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.
