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.
If there are thermostatic valves on the installation, these
must be fully open or adjusted for higher than the normal
set temperature.

7 .3 .1 Set to

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
The corrective actions in the case of any inconvenience
are detailed in the table
