Okay, I bypassed the safety shutoffs on the furnace and measured the "24VAC" there: 28VAC according to my (non-RMS) meter.

Edit: It was probably designed to output 24VAC minimum at 110VAC input, all at 60.000HZ. But here in Ottawa, the line voltage is usually between 120VAC and 125VAC -- currently showing 123VAC on my (non-RMS) meter.

Cheers
