hi all,

I am planning to replace the thermostat on my tintop syncro 2.1 WBX. I will
get an 80° thermostat.

When researching the topic on thermostats I found that some of them have a
tiny hole on it (about 1/16" diam.) and some of them don't have.

Is there a pro and con idea of having one with the 1/16" hole - or even
drill one hole?

thanks for your help,

dan
