Okay to remove all confusion about the operation of the LM-311 and got the following results:
**thermistor cold**
pin2 (V+) = 1.51v (low)
pin3 (V-) = 1.79v (High)
pin7(Output) = 0.10v (Low)
**thermistor hot**
pin2 (V+) = 3.74v (High)
pin3 (V-) = 1.79v (Low)
pin7(Output) = 4.43v (High)
Obviously when it was hot it started cooling down and the values kept going down slowly to their previous numbers.
So assuming it works this way then we have to program the 08M so that when In4 = 1 and In3 = 1 Out2 = 1 (after 12s).
