1.Aluminum housing for DIN rail mounting;
2.Low superheat alarm

     EC3-X33 is a stand-alone universal superheat controller for air conditioning, refrigeration and industrial applications such as chillers, industrial process cooling, rooftops, heat pumps, package unit, close control, cold room, food process and air driers.  The optional ECD-002 Display/Kaypad Unit is necessary for setup but not for operation of the controllers. ECD-002 can be connected or disconnected to EC3-X33 at any time.

Features of EC3-X33:

1.EC3-X33 Superheat control in conjunction with ALCO Controls stepper motor driven Electrical Control Valves (EX4 … EX8)

2.Limitation of evaporating pressure (MOP)

3.Low superheat alarm

4.Feed through of 4…20mA signal from evaporator pressure sensor to analogue output. This may also be connected to pressure input of any other controller to avoid need for multiple pressure sensors

5.Monitoring of sensors and sensor wiring and detection of sensor and wiring failures

6.Intelligent alarm management in order to protect the compressor i.e. fail safe operation

7.Integral rechargeable battery to close Electrical Control Valve in case of power loss

8.Electrical connection via plug-in type screw terminals;

9.Aluminum housing for DIN rail mounting

Features of ECD-002:

1.2½ digit LED display with automatic decimal point

2.Indicator LEDs for valve opening/closing, external demand and alarm

3.Connection to EC3 Series via ECC-Nxx or standard CAT5 patch cord with RJ45 connectors
