Intermatic 178gr10k-1 Additional Sensor Assembly

Product Description

The INTERMATIC 178gr10k-1 is an additional sensor assembly designed for multiple evaporator applications in refrigeration and HVAC control systems. The kit includes a 6-inch input wire, a 10-foot thermistor sensor, a 3/8-inch tube-clip, wire nuts, and a cover plate, giving technicians everything needed to expand sensor coverage across multiple evaporator coils served by a single controller. This assembly is installed by licensed HVAC-R technicians and is suited for commercial refrigeration cases, walk-in cooler systems, and multi-evaporator setups where individual coil temperature sensing is required.

This sensor assembly is intended for installations where a primary Intermatic controller monitors more than one evaporator. The thermistor sensor mounts directly to the evaporator tubing via the included tube-clip, while the input wire connects back to the controller terminal block. Typical applications include multi-circuit refrigeration systems in grocery, foodservice, and light commercial environments where accurate per-coil temperature data is essential for defrost management and energy efficiency.

Key Features

• 6-inch input wire for clean routing to the controller terminal block
• 10-foot thermistor sensor provides reach across larger evaporator assemblies
• 3/8-inch tube-clip allows direct mounting to evaporator tubing without additional hardware
• Includes wire nuts and cover plate for a complete, code-ready installation
• Designed to expand sensing capability in multiple evaporator control configurations

Compatibility

Designed as an OEM-style additional sensor assembly for Intermatic multi-evaporator control systems where supplemental thermistor sensing is required.

Installation Notes

Installation should be performed by a qualified HVAC-R technician. Disconnect power to the controller and any associated refrigeration equipment before beginning sensor installation or wiring work. Secure the thermistor sensor to the evaporator tubing using the included tube-clip, ensuring firm contact for accurate temperature readings. Follow all applicable local codes and the controller manufacturer wiring guidelines when terminating the input wire at the controller terminal block.
