WARNING: If an external controller controls the spa
heating in a pool/spa system, manual adjustment of the
3-way valves may be necessary to use the TIMED SPA
feature of this heat pump. Failure to adjust the 3-way
valves properly may result in pool water overheating or
other undesirable results.
To activate the timed spa feature, press the MODE key until
“TIMED SPA” is displayed on the top line of the display.
The display will read “Up or Dn to Set”. This tells the user
to press the UP or DOWN keys to set the desired length of
time for the timed spa heating operation.
Press the UP or DOWN keys to select the desired duration
of spa heating, up to a maximum duration of 6-hours in
15-minute increments. After selection of time is completed
press MODE key to start heater operation.
The timer will start to count down from the selected period
and the unit will operate to heat the water based on the
previously selected spa setpoint temperature setting.
Once the unit turns on, the display will toggle between the
current spa water temperature and the current operating
state “Heating” and the timer.
The top row of the LCD displays the operation mode and
temperature setpoint. Timed Spa temperature setpoint
can be adjusted using the UP and DOWN keys while the
screen is displaying the Water Temperature and “Heating”
status.
To adjust the timer, press MODE key, then use the UP and
DOWN keys to increase or decrease the timer. To terminate

Pool Cool Mode - Heat/Cool Models Only
In heat/cool models, the control is equipped with a "Pool
Cool Mode" which will automatically cool the pool to the
cooling setpoint established in this mode.
The top row of the LCD displays the operation mode and
temperature setpoint. When pool cool mode is selected,
each press of the UP or DOWN key will increase /
decrease the water cooling setpoint temperature. Holding
the UP or DOWN keys down will speed up the change of
the temperature values.
In this mode, the heater is set to cool when the water
temperature is 1°F (0.5°C) degree above the selected
temperature (setpoint). Cooling is terminated when
setpoint is reached.
When the water temperature is below the setpoint, the
LCD will alternate “Water Temp” with “No Demand.” When
the water temperature is above the setpoint and the unit
is cooling, the display will alternate “Water Temp” with
“Cooling”.
In pool cool mode, default temperature setpoint is 80°F
(27°C) with a minimum temperature of 44°F (7°C) and
maximum temperature limit of 95°F (35°C). Refer to
"Program Menu", on page 18, to adjust pool maximum
temperature limits.
