Product details

The Jandy 7784 is the air and solar temperature sensor kit, supplied as one kit covering both sensor positions.

What the sensors do

Solar heating only makes sense when the panels are actually warmer than the pool. A control works that out by reading temperature at more than one point, and the air and solar sensors are two of those points. When a sensor drifts or fails, the control keeps acting on the number it is given, so the symptom looks like bad logic rather than a bad part.

Before you order

The facts available for this listing cover the kit and its part number rather than a full compatibility list, so check part 7784 against your control documentation before ordering.

Questions and answers

What people ask about this product, answered by our pool techs.

What is in the kit?
It is the Jandy air and solar temperature sensor kit, part 7784, covering both sensor positions.
Why do these sensors matter?
A control compares solar temperature against air and water temperature to decide whether running solar is worth it. If either reading is wrong, the system heats when it should not or refuses to heat when it should.
How do I know a sensor has gone bad?
Readings that sit at an implausible value, never change, or disagree with a thermometer at the same spot point at the sensor rather than the control.
Will it work with my control?
Check part number 7784 against your control documentation before ordering. The facts here list the kit and its part number, not a full compatibility list.
