The Switch is designed to switch a 240Vac pump maximum rated to 9.98 Amps 2395 watts from the switch inputs. This unit is designed to be plugged into a general power outlet and the heating priority connections on the heat pump.
The heat pump is designed to heat or cool the water of the pool only when the water circulates through it. By connecting the Switch to the heat pump, and then the circulation pump to the Switch, the heat pump will control when the circulation pump is run. This system allows the heat pump to maintain the set-point temperature in either heating or cooling mode.
Every 60 minutes, the circulation pump is started for 2 minutes to sample the water temperature. If after 2 minutes, the temperature of the water is below/above the required set-point temperature (depending if in heating or cooling mode), the circulation pump will be turned off for a further 60 minutes before sampling the water temperature again.
If the heat pump senses that the water has cooled/heated below/above the temperature set-point, the circulation pump and the heat pump will continue to operate until the desired set-point temperature is reached.
By following the instructions in the heat pump instruction manual, setting a start and stop time will ensure that the heat pump is not sampling the water temperature and running throughout the night if running noise is a factor.
