(in combination with an external hot water cylinder).

The current setting blinks.
Use the C and D keys to adjust to desired setting.
Central heating is on.
Central heating is off (summer operation).

external hot water cylinder).
NOTE
When summer operation is active then the
boiler will not operate for central heating until
summer operation has been deactivated.
Setting the flow temperature for CH
Press E button (see fig. 6, item 2) three times then adjust
the flow temperature to the desired temperature (30 °C –
80 °C) using the C and D keys (see fig. 6, item 1).
