Remote Controller

The light on the power button does not come
on.
The water temperature changes after a
power failure or when the power is discon-
nected.
The plastic on the surface or buttons of the
remote controller has torn, peeled, or air bub-
bles inside.

Sounds

The fan can be heard after operation is
stopped. A motor can be heard when turning
the unit ON or OFF, when opening or closing
a fixture, or after the unit has been running for
a while.
Table 13

Has there been a power failure?
Is the power connected properly?
The temperature setting and the flow meter alarm setting may
both need to be reset after a power outage.
The surface of the remote controller is affixed with aprotective
sheet (to prevent surface scratching, etc.) at time of shipment.
This sheet can be removed or left as it is. When leaving the pro-
tective 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.
These noises indicate the proper operation of devices which are
designed to let the unit reignite more quickly, and ensure the
water temperature is stable.
