VisionPro IAQ Thermostat

I have a IAQ tstat connected to a new YP9C modulating furnace. In the setup for the tstat it ask how many stages the furnace has. How do I answer this with it being a modulating furnace. Also the IAQ is asking about the cycles per hour to set each stage. I have went to the dealer about this, but when he set it up the first time, he just set it up using the letter E. Thanks for the help...

The IAQ can't control the modulation of your furnace. So set the IAQ to 1 heat. York says to set the CPH to 6. I find they tend to work better set to 3.

i installed one of these today and set to 4 cycles per hour simply because of the houses size and age.
