Thanks Larry, very interesting info. If the sensor in mine also turns
out to be a thermistor (a likelihood) it really simplifies tweaking.
In the case of your figures, you could fool the thermostat into
thinking it was 98 when it was actually 82 by shunting the thermistor
with 42,900 ohms. Since the range of actual thermistor values over
real room temperatures would be fairly narrow, something along these
lines would probably be safe (only down side is the temp readout would
be wrong, but since it is anyway (says 60 when it's 69) no loss
there). Also very easy/cheap to implement.

Hi Dan...

With all this great info, seems you can't go wrong!

Another suggestion might be to consider using perhaps a 100k
variable rather than a fixed resistor.

A bit of tweaking might let you make the readout "wrong" by
10 degrees F, so that for instance you could more understandably
have 65 degrees read 75, etc.

Take care.

I agree a pot is the way to go, after calculating a ballpark figure.

Thanks!
