15.17 Dew point temperature monitoring
As a supplement to the condensation monitor, the primary chilled water
temperature is compared against the present dew point temperature in the
room. The chilled beam valve is closed if the chilled water temperature drops
below the dew point temperature at a configurable difference. The chilled beam
valve is once again released if the chilled water temperature exceeds the dew
point temperature, with consideration of a configurable difference and a dead
zone.
