7.2 Particular operations
EVHP 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
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 these conditions are adequate for its
operation.
