Fleetwood Discovery AC/Heat Zones

[ww1wxradio]

Just purchased a 2015 Discovery 40E and having issues figuring out these zones for heat and ac. Zone 1 appears to have the sensor on the side of the cabinet over the driver's seat. This sensor needs to be moved because when that side of the coach is in the sun it will read 95 on the thermostat due to the heat reflection inside the coach.

Zone 2 appears to have it's sensor on the wall by the half bath.

Zone 3 sensor is in the bedroom by the sliding door.

The heat zones are 1 and 2 for gas and electric and I assume electric is heat pump.

Zone 3 will say heat but not adjustable.

Zone 1 in AC mode is front of coach . . . Zone 2 in AC mode is middle coach . . . Zone 3 in AC mode is bedroom.



So if you have the bedroom furnace which I believe is zone 2 for heat it will not heat properly if the bedroom door is closed because the sensor is by the half bath and sensing what the temperature is in the middle of the coach and NOT the bedroom.

Am I correct in assuming this and how can this be corrected???

So upon further investigation I think I can correct this problem by putting my gas furnace in the bedroom on Zone 3 so the furnace operates properly with the remote sensor in the bedroom.

I believe I will need to move the wire from Heat 2 on the thermostat to Heat 3 and re-program the thermostat so the gas furnace shows up on Zone 3.

Any Guru's out there enlighten me on this???

I'm in the same boat as you. I dont understand why they put temp sensor in kitchen area for zone 2 and not in the bathroom. My 2 gas furnaces are wired to Zone 1 and 2 from mfgr. There is no heat setting for zone 3 (but zone 2 gas furnace has ducts into back bedroom and bath). If we leave doors open it works ok but closed it gets too cold.

I had thought about switching rear gas furnace to use Zone 3 temp sensor in bedroom, but did not know if that is changed at the thermostat, or in the load shed panels about the drivers seat.

Let me know what you figure out as I would love to change mine as well....

I had my rv at the house for maintenance so I went ahead and tried this out on my rig. It worked as you mentioned in your post. I pulled thermostat and disconnected from factory harness side. On factory harness 9 pin square connector, i moved the blue/white wire from pin 7 to pin 8. I used a small phillips screwdriver to push terminal out carefully, and reinsert into middle hole pin 8. Look under lav sink at gas furnace and verify the color of signal wire going into it. Mine was blue/white. (Plus larger red/black power/ground)

To change thermostat press and hold up/down buttons till display blinks. Change to zone 2 annd use mode to change that to only cool. Then zone 3 set to cool/heat/gas furnace. To save slide power button to heat then back to off. Your zone 3 should now call for heat when bedroom temps call for it.

Probably should Turn off all the power in rig prior to making changes..
