- Use the up and down arrows on the control panel to adjust the desired hot water temperature.
- A green 'In Use' light indicates when hot water is being drawn and the unit is actively heating.
Circ-Logic Technology:
This feature allows for customized hot water recirculation. When paired with an external pump, you can set recirculation patterns to align with your household's hot water usage habits, minimizing wait times for hot water at the tap.
Understanding Flow Rate:
The actual hot water flow rate (GPM) can vary based on the incoming groundwater temperature. Colder incoming water will result in a lower maximum flow rate for a given temperature rise.
