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 previously configured 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.
