Venstar acc0401 Wired Indoor Temperature Sensor

Product Description

The VENSTAR acc0401 is a wired indoor temperature sensor designed to provide accurate ambient readings for compatible VENSTAR thermostat systems. The sensor operates across a wide temperature range of -40 to 125 degrees F, making it suitable for demanding residential and light commercial HVAC applications. Its compact housing measures 1.4 inches wide, 0.63 inches deep, and 1.8 inches tall, allowing straightforward installation in tight spaces. Licensed HVAC technicians and skilled installers typically deploy this sensor as a remote sensing point, enabling thermostats to monitor temperatures in zones away from the main thermostat location.

This sensor is intended for indoor use and is compatible with VENSTAR thermostats in both indoor and outdoor thermostat applications. It is used with specific VENSTAR thermostat models including T1100FS, T1700, T1800, T1900, T2700, T2800, T2900, T2300FS, and TSTATEZ units. It is well suited for residential HVAC zoning setups or commercial installations where remote temperature monitoring is required to improve system efficiency and comfort control.
