heating standby time, the message "d2".
Domestic hot water (DHW)
A DHW demand (generated by drawing domestic hot water) is indicated by flashing of
the hot water under the tap on the display.
The display (detail 11 - fig. 70) shows the actual DHW outlet temperature and, during
DHW standby time, the message "d1".
