AutoSet
Enable this feature any time the filter pump is off. The AutoSet feature periodically energizes a contactor which can be
connected to the pump to move water through the heat pump. This allows the heat pump to sense the water
temperature.
If the temperature is not at the desired level, the heat pump starts, along with the filter pump, 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 intervals (1-4 hours) to control when the heat pump senses the water temperature. Use
AutoSet to maintain the desired pool water temperature.
To use this feature:
Be sure the water circulation pump is wired in parallel with a mechanical time clock, using an auxiliary (24VAC
powered) relay that should be connected to the 'pump' terminals on the main terminal block. (see installation
instructions on page 11 ).
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 ENABLE and DISABLE options.
3 Set the interval (1-4 hours) from the control panel to control when the heat pump sends a signal to check the
water temperature.
For example, if you program the heat pump control board with a pump start time interval of 4 hours, have the AutoSet
feature enabled, and have a desired water temperature of 27°C (80° F ), this is the sequence of events that will happen:
1. The heat pump displays a countdown window after the filter pump shuts off.
2. After four (4) hours, heat pump will switch on and start the filter pump depending on the temperature set point.
3. The heat pump will sense water temperature then determine if it needs to continue to circulate water.
4. 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.
5. 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.
6. Once the time clock turns on in the morning, the heat pump will stop the AutoSet feature and resume normal
operation.
Extend
This feature will extend the filtration pump timing until the set point is reached. To use this feature:
Be sure the water circulation pump is wired in parallel with a mechanical time clock, using an auxiliary (24VAC
powered) relay that should be connected to the 'pump' terminals on the main terminal block. (see installation
instructions on page 11 )
To enable the Extend feature:
1 Press the MENU SELECT button repeatedly until the Extend screen is displayed.
2 Press the UP or DOWN arrows to toggle between the ENABLE and DISABLE options.
3 When the set temperature is not reached when the normal filtration cycle stops, the heatpump will override the
timer and keep running water through the heatpump until the set temperature is reached.
