PRINCIPLE OF OPERATION NORMAL OPERATION: During normal operation the bypass is closed (both handles are positioned parallel with water flow), and water will flow through the strainer, into the FCU and return through the PICV valve. During this operation the PICV will balance the flow from closed valve to de- sign flow depending on actual requirements and cor- responding actuator position. BYPASS OPERATION: Option 1. During bypass operation the FCU is isolated from the system. The FCU may, after draining, easily be ser- viced while the main system is running unaffectedly. It will also be in bypass operation that the main system is flushed without compromising FCU components. Option 2. In addition, complete isolation of the FCU is possible providing closed bypass and isolated flow- and return- side.
