I A
B) SUPPLEMENTARY:
the electric heater operates in sup-
plementary heating mode, together with the compressor, to
satisfy the heating load.
Supplementary heating for low outside air temperature
The electric heater is enabled only when the outside tem-
perature is less than the value of parameter 0304, figure 3.
To enable supplementary heating for low outside air temper-
ature set parameter 0303 = 1 and 010G = 0
Electric heater operation reflects the trend in water outlet
temperature, as shown on the graph in figure 4.

Outlet electric heater control
A) REPLACEMENT:
The electric heater is enabled when
the outside temperature is less than the value of parameter
0304 and the compressor is off, figure 3.
To enable heater activation in REPLACEMENT mode set
parameter 0303 = 1 and 010G = 1.
Electric heater operation reflects the trend in water outlet
temperature, as shown on the graph in figure 4.
If the heat pump shuts down due to an alarm, the electric
heater is activated automatically regardless of the outside
air temperature.
In REPLACEMENT mode the electric heater activation
delay time is ignored, and the device is activated immediate-
ly if necessary.
