The TrueIAQ® monitors and automatically adjusts operation of your whole-house humidifier, dehumidifier, ventilator, or bath fan.

Maintaining proper indoor humidity minimizes the potential for unhealthy airborne pollutants 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 operation. If you have both a humidifier and dehumidifier installed, the TrueIAQ can automatically 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 efficiency, 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 programmed to deliver ventilation during set times of the day or night.

If both humidifier (hum) and dehumidifier (dehum) are installed:

Dehum setpoint can only be equal to or higher than Hum setpoint. If equal, equipment changeover will be at least 5% higher (dehum) or lower (hum).

If not equal, changeover occurs at setpoint plus 2% RH (control’s deadband).
