Description

This item is DISCONTINUED/ END-OF-LIFE (EOL). It has been replaced with T3950-IAQ (please contact us if this recommended replacement is not quite what you need).

Manufacturer Part Number: T3900

Venstar T3900 Voyager thermostat comes with a large, backlit display that gives them the ability to see if the thermostat is calling for heating or cooling from across the room. Set the deadband for 1 degree and if the indoor temperature is not exactly as set, Voyager begins to actively cool or heat. For those homeowners who choose to not run a program but still want to save on operating costs, they simply press the "Away" button on their Smartphone when leaving home, and then the "Home" button before returning. With the optional ACC-VWF2 WiFi module, homeowners can even change the indoor temperature using their Smartphones.

The Daikin D4273 is identical to the Venstar T3900 (just rebranded/relabeled).

  • 7-day, 5+2 day or 1-day programming; Gas/Electric or heat pump - Multi-stage
  • Venstar Wi-Fi module (ACC-VWF2) is sold separately
