The maximum output of the boiler during DHW production as a
percentage of the maximum available output
The minimum heat output of the boiler during DHW and CH
production as a percentage of the available heat output
The maximum output of the boiler during CH production as a
percentage of the naximum available output

0 = Off
1 = Main zone control (with Climatic controller)
2 = General alarm
3 = CH phase active (external pump)
4 = External gas valve power supply
5 = Flow Smart enabled

9 = When boiler pump active
The pump can function in two ways.
0 Intermittent - In Winter mode the pump is managed by the
room thermostat or by the remote control
1 Continuous - In Winter mode the pump is always on
If the reading of the external sensor is incorrect it is possible to
offset the reading.
(Over the value of +9 the display shows 'CE', for external control
connection only used with system supervisor connection)
