1. Con
fi
rm the AE-Ti heat pump and AquaLink RS
software revisions are compatible (see Figure 17).
NOTE
Only a revision "N", or higher, program chip in
the RS system will support the AE-Ti heat pump
interface.
2.
Turn off the power to both the heat pump and
the RS control and open the RS Power Center
enclosure and remove the front dead panel.
3.
Remove the two screws holding the bezel in place
and turn the bezel over to view the circuit board on
the back.
4.
Locate the programmed chip on the Power Center
Board. In the center of the chip is the revision
letter. If the revision letter is "
N
" or higher go to
step 5. If the revision level is "
MMM
" or lower,
replace the board.
5.
Use 22 gauge 4-conductor wire (Jandy Part No.
4278) to run between the heat pump and the RS
control, and match the wire color order.

The wires coming from the AE-Ti heat pump can
be “doubled up” on the red terminal bar with the
four wires coming from the indoor controller.
NOTE
If you need to install more than two wires in
each terminal, order a Jandy Multiplex PCB Kit,
which includes the Multiplex Board (Jandy Part
No. 6584). Never put more than two wires into
each of the pins of the terminal bar.
7.
Check all wiring, then apply power to both the
heat pump and the RS control system. Operation
can be veri
fi
ed in either Service or Auto mode. See
the RS Control System manual for instructions
about operation.
When the AE-Ti heat pump is first powered and
there is an RS control connected to the heat pump, the
display on the heat pump will show
"JANDY REMOTE
ONLINE PUSH MENU TO DISABLE"
. When the
AE-Ti heat pump is online with the RS control, all
functionality of the control on the heat pump is disabled.
The heat pump functions can be controlled only at the
RS unit.
To temporarily use the heat pump controls, press
the
MENU
button. The message
"JANDY REMOTE
ONLINE PUSH MENU TO DISABLE"
will disappear
from the heat pump display. All functionality has now
been returned to the control on the heat pump. In this
mode the RS unit is no longer controlling the heat
pump.
