Скачать или смотреть EQ Valve Module – EQVM

The Parker Sporlan EQ Valve Module is a controller designed for responsive superheat control in HVAC systems. Up to 2 coils (evaporators) can be measured and controlled. The controller will use pressure/temperature sensors to measure each coil’s superheat and position up to 2 electronic expansion valves. The controller can be configured to control two coils that share a tempera- ture and/or pressure (common suction or heat pump designs) or have individual suction lines (main compres- sor plus supplemental designs). The controller includes status LEDs and RS-485 network port connectivity to allow setup and readout of values.
