Flow temp setpoint min/ max
Using this limitation, a temperature
range for the flow temperature setpoint
can be defined. If the flow temperature
setpoint demanded by the heating
circuit reaches the relevant limit and
the heat request increases or
decreases, the flow temperature
setpoint will be maintained at the
maximum or minimum limit.
Room influence
Type of compensation
When a room temperature sensor is
used, there is a choice of 3 different
types of compensation.

Pure weather compensation
The flow temperature is calculated via
the heating curve, depending on the
composite outside temperature. This
type of compensation calls for a correct
adjustment of the heating curve, since
in this case the control gives no
consideration to the room temperature.
Weather compensation with room
influence
Deviations of the actual room
temperature from the setpoint are
acquired and taken into account when
controlling the temperature. Heat gains
can thus be considered, facilitating more
accurate room temperature control. The
authority of deviation is set as a
percentage figure. The better the
reference room (correct room
temperature, correct mounting location,
etc.) the higher the value can be set.
Example:
60 % Good reference room conditions
20 % Unfavorable reference room
To activate the function, following must
be considered:
 A room sensor must be connected
 Room influence must be set to a
value between 1 and 99 %
 There should be no thermostatic
radiator valves in the reference
room (mounting location of the
room sensor). If such valves are
present, they must be set to their
fully open position.
Pure room compensation
The flow temperature is controlled
depending on the room temperature
setpoint, the current room
temperature and the progression of
the room temperature. For example,
a slight increase of the room
temperature causes an immediate
drop of the following temperature.
To activate the function, following must
be considered:
 A room sensor must be connected
 Room influence must be set to
100 %
 There should be no thermostatic
radiator valves in the reference room
(mounting location of the room
sensor). If such valves are present,
they must be set to their fully open
position.
