|Primary flow temperature|
|Primary return temperature|
70°C Primary Flow = 27.9°C; 60°C Primary Flow = 29°C (Volume-Weighted Average Return Temperatures (VWART))
<50 kPa (primary side), <10 kPa (heating)
|Heating supply temperature|
|Hot water supply temperature|
Fully insulated EPP casing
Electronically controlled. The HIU controller shall utilize the secondary side DHW and heating temperatures to control Pressure Independent Control Valves (PICVs) located on the primary side of both plate heat exchangers to maintain the temperature. A keep warm function maintains a primary flow temperature at the unit
