[USMA:27929] RE: Residential thermostats

[Carleton MacDonald]

My Honeywell thermostat doesn’t have this requirement.  Set it to Celsius and program it normally, in increments of one degree.   cm   -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]On Behalf Of Norman & Nancy Werling Sent: Monday, December 22, 2003 20:24 To: U.S. Metric Association Cc: Gregory W. Peterson Subject: [USMA:27927] Residential thermostats       My White-Rodgers programable thermostat instructs me to program it in Fahrenheit before switching it over to Celsius.  I may understand why that is required.  It may be because there are 9 �F to each 5 �C.  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 �C is equal to 2 �F (or you could say that usually each punch equals aproximately 0.5 �C.    I have to insist that, to me, changing by 1 �F in the house is very truly and most certainly noticeable.  This leads me to think that thermostats designed for Celsius may need to be calibrated in 0.5 �C increments.  What is done in Europe?    Norm
