DCPX
This accessory allows correct operation with outside temperatures below
10°C and down to -10°C.
It is made up of an electronic regulation card that varies the fan rpm on the
basis of the condensation pressure (read by the high pressure
transducer), to keep it sufficiently high for the proper functioning of the unit.
It also allows correct heating operation with outside temperatures greater
than 30°C and up to 42°C.
