- Humid (like in southern & eastern US)
- HAVEN Monitor
- HAVEN Controller x2
- Ventilating dehumidifier with 24VAC input (like the Santa Fe Ultra Aire 98H or 120H, or AprilAire e100V)
- Motorized damper with 24VAC input, in an outdoor air duct
- Air handler with 24VAC input
What does it do
- Monitors indoor tVOC levels to know when you need a burst of fresh air
- Opens damper & optionally activates ventilating dehumidifier's compressor to dehumidify the humid outdoor air we're bringing in
- Closes the damper if outdoor AQI (standardized rating based on a combination of particles and chemicals) reaches a certain unhealthy limit
- Monitors indoor relative humidity and temperature to calculate dew point to see if it needs moisture removal
- Toggles on the ventilating dehumidifier's compressor to dehumidify the indoor air
- The HAVEN Monitor in this scenario is installed in the indoor return duct of the air handler. HAVEN configures a circulation schedule in order to toggle the air handler fan on/off regularly throughout the day to take regular samples and filter the air.
- Monitors PM2.5 levels to determine when further filtration is needed
- Keeps the air handler running and activates the ventilating dehumidifier's fan (separate from the compressor which dehumidifies the air)
How does it all fit together?

*1 — What's dew point?
It's a calculation that uses indoor relative humidity and temperature to determine when dew will form on surfaces. This can lead to moisture problems! Dew point is a precise parameter to use for humidity control, because the amount of water the air can hold depends on its temperature! Without taking temperature into consideration, we're controlling based on a relative parameter.
