Electronic Temperature Defrost Control Relay Pack (Replacement Control Relay Pack) Johnson Controls

Description

The MR series temperature controls are designed for use with hot gas or electric heat defrost in both refrigeration and freezer units. Either time or temperature based defrost termination may be selected. The MR series incorporates control functions such as compressor control, defrost management, fan management, and alarm management.

Features


• single package provides the functionality of multiple components at a cost-effective price


• mounting flexibility allows the control and relay pack to be mounted together or separately, facilitating multiple configurations


• easily readable temperature display can show either evaporator or process temperature at the touch of a button


• accurate, interchangeable temperature sensor provides reliable control performance with up to 300 ft. of wiring (an offset is provided for longer wiring)


• heavy-duty relays allow direct control of compressors, fans, defrost heaters, and alarms


• alarm management functions provide both local alarm codes and a relay closure that can be used to trigger a remote alarm or a dial-out modem

Applications

These relay pack mounted controls provide direct control of compressors up to 2 hp, electric heater loads of up to 20 amperes, and evaporator fan loads of up to 3/4 hp. The need for separate relays is eliminated in these applications.

In addition, the MR4PMUHV controls combine the functionality of an electromechanical thermostat, mechanical clock, defrost termination device, and temperature readout device with the accuracy of electronic technology.
