I have a Chronotherm IV tstat and continue to blow circuit board fuses. I followed the wiring diagram that was provided... there are two transformer circuits and the heating is running fine. Cannot get the stat to work. I have jumpered both fan and condenser circuits and got them both to work.
What is the likelihood of a bad stat. thoughts on which color wires should land on the o,g,y,r terminals... curently o =w,g=g,y=y and r=r...
Help we are hot and do not want to jumper past the tstat for a long time... Stuck in Bill's tropical humidity in the Northeast...
