A room humidistat initiates the lowering of the humidity of the conditioned supply air to a space, while the actual process is accomplished by what means?

Correct Answer: Option A — lowering the cooling coil temperature and raising the reheater temperature

A room humidistat lowers space humidity by lowering the cooling coil temperature to extract more moisture through condensation, while simultaneously raising the reheater temperature to prevent over-cooling the conditioned space.
