PQ Remote display: Remote terminal, allowing to display the temperature values detected by probes, the alarm digital inputs, the outputs and the
remote ON/OFF of the unit, as well as to change and programs the parameters, and to signal and display any occurred alarm.
PW Part-Winding:Equipment for step compressors starting, reducing compressor inrush current.
RA Anti-freezeheateronevaporator: Electrical heater installed on the evaporator, in order to prevent freezing and equipped with its own thermo-
stat.
RD Shut-offvalveondischargeside:They are used to isolate compressors during service operations.
RF Powerfactorcorrectionsystemcos≥0,9:Electrical device made of suitable condensers for compressors rephasing, ensuring a cos
value ≥0,9, so to reduce the reactive power absorption from the electrical network.
RH Shut-offvalveonsuctionside:They are used to isolate compressors during service operations.
RL Compressorsoverloadrelays:Electromechanical protection devices against compressors overload.
RM Condensingcoilwithpre-paintedns:Supercial treatment of the condensing coils with epoxy coating (available for RAH Ka range)
RP Partialheatrecovery:(about 20%) of condensing heat through a refrigerant/water plate exchanger (desuperheater) always in series to the
compressors. It is used when you want to partially recover condensing heat for producing hot sanitary water.
RR Copper/coppercondensingcoil:Special execution of the condensing coils with copper pipe and ns.
RT Totalheatrecovery:(100%) of condensing heat by refrigerant/water heat exchanger in alternative and in parallel to the condensing air section. It
is used when you want to completely recover condensing heat for producing sanitary water or for heating applications (available for RAH Ka range).
V Voltmeter: Electrical device measuring the electrical voltage of the unit power supply.
VB BrineVersion:Unit suitable for working with evaporator outlet water temperatures lower than 0°C. A 20 mm evaporator insulation will be provided.
VS Solenoidvalve:Electromagnetic solenoid valve on each cooling circuit to cut off the liquid line at compressors stop.
