Model LD Pool and Spa Heater Page 191. Remove heater door.2. Remove the factory installed wire betweenterminals 1 and 2 on the terminal strip (see Figure15).3. Connect the wires from the time clock auxiliaryswitch to the two terminals. Use American WireGage (AWG) No. 14 gauge stranded copperwire with a temperature rating of 221°F (105°C)or greater.The length of the wire between the heater andthe time clock should not exceed 10-15 feet (4.57 m).The contact points of the time clock switch should besilver, or a low resistance alloy.6.4 Remote OperationThe Lite2 pool/spa heater controls can be wiredfor remote operation. The Jandy AquaLink® RSremote control permits switching from pool to spa, withtemperature set points for each, and turning the heateron and off from a remote location. Contact your localJandy distributor for information on the AquaLink RScontrol system to fit your back yard recreationalneeds.An interrupt (on/off) type remote can be con-nected by removing the jumper wire on the terminalblock located in the control compartment (see Fig-ure 6) and connecting the two wires from the remoteto the two terminals on the terminal block. This type ofremote control will turn the heater on or off, but willnot switch between the two temperature controllers onthe temperature control panel or allow for temperatureadjustments.To connect a 3-position remote switch (notsupplied by Jandy) to a Lite2 LD heater, order a wireharness assembly (Jandy part No. E0120000) whichconnects to the temperature control panel. Installationinstructions are included with the wire harness assem-bly. This type of remote will allow switching betweenthe "POOL", "SPA", and "OFF" function of the controlbut does not allow for temperature adjustments.Consult with the Jandy Service Department withquestions about installing remotes other than Jandybrand remotes.SECTION 7.Operating Instructions7.1 Normal OperationThe Lite2 model LD heater is capable of auto-matic operation based on a call for heat at a presettemperature. The heater has an internal safety systemwhich allows operation in a variety of conditions andprevents operation when certain adverse conditionsare encountered.When the heater's transformer is provided with a120 VAC or 240 VAC supply, it in turn provides a 24VAC signal to the safety circuit. When water isflowing through the heater, and the temperature of thewater entering the heater is below the temperaturecontrol setting, an operating cycle is initiated by theautomatic control. The temperature control circuit isclosed, activating the gas valve and the gas valve isopened. Gas flows through the burners, is mixed withair in the combustion chamber, and is ignited by the hotsurface igniter which is energized by the ignitioncontrol. Operation will continue until the temperatureof the water entering the heater reaches the tempera-ture control setting.If ignition is unsuccessful, or if the flame failsduring normal operation, the temperature control circuitopens and shuts off the gas valve.7.2 Start-UpCAUTIONDo not use this heater if any part has been underwater. Immediately call a qualified service technicianto inspect the heater and replace any part of thecontrol system and any gas control which has beenunder water.ATTENTIONN'utilisez pas cet appareil s'il a été plongé dans l'eau,même partiellement. Faites inspecter l'appareil parun technicien qualifié et remplacez toute partie dusystème de contrôle et toute commande qui ont étéplongés dans l'eau.Figure 15. Time Clock Wiring. |
