Operating Manual Setting the controls The colder it is outside, the less humidity can be retained by the air. Initially setting your humidistat to ideal comfort levels will help your TrueSTEAM deliver optimal humidification. The table below provides suggested control settings based on outdoor conditions. You may experience that your home needs humidity levels to be slightly higher or lower than the suggested levels given in the table, in order to prevent window condensation or dryness. This is because your home is unique in size, shape, building tightness, and age. These variables play an active role in how your indoor humidity fluctuates. Use the table as a starting point, but adjust according to your comfort and observations of condensation. Outdoor Temperature -20°F (-29°C) -10°F (-23°C) 0°F (-18°C) 10°F (-12°C) 20°F (-7°C) >20°F (-1°C) Recommended RH % Setting 15% 20% 25% 30% 35% 40% With automatic controls like TrueIAQ and VisionPRO IAQ, you need only calibrate this setting once. The automatic feature will adjust by itself as outdoor conditions change, based on your initial settings. After setting your auto control to the desired RH% level, check for condensation or frost forming on windows on the first cold day. If present, adjust your frost settings on the control (see control owner's manual if needed). The Window Frost Protection feature protects your home by limiting humidity output based on outdoor conditions (for example, on colder days, your home can hold less humidity). LESS HUMIDITY LOOSE HOME/SINGLE-PANE WINDOWS 1 2 3 4 5 MORE HUMIDITY TIGHT HOME/TRIPLE-PANE WINDOWS 6 7 8 9 M24830 Frost Settings should be lowered by one value each morning that you see frost or condensation on windows. Allow 24 hours for the adjustment to take affect. Once you have this set to a comfortable level without condensation forming, you will not need to adjust this again. You can adjust your humidity settings without worrying about condensation. With Manual Humidity Controls-such as the H8908-you will need to adjust your RH% settings each time the outdoor conditions change (more humidity with warmer outdoor conditions, lower humidity with colder conditions). These controls provide accurate operation, but require more hands on adjustment. These controls are a good choice for homeowners who desire continuous interaction with humidity settings. 69-2035EFS-05
