Several days of temperature data. The blue lines that come down from the top indicate the cooling fan is running. The lines that come up from the bottom indicate when the heater is on. I was in the process of working out the heating hystersis (sp?). Ended up at 1 degree (was 5 to start with). The heater is switched on and off more frequently but the temperature only varies by a bit over 1 degree. Sweet.
