Using the Water Smart / Bath Fill Function
Overview
This function is exclusive to the BC-100V temperature
controller. The bath fill function allows the consumer
to fill a tub with a preset volume of water at a preset
temperature. This is done by pressing the bath fill
button on the BC-100V controller while no hot water is
flowing and then opening only the hot water tap. The
water heater will stop the hot water flow when the
preset volume has been reached. The hot water tap
should then be closed and the bath fill button pressed.
The temperature settings for the bath fill function are
limited to those in the table below.
Power
Loss
If power is lost during the bath fill
function, the water heater will shut
down but the water will continue to
flow. When power returns, the water
shuts off and Error Code 03 appears
on the controller.
If power is lost after the bath has filled
but before the bath fill function button
is de-selected, then the water will not
flow during the power loss or after the
power is returned. Once power
returns, close the hot water tap and
de-select the bath fill function. No
error code appears.
NOTICE
Multiple
Water
Heaters
The bath fill function will not work
properly if it is connected to multiple
water heaters. The tub will overfill
because the bath fill function is not
able to measure the water volume
when connected to multiple water
heaters. NOTICE
