5) CONTROL FEATURES
BEFORE USING THIS CONTROL, MAKE SURE ALL PRIOR INSTALLATION STEPS HAVE 
BEEN PROPERLY COMPLETED, ELECTRICAL POWER IS ON AND WATER IS PRESENT 
IN THE HEATER. 
PUSH BUTTON FLOW CHART
1) The SETPOINT TEMP or ACTUAL TEMP screen can be
selected for display as the home screen. Either of these 
screens will remain on the display when the backlight timer 
expires.
2) There is a 5 minute time delay built into the control. 
Regardless of which screen is being displayed, after 5 
minutes of inactivity, the display will revert to the SETPOINT 
TEMP screen.
3) The 4 push buttons are used to control the operation of 
the heater. The LEFT and RIGHT buttons shift the display 
from one screen to another. The DOWN and UP buttons 
may change the values within selected screens.
4) As an example, when the screen displays SETPOINT 
TEMP, the desired hot water temperature will increase 1 
degree for each press of the UP button and decrease 1 
degree for each press of the DOWN button. Note that 
minimum and maximum setpoint temperatures are 
established at the factory.
