Setting the slope of heating
3 2 1 Temperature control
The heat pump's operation is subject to the temperature
control.
The set temperature for the water in the heating circuit
is adjusted according to the outdoor temperature.
The temperature control may be chosen automatically
by the machine (self-adaptation) or set manually by the
installer (Parameters 720, 721 and 726).
If there are thermostatic valves on the installation, these
must be fully open or adjusted for higher than the normal
set temperature.
3 2 2 Manual adjustment
During installation, the temperature control must be
parametered according to the heat emitters and the
dwelling's insulation.
The temperature control' curves
ambient setting of 20°C.
The slope of the temperature control (parameter 720)
determines the impact of the variations in the outdoor
temperature on the initial heating temperature variations.
The higher the slope, the more a slight reduction in the
outdoor temperature causes a significant increase in
the flow water temperature in the heating circuit.
The off-set in the temperature control (parameter 721)
modifies the initial temperature of all the curves, without
modification of the slope

3 2 3 Self-adaptation
When this function is active (parameter 726), the
temperature control is automatically adjusted; it is
therefore futile to modify the slope or the off-set in the
temperature control (parameters 720 and 721).
When this function is first activated, the end user
may experience some inconvenience for a few days.
This period of no more than a week is required by
the regulator to determine the slope and off-set in the
temperature control. We advise against changing the
temperature settings during this period.
The following instructions must be observed for the
self-adaptation system to operate correctly :
- A room thermostat must be connected.
- The
influence
of
(parameter 750) must be set between 1 and 100%.
- Depending on the installation, the room thermostat may
have a greater or lesser influence on the temperature
control. The room in which the room thermostat is
installed must not contain any thermostatic valves.
If this is the case, the valves must be open fully.
