8) From the LOAD PCT screen, one press of the RIGHT button
will shift the display to the FLOWRATE screen. This shows the
rate of flow of water through the heater.
9) From the FLOWRATE screen, one press of the RIGHT
button will shift the display to the UNITS screen. This shows
the units of measure in either the ENGLISH or METRIC
systems. ENGLISH units are degrees Fahrenheit and gallons
per minute. METRIC units are degrees Celsius and liters per
second. Use the UP and DOWN buttons to select the desired
units of measure.
10) From the UNITS screen, one press of the RIGHT button
will shift the display to the SOFTWARE REVISION screen. This
shows the revision level of the software in the control.
11) From the SOFTWARE REVISION SCREEN, one press of the
right button will shift the display to the ERRORS screen. This
shows the error history of the heater. “0 ERRORS” means
that no errors have occurred.
If the heater has an error history of 4 errors: this history will
be displayed on the screen as shown. “CODE 1:E0” refers to
the first error and indicates it to be an E0 error. One press of
the UP button will show the second error as “CODE 2:E0”
error.
Continued pressing of the UP or DOWN buttons will scroll
through each of the errors in the history (in this case a total
of 4). ERRORS indicate an undesirable condition but will not
shut down the operation of the heater
Error Codes
E0: Excessive water flow detected
Corrective action: Using the OUTLET BALL VALVE, slowly reduce water flow until the desired temperature is achieved.
The temperature is proportional to the flow through the heater; the lower the flow, the higher the temperature and
vice versa.
CAUTION
Keep the INLET BALL VALVE fully “OPEN”. NEVER RESTRICT THE WATER FLOW USING
THE INLET VALVE.
E1: Inlet temperature too hot to generate heat
