Unchecked—The program is in comparison mode.

The heat pump system's operating costs are compared to the cost of operating the existing heater.

Checked—The heat pump is in backup mode.

Use the option to activate the existing heater when the heat pump capacity is below the capacity required to maintain the pool at the set temperature, which otherwise would cause a temperature drop in colder months.

The program will calculate the additional cost of using the backup heater. This function is only activated when the heat pump capacity is too small to maintain temperature.
