Safety and control devices
The control panel, apart from managing the functions of the
thermal unit INSIEME EVOe 32 B/110 LN, allows to highlight any
anomaly 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 ensure
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 in-
tervenes 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 electronic reg-
ulator 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): im-
mersion probe on the delivery line of the generator is
used by the regulator to view and check the delivery wa-
ter 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 allows
regulating the modulation of the circulator in heating
mode.
− Domestic circuit temperature probe (heater): the im-
mersion probe in the heater is used by the regulator to
view and check the domestic hot water temperature and
to manage the relevant operating parameters (DHW Set-
point, DHW request, etc.).

The intervention of a safety device indicates a potentially
dangerous malfunction in the system. Contact the manu-
facturer's Technical Assistance Service immediately.
9
Safety devices must only be replaced by the manufactur-
er's Technical Assistance Service using original spare parts.
Refer to the spare parts catalogue supplied with the boiler.
After making the repair, check that the appliance is working
properly.
0
The appliance must not be put in service, even temporarily,
when tampered safety devices are not in operation or have
been tampered with.
Always check that the boiler is functioning correctly after repairs
have been made.
