NOTE:

When power is initially

 

applied to a new water heater, the control points will be pre-programmed. The factory final quality test sets the unit for test firing. The preset values are as follows:

Stage

Set Point

Differential

1

125˚ F

2˚ F

2

123˚ F

2˚ F

3

121˚ F

2˚ F

4

120˚ F

2˚ F

Re-program the set points and differentials to meet your system hot water requirements.

The operating control uses a Liquid Crystal Display for interactive prompting during programming and display of sensed and assigned set point and differential values. Programming is accomplished through the use of the four programming keys.

TEMPERATURE ADJUSTMENT

1.Turn “OFF” the electrical power to the water heater. If the power disconnect point is out of sight, lock it in the open (“OFF”) position and

tag to prevent unexpected application of power.

2.Open the water heater’s electrical access panel.

3.Verify that the unit is properly applied and the model number on the rating plate correctly identifies the unit.

4.Turn the electrical power switch to the “ON” position. The control will begin counting down from 210. This countdown sequence will last for approximately 3-1/2 minutes.

WARNING:

HAZARD OF ELECTRICAL SHOCK – Full power is present whenever the cabinet door is open and the main power disconnect is in the “ON” position, even with the pilot switch(es) turned off.

5.To override this time delay, press Select.

6.Press Select to display the current stage set point.

7.Press Up Arrow key to increase or Down Arrow key to decrease to the desired set point.

8.Press Enter to enter the displayed value into memory.

9.Press Select to display the current stage switching differential.

10.Press Up Arrow key to increase or Down Arrow key to decrease to the desired switching differential.

11.Press Enter to enter the displayed value into memory.

12.Repeat steps 6 through 11 to program each additional stage.

13.Press Select, Select, Select, Select (4 times) to return to stage 1 parameters. Scroll through the programming loop a second time to confirm that the appropriate values have been entered into memory by pressing Select.

14.Press Select after viewing the switching differential for the final stage to display stored water temperature.

15.Close the water heater’s electrical access panel.

16.The temperature control is now ready for operation.
