Product Name ETC-974 Digital Temperature Controller – 230V Refrigerator Defrost Heating Thermoregulator with Dual NTC Se

Maintain dependable temperature control and keep refrigeration systems operating within your preferred range. This versatile digital temperature controller uses dual NTC sensor inputs to support temperature monitoring and refrigeration, defrost, and fan control. Its clear display offers selectable whole-number or decimal resolution for convenient temperature readings. Designed as a refrigerator temperature controller, it supports a broad measuring range and multiple relay-controlled functions. Compact dimensions also make it practical for integration into compatible refrigeration and temperature-control systems.

Key Features
• Dual NTC sensor inputs provide temperature monitoring for compatible refrigeration control applications.
• Refrigeration, defrost, and fan relay controls support multiple temperature-management functions from one unit.
• Selectable 1°C or 0.1°C display resolution provides flexible temperature viewing based on your setup.
• Wide temperature measurement capability supports demanding refrigeration and thermal-control applications.

Why Choose Our ETC-974 Digital Temperature Controller?
Compared with basic single-function controllers, this unit combines refrigeration, defrost, and fan control with two NTC sensor inputs in one compact device. Its broad measurement capability, selectable display resolution, and dedicated relay outputs provide greater flexibility for compatible refrigeration systems.

Perfect For
Ideal for technicians, refrigeration professionals, equipment installers, maintenance applications, and compatible temperature-controlled systems. It is suitable for refrigerators and other setups requiring coordinated refrigeration, defrost, fan, and temperature monitoring functions.
