Remote access to thermostats gives users the ability to monitor HVAC equipment and make adjustments when they are away from the home or building. This can be ideal for vacation homes, landlords, or simply people who want the ability to change heating and cooling settings before arriving home.
Honeywell’s RedLINK Internet Gateway works with any of their RedLINK-enabled thermostats. The gateway wires to an internet router and communicates wirelessly with thermostats using RedLINK signals (which tend to be as reliable as wires and have been successfully tested in homes up to 10,000 square feet). The Internet Gateway allows users to control thermostats online with Honeywell’s Total Comfort Connect website and apps, which require no additional usage fees. These resources give authorized users the ability to modify system (heat, cool, off, etc.) and temperature settings for multiple zones and buildings, while allowing them to provide up to six email-alert contacts. Each Internet Gateway can handle up to four thermostats, but multiple gateways can be accessed from the same online account. RedLINK thermostats work with several other wireless accessories including indoor and outdoor sensors, the Portable Comfort Control, and (on IAQ models) humidification equipment. For line-voltage applications, Honeywell offers the RedLINK-ready EConnect system.
Honeywell also offers several Wi-Fi thermostats, including select VisionPRO and FocusPRO models. Select Wi-Fi 9000 thermostats also allow voice-command adjustments to temperature settings. These Wi-Fi thermostats do not require an Internet Gateway. Instead, they connect to a building’s available Wi-Fi network. Honeywell’s Wi-Fi-enabled thermostats are accessible from the same Total Comfort Connect website and apps. They can serve as a more affordable way to gain remote access and can frequently be wired in place of existing low-voltage thermostats (note that a common wire is needed for operation).
