About TrueIAQ® 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.
Operation TrueIAQ® can be used to control the humidity levels in your home, and control fresh air intake in accordance to industry recommendations (ASHRAE 62.2). Comfort Settings: Feedback on your indoor IAQ conditions. 1 Outdoor Conditions : Actual outdoor temperature and humidity. Indoor Conditions: Actual indoor temperature and humidity. 68 40 76 55 In Programmable Clock: Displays time and allows IAQ equipment programming based on time.
Display screen reference Wet: Indoor humidity levels are above 60% RH. Dry: Indoor humidity levels are below 20% relative humidity (RH.) 68 40 76 55 In % Out De Humidify: If “Humidify” is displayed, the control is calling for more humidity. If “DeHumidify” is displayed, the control is calling for humidity removal. % 12 : 15 PM Window Frost: The control is protecting your home against too much humidity based on outdoor conditions.
Changing humidifier settings Note: These items will appear only if a humidifier is installed on your system. 1. Set humidifier by pressing UP/DOWN arrows. 35 Tables below are recommended initial humidity settings based on outdoor temperature. If window frost setting (see next page) is not being used, the humidity setting should be adjusted manually when outdoor conditions change. Outdoor Temp.

Installation CAUTION: ELECTRICAL HAZARD. Can cause electrical shock or equipment damage. Disconnect power before beginning installation. 1. Turn system power off. 2. Choose a location. TrueIAQ® can be mounted to a wall or directly to the return duct. ELECTRON IC AIR CLEANER M24787 69-2072—05 69-2072_C.
Installation 3. Loosen the cover screw. 4. Separate the front housing from the base. M24814 5. For wall mounting, run wires through the back hole to the terminals. Wire size for all connectors: 2 x 18 AWG to 1 X 22 AWG. Install the mounting plate using two screws. M24818 A 6. For duct mounting, (A) snap out side wall clip and attach as shown. Run wires through the side wall hole, under the clip, to the terminals. (B) Snap in sensor cap. 7.
