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 # 6584). Never put more than two wires
into each of the pins of the terminal bar.
5. Check all wiring, then apply power to both the
heater and the RS control system. Operation can
be verifi ed in either Service or Auto mode. See
your RS Control System manual for instructions
about operation.
When the LXi heater is fi rst powered on and
there is an RS control connected to the heater, the
display on the heater control will show "JANDY RE-
MOTE ONLINE PUSH MENU TO DISABLE".
When the LXi heater is online with the RS
control, all functionality of the control on the heater is
disabled. The heater functions can be controlled only
at the RS unit.
To temporarily use the heater controls, press
the MENU button. The message "JANDY REMOTE
ONLINE PUSH MENU TO DISABLE" will disappear
from the heater display. All functionality has now been
returned to the control on the heater. In this mode the
RS unit is no longer controlling the heater.
To return the functionality to the RS unit, cycle
(turn off and then turn on) the power to the heater, or
press the MENU button for 5 seconds to enter the User
Setup Mode and then enable the Jandy Remote.
6.5.3 Connection to a Secondary Use
Interface
The LXi pool/spa heater can also be controlled
remotely by installing a second wall mountable User
Interface. Please order Jandy part number R0467500.
This kit contains the second User Interface, wall
mounting backplate, and necessary hardware.

Section 7. Operating Instructions

7.1

Normal Operation

The LXi heater is capable of automatic opera-
tion based on a call for heat at preset temperatures and
an operator selection between pool or spa settings.
Additionally, the heater may be controlled by a remote
unit to anticipate bather load, changes in temperature
settings, or a variety of other demands that might be
encountered. The heater has an internal safety system
which allows operation in a variety of conditions and
prevents operation when certain adverse conditions are
encountered. The heater is capable of diagnosing prob-
lems within the safety controls scheme, enabling faster
service and less down time in the event of a failure.
When the heater is powered, water is fl owing
through the heater, and the temperature of the water
entering the heater is below the temperature control
setting, an operating cycle is initiated by the auto-
matic control. The combustion blower is started. If the
blower pressure switch senses adequate airfl ow, the ig-
nition sequence starts. First, a fi fteen second pre-purge
takes place. Next, the igniter is energized. After 40
seconds of igniter heat-up time the gas valve is opened
(approximately one minute after the call for heat). If
fl ame is sensed at the burner within seven seconds,
operation continues. Operation will continue until the
temperature of the water entering the heater reaches
the temperature control setting.
If ignition is unsuccessful, or if the fl ame fails
during normal operation, the ignition control shuts off
the gas valve. It imposes a post purge, initiates ad-
ditional ignition cycles, and shuts down the system if
ignition is not achieved in three cycles. After one hour,
the system will restart and try again.
To reset the LXi heater to provide three (3) ad-
ditional attempts without waiting an hour, turn off the
control and then put it back in either the Pool or Spa
mode.
