Safety devices
Air flow rate safety device
If an obstruction, even partial, of the flue occurs, the built in safety system of the boiler will turn the boiler OFF. The
boiler will be ready to operate when the fault has been cleared.
In case of power supply failure
The boiler no longer operates. As soon as power is restored, the boiler will be automatically restarted. If the boiler
does not restart, the overheat device may need resetting.
Overheat safety
In the event of overheating, the overheat safety device causes safety shutdown of the boiler. The digital display will
show error code F1. To reset, let the boiler cool down, press the reset button on the safety devices (a) and (c), see
diagram 22 and reset boiler controls by means of the reset button (8).
Note:
wire connections to overheat thermostat are mains voltage.
Important notice
A central heating system cannot operate satisfactorily unless it is properly filled
with water and unless the air initially contained in the pipework system has been
properly bled off. If these conditions are not satisfied, air noise will occur within the
system and the boiler may fail to operate.
To reset the boiler (other than for overheating) use the reset button on the fascia,
see diagram 15.
The
Protherm 80E
boiler has a built-in frost protection device that protects the
boiler during freezing conditions. This device works irrespective of any room ther-
mostat setting and only protects the boiler.
Should the temperature within the central heating circuit of the boiler fall below
10 °C, the pump will switch on providing the electrical supply has been left connect-
ed. If the temperature falls below 8 °C, then the burner will operate until the water temperature increases to 25 °C.
Should the electrical supply have been disconnected and the boiler/system has frozen, the boiler will not start up
until the boiler/system has been cleared.
