** Caution: EXTERNAL Sender ** A few years ago, when in Germany, I bought a domestic digital indoor/outdoor thermometer. It looked as though it was made for the international market and had a C/F switch. I did a series of test and came to the conclusion that it had a 10-bit ADC with one bit equal to 0.1 degree Celsius. The Fahrenheit display was a conversion of the Celsius display. The give-away? The Celsius display ramped up in 0,1 degree increments while the Fahrenheit display ramped up in a series of five 0.2 degree steps followed by a 0'1 degree step.

I told him I don't use Fahrenheit. He said he's seen a fair number of thermostats set to Celsius. How common is it for thermostats in the USA to display in Celsius? The symptom was the same as the last time he came out: the fan motor was quivering instead of turning. The cause, though, was different. Last time he had to replace the whole fan/motor assembly because the windings were broken. This time it was just a faulty capacitor. Pierre -- When a barnacle settles down, its brain disintegrates.
