6.1.2 Four-point characteristic
The four-point characteristic allows you to define your own heating characteristic.
It is defined by four points for 'Outdoor temperature', 'Flow temperature', 'Reduced flow temper-
ature' and 'Return flow temperature'. The 'Max. flow temperature' and 'Min. flow temperature' pa-
rameters mark the upper and lower limits of the flow temperature.
Note:
–
The HC1 flow temperature set points can be raised or reduced by 2 K in four stages even
when the four-point characteristic is selected. The room temperature set points for day
and night must be set (
→
Section 3.1) if the supplementary functions, such as
Optimiza-
tion
or
Flash adaptation
(the room temperature must be measured for both these func-
tions), are configured.
–
The
four-point characteristic
function can only be activated when the
Adaptation
function
is not active.
