3.3 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 /parameter 72) or set
manually by the installer (parameters 66).
If there are thermostatic valves on the installation, these
must be fully open or adjusted for higher than the normal
set temperature.
3.3.1 Manual adjustment
During installation, the temperature control must be
parametered according to the heat emitters and the
dwelling's insulation.
The temperature control' curves (gure 36) refer to an
ambient setting of 20°C.
The slope of the temperature control (parameter 66)
determines the impact of the variations in the outdoor
temperature on the initial heating temperature variations.
The off-set in the temperature control (parameter 68)
modies the initial temperature of all the curves, without
modication of the slope (gure 37).
The corrective actions in the case of any inconvenience
are detailed in the table (gure 38).
3.3.2 Self-adaptation
When this function is active (parameter 72), the
temperature control is automatically adjusted; it is
therefore futile to modify the slope or the off-set in the
temperature control (parameters 66 and 68).
When this function is rst 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 inuence of the ambient temperature (parameter 73)
must be set between 20 and 100% (depending on the
installation, the room thermostat may have a greater
or lesser inuence 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.
