10.2Operating Temperature Control

An adjustable digital operating control is located in the front control panel. The control is factory pre-set at approximately 120ºF. To adjust the setpoint to deliver the desired water temperature, press and release the Set 1 key on the face of the control. When setpoint adjustment is enabled, use the arrow keys to adjust the set point to the desired system temperature. See TempTrac Electronic Controller Panel in this manual for more information.

10.3High Water Temperature Limit Control

Appliances are equipped with adjustable limit and high limit controls to control the maximum discharge water temperature. These controls are located inside the control cabinet and are accessed by removing the bottom cover. The high limit control is optionally available as the manual reset type and may be reset by pressing the limit reset button accessible through the control panel cover. Pressing the reset on the High Limit Control will not cause the control to reset until the water temperature has dropped below the set point of the manual reset High Limit Control. The Lower Limit is of the auto reset type and can be dial adjusted to operate just above the set point of the main Operating Temperature Control.

10.4Cathodic Protection

PVI water heaters do not utilize cathodic protection. However, in hot water systems utilizing cathodic protection, hydrogen gas can be produced when the hot water system has not been used for a long period of time (generally two weeks or more). Hydrogen gas is extremely flammable. To prevent the possibility of injury under these conditions, one of the hot water system faucets should be opened for several minutes before using any electrical device connected to the hot water system. If hydrogen is present, there will be an unusual sound such as air escaping through the pipe as the hot water begins to flow. Do not smoke, have open flames or turn electrical switches on or off near the faucet at the time it is open.

10.5Electronic Low Water Cut-Off (Optional)

When the water level is above the electrode position in the tank, the reset pushbutton will energize the control (LED will be lit). The control remains energized until the water level recedes below the electrode position (LED will not be lit). Unless otherwise specified, there is a three-second time delay on decreasing level. Water level must be below tank probe location for full three seconds before control de-energizes.
