The HSI 2 ignition control has an initial ignitor warmup time of 7 seconds In the event of a retry the warmup time will be increased by two seconds and that duration will remain effective until another retry In which case the warmup time is again increased by two seconds but never more than 11 seconds At the end of the heat cycle the warmup time is reset back to the minimum time setting NOTE The White Rodgers 50M61 and 50V61 ignition con trols have an ignitor warmup time of 20 seconds These con trols have a built in learning routine that gradually reduces the ON time of the ignitor The effect is that the ignitor operates at a cooler temperature The learning routine will eventually reduce the ignitor ON time to a point at which the ignitor is too cold to ignite the gas The control will then increase the ON time and initiate an ignition retry The furnace will light The control will remain at this point for 256 thermostat cycles after which it will re enter the learning routine IMPORTANT The ONLY way to determine if the ignitor ON time is changing is to view the ignitor voltage wave form with an oscilloscope 6 Ifproofofflame was established voltage will be provided to the air circulation blower following the heat on delay period 152 a Checkfor 120 volts from the CIR terminal WH wire on GUIA GCIA GUIC GCIC GUID GUCA GUIE GCCA GCLA GULA and GUSA models or WH 33 wire on GUIS and GCIS m
