SZ-7534 Temperature Controller Subzero

The SZ-7534 controller is engineered for cold room applications requiring reliable and accurate temperature management. It operates within a wide temperature range from -50.0°C to +50.0°C with 0.1°C resolution, ensuring precise control for refrigeration systems.

Equipped with two NTC probes, the controller monitors both the cold room temperature and evaporator coil temperature. It supports relay outputs for compressor, light, heater, and evaporator fan, enabling full system coordination. Automatic and manual defrost options help prevent ice buildup and maintain operational efficiency.

The unit features compressor protection through High Pressure, Low Pressure, and Oil Safety Switch trip safeguards. A built-in audible alarm alerts users to system faults or temperature deviations, while the 7-segment LED display ensures clear and easy monitoring.
