I'm the HO. Just had a new Lennox G61MP (94% 2 stage) installed w/Aprilaire 700 humidifier and Aprilaire 8570 stat. There is also a 2-zone damper system installed to separate main floor from basement (not Lennox or Aprilaire made). I'm not sure the contractor really understands how its all supposed to work together or how to set up the stat. There is a sensor that comes with the 700 that goes from the humidastat mounted in the return plenum to the outside - which is supposed to also communicate with the 8570. Purpose is to run the fan and 700 for as little as 5 mins and as much as 15 mins. longer after heat call is satisfied in order to bring humidity level to desired level (without furnace generating heat). It's not doing that and humidity levels are too low. The other problem is I'm not sure the dip switches on the 8570 are set properly. I know what the settings are supposed to be according to the manual for my set up (gas, multi, H/C) but not sure about "6504 vs. AHC" as while I do have 2 zones, I do not have the Aprilaire 6504 zoning system. Can someone confirm the following:
1) wiring set up for this combination of equipment (into 8570)
2) proper dip settings for this combination of equipment (inside 8570)
3) anything else I should know or check to make sure combo is installed correctly.
One last problem... it appears the display on the 8570 displays current temp about 3-4 degrees above what it actaully appears to be in the room. I've checked it against a portable digital therm. defective? something else influencing it?
