AUTOSET
Autoset is a feature that allows the heat pump to automatically turn on your water circulation pump at
predetermined time intervals after the water circulation pump shuts off. To utilize this feature, the water circulation
pump must be wired in parallel with your mechanical time clock using the auxiliary relay supplied in the high
voltage power panel of the heat pump.
For example, if your pool water circulation pump is wired properly with the time clock through the heat pump,
have the heat pump control board programmed with a pump start time interval of 4 hours, have the AutoSet
feature enabled, and you wish to maintain your pool to 80° F., this is the sequence of events that will happen.
1. If your mechanical time clock is set to shut off at 9:00 p.m., once the water circulation pump shuts off,
the heat pump will display a countdown window.
2. The heat pump will continue to countdown in hours and minutes.
3. Once the 4 hours has expired, at 1:00 am, the control board will energize the internal contactor in the heat
pump to turn on your water circulation pump.
4. The heat pump will sense water temperature then determine if it needs to continue to circulate water. If
the pool temperature has fallen below your set point, 80 degrees for this example, the heat pump will turn
on and begin heating the pool. Once the pool temperature has reached its set point, 80 degrees, the heat
pump will shut off and will also shut off the water circulation pump.
5. If after the water sensing time, the heat pump detects the pool water is above the set point, 80 degrees for
this example, it will shut off and shut the water circulation pump off also.
6. At the time the water circulation pump shuts off, the heat pump will again reset and begin the countdown
interval again and display the following window.
7. The heat pump will continue this cycle every time the water circulation pump is shut off.
8. Once the time clock turns on in the morning, the heat pump will stop the AutoSet feature and resume normal
operation.
