*** 1 – “HEALTHCARE BEDS” Represents the maximum recommended number of healthcare facility beds for a single DHW zone. The Domestic Hot Water Return (DHWR) is always the determining factor. If the DHWR exceeds the recommended size for the number of beds, the CSI system will be sized for the next model to ensure proper water flow. DHWR always overrides the number of beds, rooms, or occupants in determining the appropriate model.
*** 2 – “HOTEL ROOMS” Represents the maximum recommended number of hotel rooms for a single DHW zone. The Domestic Hot Water Return (DHWR) is always the determining factor. If the DHWR exceeds the recommended size for the number of rooms, the CSI system will be sized for the next model to ensure proper water flow. DHWR always overrides the number of rooms in determining the appropriate model..
*** 3- “CONDO / BLDG OCCUPANTS” Represents the maximum recommended number of occupants for a residential building. The Domestic Hot Water Return (DHWR) is always the determining factor. If the DHWR exceeds the recommended size for the number of occupants, the CSI system will be sized for the next model to ensure proper water flow. DHWR always overrides the number of occupants in determining the appropriate model..
