Operating the heating system

Maximum CH (boiler) flow temperature dial
The maximum CH (boiler) flow temperature ( fig. 4, item 8) is used to
set the upper CH (boiler) flow temperature limit. The unit is °C.
DANGER: Damage to the installation with underfloor
heating: by the floor being overheated.
▶ Limit the maximum CH (boiler) flow temperature
using the "CH (boiler) flow temperature" dial
( fig. 4, item 8) to the permissible flow
temperature of the floor heating circuit (usually
maximum 40 °C).
Display
The heating system status and values can be read out from the display
( fig. 4, item 9). If a fault occurs the display will immediately show the
accompanying fault code. The fault code display will flash if a locking
fault is detected.

has occurred and it is extinguished when this DHW request is no longer
required.
DHW temperature dial
The DHW temperature dial ( fig. 4, item 11) is used to select the
required temperature of the hot water in the hot water cylinder. The unit
is °C. This is only active with certain Bosch controls.
