  • Thermostats garbled visual

    We have a new 310 GK. Both of the thermostats the majority of the time the readout is all garbled. Like it showing you all of the words at once and it’s hard to tell exactly where it is set. Is it typically just needing a replacement thermostat box or could there be a board issues somewhere?

    Not a common failure mode (at least to me). In addition to your list I suggest checking the +12vDC and -12vDC ("ground") connection to the thermostats. Since both are having an issue I'd be looking for something common to both units.
