Before making connections
make sure you have
correctly sized
the section of the power cables
based on the actual distance
from the counter.

A) Heat pump only operation
The key on the left of the figure must be in the OFF position "0 key",
in this way the electric resistance will never work
B) Resistance heat pump operation
To use the integration resistance just press the left button
in the ON position " I key"
and the one on the right in the INTEGRATION position "key II ".
In this way, the control unit will decide when help is needed
of the resistance that will work in conjunction with the heat pump.
Resistance only operation.
To use only the resistor instead of the heat pump,
just press the left button in the ON position “ I button” and the right one
in the EMERGENCY “button I ” position.
