AKO-D14423 is a 4 relay refrigeration control with 3 sensor inputs (1 supplied). Relay outputs for compressor 6(4)A, fan 6(4)A , defrost 6(4) and an auxillary output 6(4)A which is programmable as Defrost, Alarm or Light.Defrosts programmable by controlling compressor, resistances (or cycle reversal) and fans. A optional probe allows defrosting by temperature and a 3rd one (also optional) can control 2nd evaporator driven by the same compressor . Programmable digital inputs such as door switch, external alarm, remote defrost, energy saving or continuous cycle. Configuration wizard depending on application (8 configurations).The AKO-14423-RC model has integrated RS-485 communication.An ntc thermistor sensor is supplied with a range of-50.0/99.9 Deg.C or -50.0/150 Deg.C with a Ptc sensor.Standard 34 x 76mm front panel mounting with IP65 gasket. It's bright display makes for easy reading.With 0.1 Degrees resolution, adjustable hysterisis from 0.2 Deg. and scale in C or F, the result is a versatile accurate thermostat.

For 1 relay defrost control please see AKO-D14123. (25.01.310)

The AKO-D14423 is AKO's new alternative to the now discontinued AKO-14423.
