Track furnace on time

[cadillackid]

I use the HVAC monitor device i got from hobby boards... and then I just backprobed the terminals on the gas valve of the furnace and for the compressor lead on the A/C...


now this will all get a huge amount tougher once I get my fully variable speed compressor heatpump system installed....

I have modified a DS10A and added a circuit that detects 24V. I have 3 of them on each HVAC unit. A script stores the data in MySQL. I use chardirector and asp to plot the results. www.chezmurphy.net -> hvac activity.

Daniel,

Looks very good, Are you willing to share your scripts and ASP code?
