10.2.5 Hot water temperature

Use the minus button and the plus button to set the hot
water temperature. Confirm your setting with OK.

10.2.6 Comfort mode

Use the minus button and the plus button to enable or disa-
ble comfort mode. Confirm your setting with OK.

10.2.7 Heating partial load

The heating partial load of the Vaillant ecoTEC plus boiler is
factory set to "auto". This means that the boiler independ-
ently determines the optimum heating output depending on
the current heat demand of the system. A setting is nor-
mally no longer required.
The setting can also be changed later using diagnostics
point D.000.
i
If you have activated return control under D.17,
the automatic heating output determination
function is not active. If you set d.00 to "auto"
anyway, the boiler operates with the maximum
possible heating partial load.

Additional components that are attached to the boiler can
be adjusted directly here.
This setting can be changed using diagnostics codes D.026,
D.027 and D.028.

The operator can display these in the information menu.

right selector button.
