Amount of hot water

• When hot water is demanded at other fixtures, the
amount available may be reduced.
• Pressure fluctuations and other plumbing conditions can
cause the temperature and pressure at a fixture to be
unstable, but it should stabilize after a short time.
• To keep the temperature stable, the heater limits the
amount of water that can flow through it to a small
amount initially, but the amount increases over time.

power is reconnected, the clock on the display screen
