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.
