Built for residential HVAC control

The Venstar Voyager T3700 is a WiFi thermostat designed for homeowners who want programmable or non-programmable climate management. It supports two heating stages and one cooling stage with auto-changeover for gas-electric or heat pump systems. The large scrolling display simplifies setup and daily adjustments.

Sustained scheduling and remote access

Seven-day, 5+2 day or one-day programming lets the thermostat maintain consistent comfort over weeks rather than a single burst of changes. Skyport connectivity provides free smartphone and computer control without monthly fees. Over 10 configurable alerts track heating and cooling run-time daily and monthly while flagging service needs.

Quiet low-voltage operation

The unit runs on standard HVAC control voltage so it adds no audible fan noise and draws minimal power during normal use. Adjustable backlight intensity keeps the display readable without glare. Dealer contact information and custom messages can appear on screen for quick reference.
