I have a 105 and am experiencing the same problem

Customer Question

Tim, I have a 105 and am experiencing the same problem intermittently. I follower inst to unlock board and when I get to ERROR, I step thru a 1 thru 6 sequence with data for each step. Quest is how do I determine when lock out occured. Data set is (1 : 03), (2 : 02), (3 : 118 fyi set point for heating is 130), (4 : 114), (5 : -22), (6 : -22). I do have a amtrol tank, but do not know it was demanding at the time of the lock out. Thank you in advance for your help.
