Builders always wanted to sell indoor air quality (IAQ) systems, but in the past, adding a humidifier, dehumidifier, and ventilator to an HVAC system meant the installer had to hang four devices and run more than a dozen wires through the walls. Home buyers also tended not to add such devices after they moved in because it meant tearing up the walls.
Nowadays Honeywell's VisionPro IAQ lets builders hang all the additional IAQ gear near the HVAC system and run the wires to an equipment interface module that sits nearby. The builder can then run a series of three wires, one each for power, ground, and communication, from the module to the thermostat. By centralizing the wiring in the equipment interface module, builders are now able to offer home buyers one wall device for all four functions: thermostat, humidifier, dehumidifier, and ventilator.
“The VisionPro makes it easier for builders to sell IAQ as an upgrade,” says Reg Zeller, product manager for programmable thermostats. “With the VisionPro, everything is hardwired during construction, and the builder can have the installer come in and add on a humidifier without ripping up the walls.”
Zeller says VisionPro will cost home buyers from $400 to $600. For an additional $400 to $600, buyers can opt for a telephone access module, which lets them change the settings of the IAQ system or set up alerts using a telephone. A Web-based capability in which homeowners can manage the IAQ system over the Internet will be available later this year. (www.honeywell.com)
