There are many control platforms with abundant input/output points and programmed operating sequences. However, there is wide variation in the quality and support associated with the control sequences embedded in these controllers. Pre-programmed sequences that have been tested and proven offer the most reliable equipment operation. Specifically, the availability of a flexible, fine-tuned dehumidification sequence is critical to creating and maintaining proper space conditions. HVAC equipment is often controlled to maintain only the desired space temperature, which when coupled with high humidity levels, does not create a comfortable environment. Instead, look for a dehumidification sequence that can consistently deliver cool, dry air to the space to maintain both space temperature and relative humidity set points.
Several criteria can trigger dehumidification mode. Determining the correct trigger depends on the application and can be the difference between maintaining consistent space conditions (proactive) versus playing catch up to attain the desired space conditions (reactive).
