control provided that it is voltage-free
(dry contact). Note: The external control normally comes with a manual. The
thermostat must have a 1 to 2°C hysteresis;

The parameter for operation of the room thermostat in this hydraulic scheme
is
A01= 04
;
-
The first activation must be done manually on the display (put the boiler in
standby);

domestic hot water probe to the boiler, always proceed as follows:
1.
The boiler must be in the Off position.
2.
Disconnect the boiler from the mains supply.
3.
Connect the S3 probe at the rear of the boiler.
4.
Reconnect the mains supply.
5.
The electronics will give an error (

6.
Unlock the error and the electronic system will automatically recognise the
new configuration.
