Note: The temperatures indicated are approximate. The
actual temperature of the heated water may vary.
The Vacation Setting (VAC) sets the controller at
approximately 21°C (70°F). This setting is recommended
when the water heater is not in use for a long period of time.
This effectively turns the controller temperature setting
down to a temperature that prevents the water in the water
heater from freezing while still conserving energy.
