The first digit shows the status of the boiler, the last 2 digits display the current flow temperature, except with
status 1, 2 or 5 when the number indicates the burner module about to start.
All other displays refer to error messages, see Frames 46 and 47 for details.

On/Off Switch

The on/off switch turns the mains power on/off within the
boiler. It does not isolate the boiler from the mains. Therefore
it is important that the boiler is isolated at the external mains
connection point before removing any casing panels.

Module and Reset Buttons

If a module locks out then its Reset Button becomes
illuminated. To reset the module you must hold down this
button whilst pressing the reset key.

Mode Key

The default mode of the boiler is standby. By pressing the
mode key it is possible to change the mode.
By pressing the mode key once, PARA mode (abbreviation for
parameter) is displayed. In this mode it is possible to change
the settings of the boiler control module. The first 3
parameters are accessible to all, and the remaining
parameters are accessible to an installer once he has
entered the service code.
By pressing the mode key again, DATA mode is displayed. In
this mode it is possible to read information on the operation of
the boiler.
