6.5.2 Connecting to an AquaLink® Control System
or Remote TSTAT (2-Wire Connection)
An interrupt (on/off-type) remote can be connected as
a Remote TSTAT to turn the heater on or off but not
perform any other function. When using this type of
connection, remember to set the heater control to “SPA”
and set the thermostat control to maximum.
Consult with the Zodiac Pool Systems, Inc. Technical
Support Department, 800.822.7933 (in Canada:
888.647.4004), for questions about installing non-Zodiac
remote controls.
Install the Remote TSTAT:
1.
Turn off the power to both the pool/spa control
system and the heater unit.
2. Remove the front panel door.
3.
Run the wires from the pool/spa control system
through the opening located on the lower right or
left hand side of the heater.
4.
Connect the wiring from the pool/spa control
system to the heater remote control terminal.
5.
Connect the two wires to Pool and Common (not
Spa) on the J6 terminal bar.
6.
Reinstall door panel.
7.
Restore power to the heater and the pool/spa
control system.
NOTE
If you install a time clock to control the filter pump
operation, it is recommended that the time clock have
its own low voltage (Fireman’s) switch to turn off the
heater before turning off the pump. The switch should
shut off the heater about 15 minutes before the filter
pump shuts off. This will allow for a more efficient
operation by removing any residual heat contained in
the heat exchanger back to the pool.
CAUTION
To avoid damage to the heater,
do not
connect the
power supply of the heater to the output side of
the clock
if your time clock simply interrupts the high
voltage power supply or has a high voltage output. Do-
ing so will prevent the blower from purging the residual
heat from the heater when the heater turns off. The
blower must be allowed to run for 45 seconds after the
heater shuts off.
Configure the Control Panel:
1.
Make sure the control is OFF.
2.
Press and hold MENU, then the POOL and SPA
buttons for 5 seconds to access Service Setup
mode.
NOTE
The display will revert back to
OFF
after 1 minute

6.5.3 “Smart” Communication via RS-485
To provide “smart” communication between the JXi and
a power center board (PCB) (AquaLink RS, AquaLink
PDA, and AquaLink Z4) through a red four-pin RS485
connector, your PCB must have the appropriate firmware.
To determine the REV of the AquaLink RS PCB firmware
in your system, refer to Table 7.
