PROGRAMMING

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.
