Got a Prestige IAQ in my house. set up for 2 heat/1 cool. Have tried almost every combination possible in the installer set up but whenever I turn the heat up enough to kick in second stage it'll always kick back down to low fire a couple degrees shy of setpoint (like it's supposed to) But then it kicks the furnace off and says "waiting for equipment" and then turns back on about 60 seconds later.
What gives? Previous VP 8320 did this too, not nearly as often as the Prestige though (once in a blue moon). Can't imagine what the thermostat thinks it's doing by short cycling the furnace in the middle of bringing the temp up.
