Installation & Operation Manual
Do not connect more than two (2) wires to any of the
terminals in the Control System when connecting
peripheral devices. If connecting the heater to the control
system creates this situation, then a Multiplex PCB
kit must be used. Call your distributor or Zodiac Pool
Systems, Inc., to order the kit.

Spare
Figure 26. PCB with firmware REV N or higher
If your PCB firmware is REV MMM or lower, connect
via a 2-wire connection. See Section 6.5.2
.
If your PCB firmware is REV N or higher:
1.
Turn off the power to both the heater and the
controller.
2
Open the power center enclosure and remove the
front dead panel.
NOTE
Only an AquaLink
®
RS System with firmware revision
"N", or higher, will support the heater interface. Refer
to Table 7 and Figures 25 and 26 to determine the
REV of your system's firmware. If it is "N" or higher,
continue with these procedures. If it is MMM or lower,
follow the procedures in
Section 6.5.2
.
NOTE
Only a PDA System with firmware revision 4.1, or
higher, will support the heater interface.
3.
Use 22 gauge 4-conductor wire to run between
the heater and the RS control and match the wire
color order (Figure 24).
4.
The wires coming from the heater can be
“doubled up” on the red terminal bar with the four
(4) wires from the indoor controller.
NOTE
If you need to install more than two (2) wires in each
terminal, order a Zodiac
®
Multiplex PCB Kit, which
includes the Multiplex Board (Zodiac part # 6584).
Never put more than two (2)wires into each of the pins
of the terminal bar.
5.
Check all wiring, then apply power to both the
heater and the control system. Verify operation
in either Service or Auto mode. Refer to your
Control System manual for operating instructions.
