Particular operations

The product has a fan speed control system that
increases the speed of the same, when the
ambient temperature drops to below -1°C, at
higher temperatures, the fan maintains a lower
speed in order to reducing the noise of the
equipment.
The equipment is also provided with a verification
system of the environmental conditions concerning
the temperatures of the external incoming air. The
below described function is necessary to avoid the
equipment working with the heat pump mode out
of specification, which may cause faults to the
compressor and the consequent interruption of the
functionality.
By every start, the fan is activated for a time set up
by parameter C12 corresponding to 1 minute.
After this time, the system measures the incoming
air temperature. If the temperature is equal to or
lower than parameter SP9 (-7°C), then the
conditions for the activation of the heat pump unit
are not met, therefore the electric resistance is
activated. The heating-up process continues with
the help of the electrical resistance until the set
point established with the ongoing active cycle is
reached.
The system verifies cyclically (every 120 minutes)
the environmental conditions and activates the
heat pump mode only when this conditions are
adequate for its operation.
