Adjusting the central heating output
(range rating)
The boilers are fully modulating for central heating, and
it is therefore not necessary to range rate the boiler.
However, if desired, it is possible to range rate the
boiler, as follows:
• Press the “i” and “+” buttons simultaneously.
• Keep the “+” button pressed until “d.0” is displayed.
Note
The display runs from “d.0” to “d.99” before
restarting at “d.0”.
• Press the “i” button. The “=” symbol is displayed.
The part load setting is now displayed in kW.
• Use the “+” and “–” buttons to increase or decrease
the value in steps of 1 kW. The displayed value will
flash while the adjustment procedure is being carried
out. The available ranges of settings are given in
Table 5.3.
• Push the “i” button for about five seconds, or until the
display stops flashing. The value is now saved to
memory. The display will now return to its normal
state (current heating system flow temperature, e.g.
45 °C).
• Press the “i” and “+” buttons simultaneously to cancel
adjustment mode.
Adjustment mode is also cancelled if no button is
operated for a period of 4 minutes.
