Venstar t3700 Programmable Thermostat 2 Heat 1 Cool

Product Description

The VENSTAR t3700 is a multi-stage, digital programmable thermostat with built-in Wi-Fi designed for residential HVAC systems. It supports 2-heat/1-cool staging and offers flexible scheduling with 7-day, 5-2 day, or 1-day programming options. The t3700 measures 4.6 inches wide, 1.1 inches deep, and 5.2 inches tall, making it a compact fit for standard wall installations. Built-in Wi-Fi enables remote access and control without a separate smart-home bridge or add-on module. Licensed HVAC technicians and knowledgeable homeowners install this unit as a direct upgrade on forced-air gas, electric, and heat pump systems where multi-stage control is required.

The t3700 is suited for residential applications involving gas furnaces, electric air handlers, and single-zone heat pump systems. Its multi-stage logic accommodates two-stage heating equipment common in mid-efficiency and high-efficiency gas furnaces as well as dual-stage heat pumps. The programmable schedule supports households with varied weekly routines, allowing technicians to configure setpoint schedules that match occupancy patterns and reduce unnecessary run time. This thermostat is a practical replacement or new-installation choice on any residential system calling for 2-heat/1-cool wiring.
