With the setting --°C, the value calculated via the heating curve is used as
the flow setpoint.
Swi-on ratio room stat (744, 1044, 1344)
The boiler tries to adapt the flow temperature so that the switch-on ratio
set under this parameter is achieved by the ambient thermostats
Delay heat request (746, 1046, 1346)
The boiler heat request is forwarded to the burner delayed by the time set
here. In this way a slowly opening mixer can already start up before the
burner goes into operation.
Important
If the option Absolute is selected under prog.no. 1630, the value 0
must be set under this prog.no. For special functions (e.g.
chimney-sweep function) the delay does not have an effect (see
prog.no. 2470).

Room influence (750, 1050, 1350)
The flow temperature is calculated by means of the heating curve subject
to outside temperature. This type of control assumes that the heating
curve is set correctly, since room temperature is not taken into
consideration with this setting.
Important
However, if there is a room unit (e.g. RGP) is connected and the
setting "room influence" is set between 1 and 99%, the deviation
of the room temperature compared to the set point is recorded
and taken into consideration in the temperature control. In this
way any external heat can be taken into account enabling a
constant room temperature to be achieved. The influence of the
deviation can be set in percentage. The more representative the
lead room is (correct room temperature, correct installation
location etc.), the higher the value can be set, giving the room
temperature even greater relevance.
Caution
Should there be radiator valves in the lead room (where the room
sensor is installed), they must be opened fully.

0 Off
The heating circuit pump is switched on or off subject to room temperature
in line with the switching differential set here. The switch-off point of the
pump is set as the difference to the set room setpoint. The pump switch-
on point is 0.25 °C below the room setpoint. This function is only possible
with a room device (e.g. RGP) and active room influence.
Important
A room sensor must be connected. This function only applies to
pumped heating circuits.
