operation very quiet at part load. An
electronic control varies the speed of
the condensing vantilatori according
to condensing pressure, which has a
special transducer, ensuring proper
supply to the thermostatic valve. his
accessory ensures the correct opera-
tion at external temperatures lower
than 20 °C down to – 10 °C. It con-
sists of an electronic control card
which adjusts fan speed according
to the condensation pressure read by
accessory TP2 (high pressure tran-
sducer, supplied in conjunction with
accessory DCPX) in order to keep the
pressure sufficiently high to supply the
thermostat valve correctly.
