FUNCTIONAL ASPECTS NOT TO BE MISTAKEN FOR ANOMALIES
the following events may occur during normal operation:
a.
The compressor does not start up again immediately after a stop (it takes about three minutes
to start again).
-
in the operating logic of the appliance a delay between a compressor stop and its successive restart
has been included, so that the compressor itself is protected against activations that are too frequent.
b. During the heating operation of the heat pump appliances, the flow of hot air may occur some
minutes after activation of the compressor.
- Should the fan start at the same time as the compressor, for the first few minutes it would emit cold
air into the room (and this could bother the occupants) since the unit has not yet reached steady
running conditions.
c.
The two units UNICO MASTER and WALL cannot perform opposite modes of operation.
-
if one unit is working in cooling mode, the other unit cannot work in heating mode and vice versa.
Under all these conditions, the command will be refused by the Unit.
