EXD-HP1/2 Stand-alone Superheat/Economizer Controller
EXD-HP1/2 are stand-alone universal superheat and or economizer controllers for heat pumps, heating units, air conditioning and precision cooling such as telecom and shelter applications.
- Self adapting superheat/economizer control in conjunction with EMERSON stepper motor driven electronic expansion Valves EXM/EXL
- Dischargehot gastemperature controlbyliquid/vaporinjectionto compressor
- EXD-HP1: Controller with one EXV output
- EXD-HP2: Controller with two independent EXV outputs
- Controllers as slave with Modbus (RTU) communication capability. All data (read/write) accessible by any third party controller having modbus communication (RTU)
- Upload/download key (accessory) for transmission of parameter settings among controllers with the same setting
- Released for applications using A2L and A3 refrigerants
- Low pressure switch and freeze protection function
- Manual positioning of valve(s)
- Limitation of evaporating pressure (MOP)
- Low/high superheat alarm
- Monitoringofsensorsandsensor wiring/detection ofsensor andwiringfailures
- Integrated display (3-digit LEDs) and keyboard
- Electrical connection viaplug-intype screw terminals(included withcontroller)
- DIN rail mounting housing
