Troubleshooting
Control Fault 7
Interrupt Error.
Auto reset in 1 hour or Recycle control – replace control if fault
continues.
Control Fault 8
Time of Day Clock Failure.
If the control is unable to read the time of day clock, it logs the
fault and disables scheduled pump and aux output settings. Time
is displayed as ??:?? in this condition. Recycle control – replace
control if fault continues.
Service Call Verification
Before you make a service call,
first
determine if the
problem is:
• Warranty Service - must have model number,
serial number and date of installation or Warranty
Registration confirmation number.
• Unit operation (power supply, water flow, or time
clock adjustment)
Power Supply
• Verify that all circuit breakers are reset and
working properly.
• If the temperature display on the control panel still
does not light, contact the installing dealer, since it
may be a power problem requiring an electrician.
Water Flow
• Verify that the pool filter is clean to provide good
flow.
• Verify that valves are properly positioned to allow
adequate water flow through the unit.
Time Clock Adjustment
Verify that the time clock is set to permit the unit to run
long enough to heat properly.
Set Factory Defaults
If programming is messed up and no operation can
reliably be made, the control board can be reset to
Factory Default values as noted in Table D, E or
F. This operation changes all adjustable settings to
factory default settings.
Enter the Installer/Service Mode by holding the MENU
and UP buttons for 3+ seconds. Scroll through the
information until you reach the “Installer Menu” screen
NOTE:
The
MANUFACTURER IS NOT RESPON-
SIBLE
for these adjustments.
NOTE:
The Service number is located on the front
of the HPPH at the brand label.
- press the UP or DOWN button until YES appears on
the 2nd line. Press the MENU button to access the
additional Service information. Continue to press the
MENU button until “Set Factory Defaults” appears on
the display. Press and hold the UP and DOWN button
for 5 seconds to reset the control to factory defaults.
The display will read “Defaults Set” when completed.
Service Access to Heaters
If service access to the heater is required, it is
accomplished by removing the control panel to provide
a wide access to get to (1) compressor, (2) heat
exchanger, (3) TXV, (4) reversing valve/solenoid
valve (if equipped), (5) flow switch (if equipped), and
(6) sensors (water, ambient and coil). To gain access,
follow the steps below:
1. Shut off all power to the unit to avoid any possibility
of electrical shock or damage to components.
2. Remove the 5 screws securing the control panel
cover from the cabinet (2 each side and 1 in the
top panel – see Fig. 10 below). Place the screws
in the recessed cups in the molded base.
NOTE:
Previous settings will be erased and are
no longer recoverable. All settings will have to
re-entered by hand to re-establish proper operation.
