Temperature Sensors
ATTENTION:
The water temperature sensor is 25’ long. Consider the sensor mounting locations BEFORE mounting the
System Control Center.

.
Locate the Air Temperature Sensor so that it will be
exposed to the outside ambient temperature but not
influenced by direct sunlight. If the System Control
Center is located in a building, route the sensor cable
through the wall of the building.

Secure the sensor with the clip and screw provided.
Avoid attaching the Air Temperature Sensor to
any surface that gets hotter than the ambient
air temperature.

TO INSTALL THE WATER TEMPERATURE SENSOR
The Pool System uses high quality 30K ohm thermistor type temperature sensors. Two sensors are provided (one for
Air and one for Water). If this control is used with a solar heating system, an optional solar sensor must be purchased
separately.
Note: Some major brands of pumps (Jandy, for example) may have different threads and may not be compatible with
this configuration. Also, a proper “T” configuration may need to be installed in the plumbing ahead of the heater.
FREEZE PROTECTION FEATURE
Freeze control is initiated when the air temperature falls to 34˚F - 40˚F (user selectable). Freeze control turns on the
filter pump in pool mode for 30 minutes, then continues running the filter pump in spa mode for 30 additional minutes.
This is repeated as long as the air or water temperature is at (or reaches) the preselected temperature. The user can
disable the air freeze function.
Note: This feature is designed to protect the pool equipment in the event of unforeseen or unseasonable freezing
conditions. It is not intended to take the place of proper winterizing procedures.

Run the sensor cable back to the low-voltage
compartment of the System Control Center and plug
the connector into the 2-pin header J9 labeled AIR.
