Cooling and heating capacity savings are a function of internal loads, thermostat and humidistat settings, and internal sensible and latent loads, rather than on outdoor air psychrometric conditions.
An option is to have the bathroom fans set on a humidistat so they turn on as the relative humidity reaches the set level, but that requires an air supply of equal capacity, since tight houses may not have enough cracks and crevices to supply it.
If the humidistat is located on the surgery room walls, which it generally is, there will be a sharp differential between the actual humidity level at the patient and the humidity level measured at the humidistat.
Low-wattage extractor fans could be [euro]tted in kitchens and bathrooms with humidistat controls which will turn on when the air becomes humid.
When humidistat control was required, setpoints of 50% and 60% rh were used.
In addition to the thermostat, a humidistat controls the relative humidity of the core zone, providing humidification (by means of an electric steam humidifier placed in the main air loop) when relative humidity falls below 45% and dehumidification (by means of the cooling coil placed on the main air loop) when the relative humidity increases above 60%.
Many of the newer models come with a digital humidistat and automatic outdoor temperature compensation (such as the Honeywell No.
New plumbing, new electric, a Vantage lighting system, Mitsubishi central air, humidifier regulated by humidistat, and new carbon monoxide and smoke/heat detectors.
The problem was exacerbated by fitting an extractor fan controlled by the lights rather than a humidistat.
