| REGULATOR WITH ELECTRONIC EXPANSION VALVE |
||||
|
Electronic regulator for counters/cold rooms control with electronic expansion valve. Configurable with remote display, integrated display and echo for temperature repetition (optional), it integrates the counter functions and the control for the electronic expansion valve. |
|
|
| Applications • Refrigerated counters and cold rooms. Main characteristics • Control of electronic expansion valve ON/OFF with 230 VAC coil. • Analogic input for pressure and temperature probes. • 0-10 V analogic output for fans management with speed variator. • Integrated or remote console of control (in case of integrated console, there is an optional echo display repeater of temperature). • Different temperature set point for night and day. • Serial RS485 connection with TeleNET or Modbus protocol selectable by parameter. • Output for compressor (or evaporator solenoid) fans, defrost (real time clock), light, alarm or AUX. • Three configurable digital input. • Analogic inputs for temperature of supply and return air (with virtual temperature probe), end defrost. • Suction temperature probe and evaporation pressure probe for control of evaporator overheat. • Master slave connection. • IP65 remote display protection. • Easy startup with 4 settings built in for the different application. |
