Here is a screen shot of the data that I log on my OWB:
I am using a LabJack U12 data interface and DaqFactory software. Stove is a Hardy H2 with a 2 stage Ranco temperature controller, set up to operate as follows:
Damper opens if the temp gets below 155, closes at 160. If the damper can't keep up the fan comes on a 145 and turns of at 155 and the damper stays open until 160. This mode of operation seems to save on wood by not running the fan unless you really need it.
The current graph reflects the stove being loaded with beetle eaten pine, day time temperatures in the 50's and night time temps in the 30's.
Potential future enhancements include:
Connecting the Fan / Damper / Pump / Fill inputs (already on the screen)
Outside air temperature
Stack Temperature
Stack Opacity
Designing a robotic loader to fill the stove
