My
guess is that people outside of the U.S. and Canada are used to cooler temps
indoors in the winter and warmer ones in the summer as the cost of heating and
cooling is greater and therefore, the differences are not really
noticeable. Sometimes, especially with digital thermostats, clicking the
heat up a degree (F or C) is enough to cycle the heat on and thus, make the
house feel warmer. I, for one, don't have a problem with the magnitude of
change in 1 degree C. My thermostat is set for 21 degrees during the day and 17
at night ( I work at home). I find these temperatures to be totally
suitable for my tastes. I also have not received any complaints from
visitors. I wonder if I will feel the same way in a couple of weeks when
my windows are replaced.

Subject: [USMA:27942] Re: Residential thermostatsFrom the Honeywell website is the following excerpt:Why is it important to have accuracy within 1�?
Most people sense a temperature change around 1.8�. Honeywell thermostats are more accurate than some electronic thermostats which can vary up to 9�. Most thermostat manufacturers use some of our thermostat technology - none are as accurate as Honeywell.The 1.8� is 1.8�F. Note that this is EXACTLY 1.0�C. Someone must have done research and found that the human body can only distinguish a 1�C change. Thus a 1�F resolution or "accuracy" is ficticious.I wonder if people in metric countries rely on thermometers as much as people in the US do. Maybe with people in metric countries using the same system as their body's own thermostat and can get a more accurate idea as to the ambient temperature without the use of a thermometer. Fahrenheit is out of sync with the human body and thus using the body to obtain a Fahreheit temperature is almost impossible, thus the need for thermometers.Euric----- Original Message -----From: "Ma Be" <[EMAIL PROTECTED]>To: "U.S. Metric Association" <[EMAIL PROTECTED]>Sent: Tuesday, 2003-12-23 16:23Subject: [USMA:27941] Re: Residential thermostats> 'Most certainly noticeable'??? Hmm... I'm sorry, Norm, but I don't think so! At least I can't tell, even between say 17 or 18 degrees.

It may be because there are 9 0F to each 5 0C. Thus if one wants to change it up or down, usually one has to punch the up or down arrows twice. This may be because at most times 1 0C is equal to 2 0F (or you could say that usually each punch equals aproximately 0.5 0C.
