The IC 974 LX NTC 12Vac controller by Eliwell is designed for normal and low-temperature refrigeration systems. It features two PTC thermostatic probe inputs (NTC selectable via parameters) and two relay outputs for compressor and defrost management. The defrost cycle can be terminated based on a set time or by reaching a specific temperature detected by a probe placed on the evaporator. The controller is designed for panel mounting with standard 32x74 mm dimensions and operates on a 12 V AC/DC power supply.
