The set temperature for heating decreases with the exterior
temperature, which allows the installation to operate at a low
temperature throughout the majority of the heating season and
improves the seasonal effi
ciency of the installation.
This function can be activated by setting
P231
to
AUTO
.
Setting the heat curve is done using parameters
P202
,
P203
,
P232
and
P233.

6.5 - Description of functionalities
6.5.1 - Functions related to heating
6.5.1.2 - Lowering of the temperature
The set temperature of heating can be lowered at the same time as
the ambient temperature when in Eco or Frost protection modes to
improve the heat pump’s performance.
The set temperature in comfort mode is the reference point. The
set temperature applied in Eco or Frost protection mode is the
temperature in comfort mode lowered by the diff erential:
-
P236
: lowering of the temperature in ECO mode.
-
P237
: lowering of the temperature in Frost protection mode.
6.5.1.3 - Auto-adaptability
The auto-adaptability function allows to continually correct the heat
curve to correspond to the needs of the household.
Auto-adaptability operates on two modes, which can be
independently activated:
• primary auto-adaptability (activated by
P238
) examines the heating
needs over 24h cycles and adjusts the set temperature for heating
when ambient temperature is requested.
• complementary auto-adaptability (activated by
P239
) examines
the heating needs over 3h cycles and adjusts the set temperature
when ambient temperature is not requested. Complementary
auto-adaptability requires the presence of an ambient temperature
sensor and the activation of the anti-cold radiators function
(
P234
=
2
).
6.5.1.4 - Ambient temperature reactivity
The reactivity function allows the pilot to increase its set temperature
for heating when the temperature read by the ambient temperature
sensor is far from the set temperature.
In particular, it allows an accelerated increase in ambient temperature
when returning to comfort mode.
This function is activated using parameter
P206
and requires the
presence of an ambient temperature sensor.
6.5.1.1 - AUTO temperature (heat curve)
Note:
In manual operation, it is possible for the user to set the set
temperature in the range of TCMI to TCMA.
6.5.2 - Programming and timeout functions
When this function is activated, the time of return from holiday
mode is no longer considered as the time for heating to resume,
but instead is considered as the time that the ambient temperature
should be at the set temperature. And so, the heating will resume in
advance based on the planned return from holiday mode.
This anticipation can vary based on if the heating circuit has a weak
inertia (
RADIAToR
setting) or strong inertia (
floor
setting). It also
depends on the exterior temperature read (advanced anticipation
on cold days).
The pilot uses a arbritrary initial time-delay which may cause
discomfort on the fi rst use of the function (fi rst return from holiday).
The length of anticipation is automatically adjusted after the fi rst use.
This function can be activated by setting parameter
P207
to
yes
.
