Honeywell C7189U1005/U – Remote Indoor Temperature Sensor for HVAC Zoning and Monitoring

The Honeywell C7189U1005/U is a remote indoor temperature sensor designed for use with compatible Honeywell thermostats. It provides accurate ambient temperature readings from alternate locations within a controlled space, supporting consistent HVAC system performance across varying conditions. Common applications include zoning systems and installations where the thermostat location may not reflect actual room temperature.

Product Overview

This sensor is typically mounted on an interior wall and connected directly to the thermostat via low-voltage wiring. It is factory-calibrated and does not require field adjustment. The compact enclosure includes integrated mounting tabs for standard wall installation using the supplied hardware.

Key Features

• Remote Temperature Input: Allows thermostats to receive temperature data from a remote room or zone
• Factory-Calibrated Sensor: Eliminates the need for manual calibration during installation
• Low-Profile Housing: Blends into the environment and installs cleanly with minimal footprint
• High Humidity Tolerance: Operates effectively in non-condensing environments up to 95% RH
• Broad Compatibility: Works with a wide range of Honeywell thermostat models supporting remote sensors

Technical Specifications

• Model: C7189U1005/U
• Temperature Range: 45°F to 88°F (7°C to 31°C)
• Humidity Range: 5% to 95% RH (non-condensing)
• Dimensions: 2.25" H x 1.5" W x 0.75" D
• Mounting Method: Wall-mounted using screws and anchors (included)

Installation Notes

Sensor should be installed in an area that represents average room conditions and is free from direct airflow, sunlight, or heat sources. Use low-voltage thermostat wire for connection back to the thermostat terminal block. Wiring must be consistent with manufacturer specifications for remote sensor integration. Ensure secure wall mounting for reliable long-term performance.

Contractor Considerations

• Verify thermostat compatibility before sensor deployment
• Install at a standard interior height for optimal sensing accuracy (typically 5 feet from floor)
• Avoid mounting near HVAC outlets, windows, or electronics that may influence readings
• No software configuration required when installed per Honeywell guidelines

Summary

The Honeywell C7189U1005/U is a dependable indoor sensor designed to extend temperature sensing capabilities for thermostats in residential or light commercial HVAC systems. It supports zoning accuracy, improves system control, and simplifies temperature management in applications where remote measurement is required.
