Page 5ENGLISHJandy ® Pro Series, JXi ™ Gas-Fired Pool & Spa Heater | Installation & Operation ManualNOTE: If the heater is installed below the level of the pool,(ormore than two feet above the pool level), the pressureswitch setting must be adjusted. See Section 5.4Adjusting the Water Pressure Switch for guidelines.Water Temperature ControlAll heater models are equipped with an electronic controlwhich senses water temperature by means of a thermistorand controls heater operation to bring the water to thetemperature selected. It has an option for two (2) separatethermostat settings which are typically used to set pool andspa temperatures.Ignition ControlThe ignition control provides energy for ignition of the air/gas mixture, monitors the flame and controls the gas valve.When the temperature control calls for heat, the ignitioncontrol initiates the start-up process by first purging thecombustion chamber gases. The ignition control willthen energize the igniter and open the gas valve whenthe igniter surface is sufficiently hot. During the start-upprocess and after ignition, the ignition control system iscontinually monitoring the flame condition. If the controlsenses an unstable flame it will close the gas valve as asafety precaution.Section 2.
