Model LD Pool and Spa Heater
Figure 15. Time Clock Wiring.
1. Remove heater door.
2. Remove the factory installed wire between
terminals 1 and 2 on the terminal strip (see Figure
15).
3. Connect the wires from the time clock auxiliary
switch to the two terminals. Use American Wire
Gage (AWG) No. 14 gauge stranded copper
wire with a temperature rating of 221°F (105°C)
or greater.
The length of the wire between the heater and
the time clock should not exceed 10-15 feet (4.57 m).
The contact points of the time clock switch should be
silver, or a low resistance alloy.

6.4 Remote Operation

The Lite2 pool/spa heater controls can be wired
for remote operation. The Jandy AquaLink
remote control permits switching from pool to spa, with
temperature set points for each, and turning the heater
on and off from a remote location. Contact your local
Jandy distributor for information on the AquaLink RS
control system to fit your back yard recreational
needs.
An interrupt (on/off) type remote can be con-
nected by removing the jumper wire on the terminal
block located in the control compartment (see Fig-
ure 6) and connecting the two wires from the remote
to the two terminals on the terminal block. This type of
remote control will turn the heater on or off, but will
not switch between the two temperature controllers on
the temperature control panel or allow for temperature
adjustments.
To connect a 3-position remote switch (not
supplied by Jandy) to a Lite2 LD heater, order a wire
harness assembly (Jandy part No. E0120000) which
connects to the temperature control panel. Installation
instructions are included with the wire harness assem-
bly. This type of remote will allow switching between
the "POOL", "SPA", and "OFF" function of the control
but does not allow for temperature adjustments.
Consult with the Jandy Service Department with
questions about installing remotes other than Jandy
brand remotes.

Operating Instructions

7.1 Normal Operation
The Lite2 model LD heater is capable of auto-
matic operation based on a call for heat at a preset
temperature. The heater has an internal safety system
which allows operation in a variety of conditions and
prevents operation when certain adverse conditions
are encountered.
When the heater's transformer is provided with a
120 VAC or 240 VAC supply, it in turn provides a 24
VAC signal to the safety circuit. When water is
flowing 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
automatic control. The temperature control circuit is
closed, activating the gas valve and the gas valve is
opened. Gas flows through the burners, is mixed with
air in the combustion chamber, and is ignited by the hot
surface igniter which is energized by the ignition
control. Operation will continue until the temperature
of the water entering the heater reaches the tempera-
ture control setting.
If ignition is unsuccessful, or if the flame fails
during normal operation, the temperature control circuit
opens and shuts off the gas valve.

7.2 Start-Up

Do not use this heater if any part has been under
water. Immediately call a qualified service technician
to inspect the heater and replace any part of the
control system and any gas control which has been
