Acronyms GND = Ground IGN = <strong>Ignition</strong> LP = Liquid Propane MV = Main Valve NO = Normally Open NC = Normally Closed PV = Pilot Valve V AC = Voltage Alternating Current V DC = Voltage Direct Current
Definitions Sensors - Senses the variable change in temperature and sendsa signal to the controller. Transmitters - Interprets signal from sensor to displaycondition of temperature variable. Transformer - An electromagnetic device that either raises orlowers the voltage of an alternating current electrical system. Voltage - The electrical potential pressure behind the flow ofelectricity, measured in terms of Volts. Current - The movement of an electrical charge through acircuit, measured in terms of Amps. Hertz - A unit of measurement for frequency in cycles persecond of a waveform. Relay - An electromechanical device that opens or closescontacts when a current is passed through a coil.
