About TrueIAQ

The TrueIAQ monitors and automatically adjusts operation of your whole-house humid-

ifier, dehumidifier, ventilator, or bath fan.

Maintaining proper indoor humidity minimizes the potential for unhealthy airborne pol-

lutants to grow. Having too little humidity can leave you vulnerable to infections and

uncomfortable dry skin. Too much humidity creates ideal breeding grounds for mold,

mildew and dust mites. Humidified air also feels warmer in the winter, and dry air feels

cooler in the summer.

TrueIAQ can adjust humidity with or without dependency on HVAC equipment opera-

tion. If you have both a humidifier and dehumidifier installed, the TrueIAQ can automati-

cally change over to the appropriate equipment based on your comfort settings and the

changing outdoor conditions.

TrueIAQ can also deliver fresh air with or without dependency on HVAC equipment

operation. Today’s building codes require homes to be built more tightly for energy effi-

ciency, but that tightness can also trap indoor air pollutants, such as cooking odors,

cleaning agents, radon, and carbon dioxide/monoxide. TrueIAQ provides cost-effective

ventilation in accordance to industry standards. In addition, the TrueIAQ can be pro-

grammed to deliver ventilation during set times of the day or night.

Mounting the outdoor sensor

. Do not mount on the south side of the house or in direct exposure to sunlight.

. Keep at least 4 feet away from exhaust

vents.

. If in an air intake, place 1 foot closer to

outside wall.

. Place at least 6 inches higher than

possible snow buildup.

. Do not route sensor wire near high

voltage wires.

Note: The sensor can be extended using

8-gauge wire.
