play will show “Hi Press Trip”. If the high pressure
switch trips 7 times in a single cycle, the display will
show “Hi Press Lockout” and the unit will be locked out
of operation for 4 hours. The unit will automatically
reset after 4 hours or the lockout can be manually
reset by pressing the MENU button or cycling the
power. The high pressure switch must close for 3 sec-
onds for the control to recognize it as closed.
Low Pressure Switch Lockout
The control ignores an open low pressure switch for
the first 30 seconds after the compressor is energized.
If the low pressure switch opens for 3+ seconds any
time after this 30 second period, the compressor will
shut down and “Lo Press Trip” will show on the display.
If the low pressure switch trips 6 times in a single
cycle, the display will show “Lo Press Lockout” and the
unit will be locked out of operation for 4 hours. The
unit will automatically reset after 4 hours or the lockout
can be manually reset by cycling the power. The low
pressure switch must close for 3 seconds for the con-
trol to recognize it as closed.
Water Flow Switch
The control monitors the water flow switch. If the
pump has run for 3+ seconds, there is a demand for
compressor and the water flow switch is open, the
control will prevent the compressor from running and
show “Water PS Open” on the display. The water flow
switch is checked to ensure that it is open BEFORE
allowing the 3-way valves to switch. This ensures that
the pump is OFF before trying to change the 3-way
valve positions.
Sequence of Operation
1. Upon initial application of power, the HPPH control
briefly sets all segments on the LCD at power-up.
2. The control displays the current software revision
and the model type configuration (HEAT/COOL for
these models) on the LCD for 2 seconds and then
resumes the user selected mode it was in before
power was interrupted.
3. Setpoints are read from non-volatile memory. If
the checksum of the setpoints indicates corrupted
values, “EEPROM Fault” is displayed on the LCD
and operation is inhibited until setpoints are manu-
ally set.
4. If unit type has not been set (like during the
replacement of the HPPH control), the control
prompts the user to set the model type before any
device operation is enabled.
5. Upon initial installation, there are several items
that must be defined and programmed depending
on the configuration and accessories intended to
be controlled by the HPPH control. These include:
(1) 3-way valve control (Yes or No), (2) Pump con-
22
trol (Yes or No and then what type of control – 4-
speed control or variable speed control), (3)
Auxiliary control (Yes or No and then what type –
External Heat, Auxiliary Output or Remote Output).
6. Once these choices are made, then additional
information relating to the establishing of pump
periods, pumps speed during each period and
Return/Suction Valve positions during each period
must be determined and set in the control.
7. The options for the control can be very simple or
quite complicated, depending upon each installa-
tion desires.
8. Once programming is completed, the control is
ready for operation.
9. The user may select “On” for several operating
modes depending on the unit type. Each mode is
selected by pressing the MENU button to cycle
between the modes. Each press of the MENU but-
ton selects the next mode. There is no automatic
increment from continually pressing the MENU
button. In fact, continually pressing the MENU
button (for 3+ seconds) will move the user into the
USER Menu.
10. For HEAT/COOL models, the mode selections are
OFF – POOL COOL – POOL HEAT – POOL AUTO
– SPA – TIMED SPA.
11. REMOTE Mode is accessed by pressing and hold-
ing the UP and DOWN buttons simultaneously for
3 seconds. When exiting the REMOTE mode, the
control always selects the OFF Mode.
12. If the UP, DOWN or MENU buttons are pressed
while in REMOTE mode, the display will read “Exit
Remote Mode to Adjust Temp”. Mode and temper-
ature setpoints are not changed.
13. Press and hold the UP and DOWN buttons for 3
seconds to exit REMOTE Mode.
14. When operating, the unit will continue to operate
until the water temperature is 0.5F above/below
setpoint (below for cooling), until a defrost condi-
tion is needed or the unit is manually turned off.
15. The unit will remain in standby waiting for the next
heat/cool demand.
Controls
Your heat pump pool heater incorporates digital safe-
ty controls and indicators to ensure its safe, reliable
operation.
Water Flow Switch:
Prevents operation when the
pump is OFF. The unit requires 20 gpm minimum
water flow for unit operation.
Digital Water Temperature Control:
The pool water
temperature is controlled by the heat pump pool
heater’s digital control system, which gives you the
option of two settings: one for the desired spa tem-
