Figure 9 – H1008 Automatic Humidity Control Hardware Closed Loop Run
Figure 9 is the identical case, with the actual H1008 hardware and software in control of
the simulated humidifier. The results are very similar, with relatively light cycling of the
humidifier during the colder periods, and heavier cycling of the humidifier during the
warmer periods of the day. Again, during the entire period the dewpoint tracked just
below the window temperature, maintaining moisture free windows.
