Hi
I have one of the velleman thermostat kits.

http://www.quasarelectronics.com/vmk138.htm

The kit works well but i'm trying to improve the hysterisis so it tightens up from 1 Celcius.

I've changed one of the resistors which contol hysterisis from 6m to 10m which might have helped a bit, anyone get any other ideas of how I could do this?


Cheers
