The Robertshaw RS10420T is a Wi-Fi-enabled, 7-day programmable touchscreen thermostat designed to provide precise temperature control for both residential and commercial HVAC systems.  It supports up to 4 stages of heating and 2 stages of cooling, making it suitable for complex multi-stage systems, including heat pumps with or without auxiliary or emergency heat.  The thermostat operates on 24V AC power and requires a common wire (C-wire) for installation.  Its sleek design features a large 8.8-square-inch blue backlit touchscreen display, offering clear visibility and intuitive navigation.

This thermostat offers 7-day programming with 5-1-1 scheduling, allowing users to set different temperature settings for weekdays, Saturdays, and Sundays.  It includes intuitive programming icons for wake, leave, return, and sleep periods, facilitating easy customization to match daily routines.  The RS10420T is compatible with Alexa and the Robertshaw app for iOS and Android, enabling remote access and control via smartphones or voice commands.  Additional features include auto changeover, dual-fuel compatibility, filter change reminders, compressor delay protection to prevent short cycling, keypad lockout, and adjustable temperature differential (swing) for energy optimization and system longevity.

Installation is streamlined with large terminal blocks and a universal sub-base, accommodating various system configurations.  The thermostat is compatible with gas, electric, or oil systems and supports millivolt applications.  Its temperature control range spans from 41°F to 90°F (5°C to 32°C), with a display accuracy of ±1°F at 68°F (±1°C at 20°C).  This replaces the Braeburn 6300 Programmable Hybrid Thermostat.
