Amount of Hot Water
Problems
What to do
Display Window
The amount of hot water
in the tub is less/more
than the set amount when
using the flow meter alarm
feature.
When hot water is used for other fixtures while filling
the bath tub, the tub will not fill as much.
If there is water in the tub already, or when filling is
stopped and restarted, the tub will fill more.
The flow meter alarm does
not sound even when filled
to the set amount.
The flow meter alarm is set to sound when hot water is
continuously discharged for the set volume of water.
If mixing valves are used, or if cold water is mixed
with hot water at the fixture, the tub will fill more than
the setting of the flow meter alarm.
Amount of hot water
available has decreased
over time.
Is the water filter clogged? (
p.23)
If the supply water is hard and has not been treated,
scale can build-up in the water heater and decrease
the maximum amount of hot water available. Scale can
be removed from the water heater by flushing the unit
periodically. To prevent scale from forming in the water
heater, a water softener or scale inhibitor is recommended.
Optional Remote Controller
Problems
What to do
Display Window
The light on the power
button does not come on.
Has there been a power failure?
Is the power connected properly?
The water temperature changes
after a power failure or when
the power is disconnected.
The temperature setting and the flow meter alarm
setting may both need to be reset after a power
outage.
The plastic on the surface
or buttons of the remote
controller has torn,
peeled, or air bubbles
inside.
The surface of the remote controller is affixed with a
protective sheet (to prevent surface scratching, etc.) at
time of shipment. This sheet can be removed or left as it
is. When leaving the protective sheet on, areas frequently
touched may tear or peel. However, the remote controller
will not malfunction from water entering such torn or
peeled areas. To restore the appearance of the remote
controller surface, simply remove the protective sheet.
