Boiler control
A) REPLACEMENT:
the boiler is only enabled if the outside
air temperature is less than the value of parameter 0307
and the compressor is off, figure 3.
To enable boiler activation in REPLACEMENT mode set
parameter 0306=1 and 010H = 1
Boiler operation reflects the trend in water temperature, as
shown on the graph in figure 4.
If the heat pump shuts down due to an alarm the boiler is
activated automatically regardless of the outside air temper-
ature.
In REPLACEMENT mode the activation delay time is
ignored, and the boiler is activated immediately if necessary.

B) SUPPLEMENTARY:
the boiler operates in supplemen-
tary heating mode, together with the compressor, to satisfy
the heating load.
Supplementary heating for low outside air temperature
The boiler is enabled only when the outside air temperature
is less than the value of parameter 0307, figure 3.
To enable the supplementary heating for outside air temper-
ature set parameter 0306 = 1 and 010H = 0
Boiler operation reflects the trend in water temperature, as
shown on the graph in figure 4.
