Heater Connection
The heater connection section applies to all
heaters or heat pumps with thermostatic circuitry
of 24 VAC or less (see pages 15 thru 17 for brand
specific installation).
NOTE
If you are connecting a heater with thermostatic
circuitry of 120 VAC or greater, do not connect
to the green, 10-pin Terminal Bar. Instead,
connect the heater to a high voltage relay in
the Power Center and plug the spare relay into
the Electric Heater relay socket located on the
upper right hand corner of the Power Center
PCB.
3.4.1 Jandy Brand Heater Connections
1. Connect two #14 gauge wires, designed for

terminal bar in place of the factory installed
wire loop.
3. Do not disconnect high limit or pressure
switches.

1. Remove the LX GUI from the heater.
2. Confirm the LX and AquaLink RS software
revisions are compatible (see table).
3. Run a 4-conductor cable from the LX GUI
red, 4-pin connector to the RS power Center
red, 4-pin connector (see Figure 10).
