I have read in another thread about changing heat settings on the Englander 25 pdvc/55shp10. Mine is new this year manufacture date 05/2012. This morning I woke up to 58 degree's in the house and 20 degree's outside. I normally had no issues at above 30 degrees at setting 1. I had it at setting 3 last night. I believe i was told setting A is the hottest. Setting D being coolest setting. Also If my old age memory doesn't fail me, you have to unplug the stove when its cold and shut down. The replug it in and quickly touch the blower up and down buttons together until the letter shows on the heat side which is when u can change the setting up or down on the heat side. then hit on. Can any one confirm this process? also the 3 buttons on the bottom, will they need to be adjusted. Thanks and happy pelleting.
