The 2
nd
stage (HPPH) demand is initiated when
water temperature has remained more than 0.5
°
F
(0.3
°
C) colder than the heat setpoint for more than

°
F
(0.8

Remote Pool Operation
REMOTE Mode is accessed by pressing and holding
the UP and DOWN buttons simultaneously for 3 sec-
onds. When exiting the REMOTE mode, the control
always selects the OFF Mode. 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 temperature setpoints are not
changed. Press and hold the UP and DOWN buttons
for 3 seconds to exit REMOTE Mode.
On HEAT/COOL models, the control displays “Remote
Pool” on the first line of the display while the 2
nd
line
displays “Cool”, “Heat” or “Auto”. Factory default is
“Cool”. The control uses the value selected when the
MENU button is pressed to advance to the next item.
This programming is done from the Installer/Service
menus.
Pool Heat Mode
The control is equipped with a mode which will
automatically heat the pool to the heating setpoint
established in the User’s menu.
Pool Cool Mode (HEAT/COOL models ONLY)
The control is equipped with a mode which will
automatically cool the pool to the cooling setpoint
established in the User’s menu.
Pool Auto Mode (HEAT/COOL models ONLY)
The control is equipped with a mode which will auto-
matically heat and cool the pool within the range of the
heating setpoint plus the Cooling Deadband (2-10
°
F
(1.1-5.5
°
C) adjustable – default 6
°
F (3.3
°
C)) estab-
lished in the Installer/Service Sub-menu. Example
– pool heating setpoint set at 80
°
F (27
°
C) and Cooling
Deadband set at 6
°
F – unit will automatically heat the
pool if the temperature drops below 80F (27
°
C) and
will automatically cool the pool if the temperature is
above 86
°
F (30
°
C).
TIMED SPA Mode
The control is equipped with a mode which will heat
the spa to the Spa Setpoint temperature for a specified
period of time selected in the TIMED SPA mode set-
up. NOTE: The Spa setpoint temperature CANNOT
be changed when operating in this mode. This func-
tionality will override all other program settings for the
period of time selected by the user during the TIMED
SPA initiation.
WARNING:
If the Spa heating (in a pool/spa
system) is controlled by an external controller, 3-way
valves MAY need to be manually adjusted in order to
use the TIMED SPA feature of this HPPH. Failure
to properly adjust the 3-way valves may result in
overheating of the pool water or other undesirable
results.
1. To activate the TIMED SPA feature, press the
MENU button until “TIMED SPA” is displayed on
the top line of the display.
2. Press the UP or DOWN buttons to select the
desired duration of spa heating (up to a maximum
duration of 6 hours in 15 minute increments).
3. The timer will start to count down from the selected
period of time and the HPPH will operate to heat
the spa water based on the previously selected
spa setpoint temperature setting.
4. When the TIMED SPA timer has expired, the
control will return to the previous mode that it was
in when TIMED SPA was selected.
Fault History
The control is equipped to maintain fault history in
the Installer/Service menu. It will retain the last 10
faults (starting with the most recent). If the fault history
exceeds 10 events, the earliest fault drops off when a
new fault occurs. NOTE: There is no time/date stamp
associated with each fault. This history is intended to
simply show what faults the unit has experienced.
When the “Faults Last” shows on the display, press-
ing the UP button toggles to the most previous fault.
Pressing the UP button toggles through the recorded
faults. The faults are labeled on the first line of the
display as Faults Last, Faults 2, Faults 3, etc.
Consecutive identical faults are only stored once.
Run Hours/Cycles
The control is equipped to monitor the number of run
hours of the unit and the cycles of operation. This is
accessible through the Installer/Service menu. These
values are not resettable. The “Run Hours” tracks
the number of hours that the compressor has been
energized. This data is stored in non-volatile memory
each time the demand for heat is satisfied. Hours and
minutes are stored, although only hours are displayed.
The “Cycles” tracks the number of times that the com-
pressor has been energized.
