AutoSet
The AutoSet feature periodically energizes a contactor which can
be connected to activate the filter pump. The heat pump can now
start and stop the filter pump independent of the time clock, allowing
the heat pump to circulate water and sense water temperature.
Enable this feature any time the filter pump is off.
If the temperature is not at the desired level, the heat pump starts
and runs until the water reaches the desired temperature. The
filter pump and the heat pump will stop when the water reaches
the desired temperature.
AutoSet allows you to set the time interval between the end of
the circulation cycle and when the heat pump reactivates the filter
pump to sense the water temperature.
To use this feature:
Be sure the water circulation pump is wired in parallel with a
mechanical time clock, using the auxiliary relay supplied in the
high voltage power panel of the heat pump.
To enable the AutoSet feature:
1. Press the MENU SELECT button repeatedly until the
AutoSet screen is displayed.
2. Press the UP or DOWN arrows to toggle between the ON
and OFF options.
3. Set the interval (1-4 hours) from the Pump Start Time menu
within the Service Menu tree to control when the heat pump
sends a signal to check the water temperature.
For example, if you select a Pump Start Time interval of four
(4) hours, have the AutoSet feature enabled and have AutoSet
Override set to ON, this is the sequence of events that will
happen:
1. The heat pump displays a countdown window after the filter
pump shuts off.
PUMP START DELAY
REMAINING 4:00
2. After four (4) hours, heat pump will switch on and start the
filter pump to sense the water temperature.

3. If the pool temperature has fallen below your Set Point, the
heat pump will turn on and begin heating the pool. If the pool
temperature is above the Set Point, the heat pump and filter
pump will shut off.
4. At the time the water circulation pump shuts off, the heat pump
will reset and begin the countdown interval and display 'Pump
Start Delay' again.
5. The heat pump will continue this cycle every time the water
circulation pump is shut off.
6. Once the time clock turns on in the morning, the heat pump
will stop the AutoSet feature and resume normal operation.

Extend
The Extend feature can energize a contactor which can be connected
to activate the filter pump. This allows the heat pump to start and
stop the filter pump independent of the time clock, allowing the heat
pump to circulate water and sense water temperature.
If the temperature is not at the desired level, the heat pump starts
and runs until the water reaches the desired temperature. The
filter pump and heat pump will stop when the water reaches the
desired temperature.
To use this feature:
Be sure the water circulation pump is wired in parallel with the
mechanical time clock and the auxiliary relay installed on the
high voltage panel of the heat pump.
To enable the Extend feature:
1. Press the MENU SELECT button repeatedly until the Extend
screen is displayed.
2. Press the UP and DOWN arrows to toggle between the ON
and OFF options.
For example, if you have the Extend feature enabled and the Extend
Override set to ON, this is the sequence of events that will happen:
1. After the filter pump shuts off, the heat pump immediately
senses the water temperature.
2. If the water temperature is below the Set Point the heat pump
will start the filter pump and begin heating the pool. If the water
temperature is above the Set Point the heat pump and filter
pump will shut off.
3. Once the time clock restarts the filter pump, the heat pump
will stop the Extend feature and resume normal operation.
