Heating mode

The control unit determines a set boiler water tempera-
ture subject to outside temperature or room tempera-
ture (if a room temperature-dependent remote control
is connected) and to the slope

/

level of the heating

curve.
The determined set boiler water temperature is trans-
ferred to the burner control unit. From the set and
actual boiler water temperatures, the burner control
unit calculates the modulation level and regulates the
burner accordingly.

The electronic temperature limiter inside the burner
control unit limits the boiler water temperature.

DHW heating with gas condensing combi boiler

If the flow switch detects that DHW is being drawn off
(

>

3 l/min), the burner, circulation pump and 3-way

valve are started or changed over. The burner modu-
lates to reach the DHW outlet temperature and is limi-
ted on the boiler side by the temperature limiter.

DHW heating with gas condensing boiler

The burner, the circulation pump and the 3-way valve
are started or changed over if the cylinder temperature
lies 2.5 K below the set cylinder temperature.

In the delivered condition, the set boiler water temper-
ature is 20 K above the set DHW temperature (adjust-
able via coding address "60" in group

"DHW"

(weather-compensated control units) or group 3 (con-
stant temperature control units). The burner will be
switched off and the circulation pump run-on time will
begin, if the actual cylinder temperature exceeds the
set cylinder temperature by 2.5 K.

Boosting DHW heating

This function is activated by specifying a second set
DHW temperature via coding address 58 in group

"DHW"

and activating the fourth DHW phase for DHW

heating.

Heating is boosted during the periods selected in this
time phase.
