-
For a CHWP, the designers should evaluate the flow control at the cooling/heating coil in the air-handling units and should consider a potential retrofit from 3-way to 2-way valve and/or pressure differential sensors and controls that may be needed to adequately complete the meausure.
-
In all cases, measure installation must meet all applicable regulations including but not limited to the current California Building Energy Efficiency Standards (Title 24) and the National Electrical Code®.
