Safety and control devices
The control panel, apart from managing the functions of the
thermal unit
ACQUAHOME R BLU
, allows to highlight any anom-
aly which may affect its correct operation, ensuring the thermal
unit safety by stopping it and automatically closing the burner
light oil valve.
The burner control and adjustment board is also used to en-
sure the burner safety by managing its correct operation.
Any anomaly which may affect the generator operation forces
it to stop (lock-out) and is promptly signalled with a numerical
error code on the regulator display.
The following are installed on the water circuit:
-
Safety thermostat
: fitted on the generator body, it inter-
venes by stopping (permanent error) the thermal unit
if the boiler temperature exceeds the limit threshold of
110°C;
-
Safety valve
: intervenes if the boiler pressure exceeds
the limit threshold of 3 bar;
-
Pressure transducer
: sends a signal to the electron-
ic regulator which views and continually checks the
primary circuit pressure to switch on the generator or
cause it to stop in case of low pressure;
-
Boiler temperature probes (delivery and return)
: immer-
sion probe on the delivery line of the generator is used
by the regulator to view and check the delivery water
temperature and check the correct switching on and off
of the burner based on the programmed setpoint. The
regulator uses the same probe to switch off the genera-
tor in case of overtemperature, before the triggering of
the safety thermostat. The contact probe placed on the
return line of the boiler is used by the regulator to view
the return water temperature with which it calculates,
together with the delivery temperature, the temperature
difference between delivery and return (
∆
t), which al-
lows regulating the modulation of the circulator in heat-
ing mode.
b
The intervention of a safety device indicates a potentially
dangerous malfunction in the system. Contact the manu-
facturer’s Technical Assistance Centre immediately.
b
Safety devices must only be replaced by the manufac-
turer's Technical Assistance Centre using original spare
parts. Refer to the spare parts catalogue supplied with
the boiler. After making the repair, check that the appli-
ance is working properly.
a
The appliance must not be put in service, even temporar-
ily, when tampered safety devices are not in operation or
have been tampered with.
