Main or Bath Control for Residential Models (Fig. 9)

NOTICE

The temperature can only be adjusted between 96°F and 110°F when the hot water tap is open and hot water is flowing. This is a safety feature to prevent scalding while hot water is in use.

Commercial Models (See figure 10):

1.Commercial models have the Main Control mounted on the front of water heater, which will allow the outlet water temperature to be adjusted from 96-180°F. Commercial models can only have one temperature control. If a remotely located Commercial Main Control is desired, then the front panel control must be disconnected and an optional Commercial Main Control (239-44510-00) must be purchased and installed.

2.All hot water faucets must be off to get the full range of temperature adjustment. The control will only allow an adjustment range of 96-110°F while hot water is in use to prevent scalds.

3.Press the “H” or “C” buttons until the desired temperature is shown on the display.

4.The water heater will automatically start heating water whenever a hot water faucet is opened. The Main Control will indicate hot water use with the green “IN USE” indicator.

5.The Main Control can also display diagnostic error codes, water flow rate through the unit (in gallons per minute) and the outlet water temperature.
