Operation
Digital Temperature Control:
The Tempra 24 Plus features a digital display and controls for setting your desired hot water temperature. The unit will then maintain this temperature consistently.
Advanced Flow Control:
This exclusive technology actively monitors water demand. If the demand for hot water exceeds the unit's heating capacity, the Advanced Flow Control will automatically and slightly reduce the water flow rate to ensure the hot water temperature remains at your set point, preventing sudden cold water surges.
