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.

1. 

Connect two #14 gauge wires, designed for 
use in hot en vi ron ments, to the #1 and #2 
terminals on the green, 10-pin Terminal Bar.

2. 

Connect the other ends of the #14 gauge 
wires from Step 1 to the Fireman's Switch 
terminal bar in place of the factory installed 
wire loop. 

3. 

Do not disconnect high limit or pressure 
switches.

4. 

Turn the heater thermostat(s) to maximum 
setting.

5. 

Turn the heater switch to the ON position. 
For dual thermostat heaters turn switch to 
Spa position.

1. 

Remove the LX GUI from the heater.

2. Confi rm 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).

NOTE  If connecting more than two (2) items to the RS 

Power Center red, 4-pin con nec tor, a Multiplex 
PCB is required.
