Two-way valve
For some sizes, the manufacturer supplies a three-way modulating valve, with way "B" closed or to be clo-
sed with a blind flange, to be used as two-way valve.
If the signal for controlling the valve is used, connect the servo control as shown in the wiring diagram.
As an alternative to the modulating valve, it is possible to use a pressure switch valve for each refrigerant circuit that will
ensure an average condensing temperature of at least 40°C.
