Our local power company is moving to a peak metering scheme for setting consumer billing rates. Customers will be billed on a combination of 1) their overall monthly usage (kW-hr), and 2) their peak load during the billing cycle.

Our house has two roof-mounted A/C units with separate thermostats and these together are the main use of electricity. If both units were to start/run at the same time it greatly exaggerates the peak electrical load and will jack up our bills.

Are there any working & debugged methods (we already have a ISY control for lighting) to sequence the two A/C units so that only one can start and run at the same time?

Be sure to also ask on the ISY forum. That's where you'll find a lot of folks using more advanced conditional logic programming to handle challenges like time-of-use metering, automatic setback via presence detection and more.
