I have a Heart & Home Tech. Smart-Batt II that does not seem to be functioning properly, that is I can't seem to match security code, as per instructions therefore the stove will not start unless I overide. Does anyone here have the same unit and am I just missing something. As per instructions I move the indicator to remote on the reciever and push the learn button I do hear one beep from receiver as it should, but when I press the Mode button as instructed I do not hear several beeps and the units do not talk to each other, I have tried this a number of times..........HELP and Thanks11
