OPERATING THE PUMP 18/20
THERMAL MODE
The sensor for Thermal Mode is in the drive, on top of the motor. This feature allows you to
set a speed (450-3450 RPM) that runs when the IntelliFlo® VSD2 Variable Speed Pump goes
into Thermal Mode. The temperature level that you wish Thermal Mode to start can also be
set.
IMPORTANT NOTE: This feature is for protection of the pump. Do not depend on the Thermal
Mode feature for freeze protection of the pool. Certain situations could cause the pump to
sense a different temperature than actual air temperature.
Your automation systems air temperature sensor should be used to sense actual temperature.
For example, if the pump is located indoors, the temperature of the room does not indicate
the outdoor temperature. The pump does not sense the water temperature.
