TEMPERATURE CONTROL – DELUXE
BATH FILL MODE
The Bath Fill mode is designed to allow the water heater to deliver a selected volume of water at a selected
temperature. The Bath Fill mode commences when the BATH FILL button is on and a hot tap is opened.
When the set volume has been delivered, the water flow from the water heater ceases and heating stops. It
is also useful for controlling the water volume used by a shower or other application.
Note: The bath level should be monitored periodically while this function is in use to avoid the possibility of
the bath overflowing. The Bath Fill mode should be used with caution until you are familiar with its operation.
Warning: Baths should not be left unattended whenever young children are present. After using the
bath fill function, check the water temperature before entering a bath, to ensure it is suitable and will not
cause scald injury.
The Bath Fill mode can be set and turned off at any of the Deluxe controllers. Refer to the
