EcoSmart - Refresh Cycle

If an HVAC system supports active dehumidification, EcoSmartTM thermostats can be outfitted with a Relative Humidity sensor that will engage in dehumidification until humidity has fallen below the RH% by a programmable increment. However, when an HVAC does not have an active dehumidification stage, EcoSmart thermostats can employ an effective passive dehumidification strategy called the “Refresh Cycle.” By adjusting both the length and the frequency of the refresh cycle drives, the Refresh Cycle can keep relative humidity at manageable levels during periods of unoccupancy. It can be an effective dehumidification strategy for systems that do not have any provisions for active dehumidification--such as reheat elements.
