- 1). Press the "Temperature" dial once and turn the dial to change the current temperature of the heating unit. When the temperature you want the unit to reach is on the display, leave the dial alone. The unit will turn on and operate until it reaches this temperature and then will shut off.
- 2). Press the "Daytime Room Temperature" button to begin setting the programmed temperature for the daytime. In the same manner as setting the temperature in the above step, turn the temperature dial until the desired temperature is displayed on the screen. Press the "Daytime Room Temperature" button once more to save the setting. Your heating unit will keep a steady temperature during daytime hours.
- 3). Press the "Nighttime Room Temperature" button to set the temperature for standard water during the night time hours. This temperature can be lower than during the day to save power, and is set using the same method you used in the above step for the daytime button. Use the "Temperature" dial to set the number and press the "Nighttime Room Temperature" button again to save.
- 4). Press the "Daytime Room Temperature" button to set the programmed temperature for the daytime. As with setting the temperature in Step One, turn the temperature dial until the desired temperature is displayed on the screen.

- 5). Press the "Daytime DHW Temperature" button to set the maximum daytime temperature of your water. This will set the top range for how hot the water will get when you turn on the hot water while using the shower or sink. Use the "Temperature" dial once again to set the temperature and the "Daytime DHW Temperature" button again to save.
