The heating system must be kept pressurised [see "COMMISSIONING"
chapter – how to determine the operating pressure].
The hydraulic circuit pressure is permanently monitored by a pressure sensor.
If the pressure is less than 0.8 bar the display will show "LOP" (Low Pressure)
to indicate to you that filling of the hydraulic circuit is necessary.
For more information, please ask your installer when the system is delivered.
In the case of repeated fills, contact your installer.

FAulT:
The temperature setting of the appliance and the safety functions of the
boiler's various parts are constantly monitored by the "ESYS" system. If a fault
occurs, the ESYS turns the unit off and displays an error code: the screen flashes
and the first character is an "E" followed by the fault code.[see list of faults]
To reset the unit:
- Execute the "RESET" function by turning the domestic setting button
to the left up to minimum, then continue to turn the button lightly and
repeatedly for 3 seconds.
- If the fault code appears again, contact your installer.
