Installation and Operating Instructions
UNIVERSAL–XR60CX
1. GENERAL DESCRIPTION
Model Universal-XR is a 71x29 mm format microprocessor based controller, suitable for applications on high, medium or
low temperature refrigeration units. It is provided with three relay outputs to control compressor, defrost - which can be both
electrical or hot gas - and evaporator fans. It can work with PTC or NTC probes. Where defrost is being terminated by time,
it can operate with just one thermostat probe. Where defrost is being terminated by temperature, it has an input for an
evaporator probe(s).
The Universal-XR is equipped with a flashing visual alarm and buzzer.
Each instrument is fully configurable through special parameters that can be easily programmed through the keypad.
