heat temperature settings are displayed on the main screen. The heater is active when the set temperature is
higher than the water temperature. The heater will switch off when the water temperature rises above the set
temperature.

and off the heat source and filter pump. A heat selection must be selected in the Heat menu before the heater
is activated. The “Manual Heat” setting does not function with the LO-TEMP circuit. The heater is active
when the set temperature is higher than the water temperature. The heater will switch off when the water
temperature rises above the set temperature.
