Heating system water pressure reading
The analogue hydrometer on the control panel has a bar dial from 0 to 6 bar. The current
central heating system water pressure is indicated by the black needle. The optimum
central heating system water pressure is between 1 and 1.5 bar. The pressure can exceed
1.5 bar, to a maximum of 2 bar (maximum expansion of the system during a temperature
rise). Pressures over 2 bar are not within the operating range of the appliance. When this
level is exceeded, the action of the pressure transducer will cause the display of the
"
ERROR F 10
" error message and the boiler will remain in operation. However, if the
threshold of 2.8 bar is exceeded, the system stops until the pressure falls back within the
allowed range. The minimum operating pressure is 0.8 bar (+/-0.2 bar). If the pressure
detected by the transducer is less than 0.7 bar, the "
ERROR F 1
" message appears
and the operation of the system stops. The last safety feature of the boiler is the
mechanical valve, which when a pressure of 3 bar is reached starts to release water
through the
VSR
drain, the position of which can be found in the hydraulic connection
diagram (see page
5
).
