When the temperature in the pool is 1°C lower than the "Set" Temp., the heat pump will start
again.
Cooling Only Mode : (+ 2/ - 0°C '' from set point '' )
This works the same way, but will only cool when the temperature exceeds the cooling
"Set" Temp. by 2°C and it will cool down to the "Set" Temp.
Remember that the highest Cooling "Set" Temperature is 37°C.
Auto Mode : (''Automatically Heating Mode or Cooling Mode'' )
In Auto Mode your heat pump will try to keep your desired pool temperature at all times.
Example :
If you want your pool to be 30°C:
a. If the pool-water is below 29°C the heat pump will start heating.
b. When the temperature reaches 31°C the heat pump will stop.
c. If the temperature in your pool continues to rise, and passes 32°C, the heat pump will
start again, BUT in Cooling Mode, and cool down to 30°C.
d. If now the temperature continues to drop, and it drops below 29°C, the heat pump will
start again, BUT in Heating Mode.
In Auto Mode the heat pump will try to keep the temperature within 2°C higher and 1°C
lower that your "Set" Point.
