Do you implement any hold time on the heating on/off state ? i.e. It can
only change 1 a minute etc. or do you rely on the general hysteresis of the
house to ensure the thermostat cant cycle on/off too quickly ?

I have working code for :- Reading the DS1820 and displaying to a 2 line
LCD
+ RS232 Comms for Parameter Setup/Temperature interogation

Which is now 99% of the available flash on a 2313 using BASCOM-AVR. Any
hints and tips for code optimisation !

Thanks
Dean
