Numbers flashing or counting down on Smartstat TH115 PB112. Continuously booting up.


I have numbers flashing repeatedly in a loop on my Smartstat TH115 PB112.  It is continually booting up.

Try cycling the power of the stat.  If the numbers are still flashing, the unit will need to be replaced.  No need to do ohms testing, as the problem is in the thermostat.
