Technical Documentation
It is a clean contact switch that sends a signal (in low voltage) to
the board enabling functioning in the CH mode when the room
temperature is lower than that requested.
Room thermostat
(S20)
(external optional)
Open = Central
heating OFF
Closed = Central
heating ON
It is a contact which, on opening, allows the board to identify and
display any flue safety thermostat intervention (E6) with an "ERR
03" error code.
Flue safety thermostat
(E6)
Open = Functio-
ning OFF
Closed = Functio-
ning ON
It is a resistance that can be varied proportionally to the external
temperature.
It allows the integrated P.C.B. to vary the system flow temperature
depending on the external temperature.
External probe (B4)
(optional)
PTC probe
1 kΩ 25 °C
It is a resistance that can be varied in an inversely proportional
manner to the temperature of the primary circuit flow water.
It is also used as a limit thermostat on the flow (90 °C).
Flow probe
(B1)
NTC probe
10 kΩ 25 °C
It is a resistance that can be varied in an inversely proportional
manner to the temperature of the water contained in the storage
tank.
Domestic hot water probe
(B2)
NTC probe
10 kΩ 25 °C
It is a resistance that can be varied in an inversely proportional
manner to the temperature of the primary circuit return water.
Return probe
(B5)
NTC probe
10 kΩ 25 °C
It is a contact which, on opening, allows the board to identify and
display any flue safety thermostat intervention (E4) with an "ERR
02" error code.
Safety thermostat
(E4)
Open = Functio-
ning OFF
Closed = Functio-
ning ON
It is a square wave signal detected with a Hall effect sensor inserted into the fan. It allows
the integrated P.C.B. to measure the speed and correct it if it does not comply with the
requested value.
