Question

Lost outside temperature reading. Removed batteries from clock and outside sensor and waited 30 min. When batteries were installed temperature and clock functioned properly. However we keep losing the outside reading.We repeated the sequence and always get the same results. What am I doing wrongMy outdoor transmitter started reading 100+ degrees......I check the batteries - almost dead....replaced them per the procedure...same problem...there is a tuning capacitor inside that I think changes the 433mhz frequency, that will allow to "calibrate" the thermistor so that the correct temperature can be displayed...it does indeed change the reading, but it never changes the reading, like when I 'warm' it up. Anyone have some ideas? TY - RepoMan :^)|
