American Standard ACONT402AN32DAA Non-Programmable Thermostat

The American Standard ACONT402AN32DAA Non-Programmable Thermostat is a 24-volt, wall‑mount thermostat designed for 3H/2C operation, with support for conventional furnaces and heat‑pump/dual‑fuel configurations. This non‑programmable model handles up to three heat stages and two cooling stages and is compatible with standard 24 VAC HVAC systems used by American Standard/Trane equipment. It features a backlit LCD display and keypad for straightforward manual control, and ships with factory default settings that can be restored via the control configuration menu. The operating range spans approximately 32°F to 110°F with 5–90% relative humidity tolerance, making it suitable for typical indoor environments. Intended for indoor installation, the ACONT402AN32DAA serves as a direct replacement for older 24V thermostats in homes using gas or electric furnaces or heat pumps, including dual‑fuel setups.
