I have a 2011 Dutchman Voltage. Tonight I pulled into a campground in Florida, got all set up, and went to start up the A/C. The thermostat said E1, tried to clear the code, now the thermostat only shows zone 1 & 4, but only a 2 zone system, and still no A/C. Also, the inside/outside temps show 0* F & -18*C. I guarantee it's closer to 100* F in here --- HELP!!!!

You will need to take the inside cover down on the front air conditioner. There is a control box mounted there, open the control box and you should see many dip switches on the face of the board. Make sure that Zone 1 and Zone 2 are selected (furnace as well if your furnace is fed through this thermostat). After making sure that the switches are set, turn off the thermostat and hold down the mode and zone buttons at the same time, turn the tstat back on. When EE appears on the face, release the buttons and see if everything works. If not, then I would say that you have a bad control unit in the air conditioner.

Yes the 10% factor is correct. Anything greater than ten 10% will affect operation without question.

Sounds like you have dirty condenser coils. Remove the upper shroud and check the condenser for clean. Take a water hose and gently spray out the coils paying special attention not to bend the coils over with too much pressure. This will allow more air movement through the coils and give you better cooling efficiency.

Hope this helps,

In the main unit, remove the inner shroud and then pull down the control unit (two phillips screws). Remove the access cover on the control box to view the dip switches. The switches should be set to Zone 1 and Zone 2 to on and then the furnace to on (if so equipped). If the zones are not in the in position, then set them to the correct position and reset the thermostat again. If they are correct, try turning them off, resetting the thermostat and then turning them back on and resetting again. If this does not work, then you have a bad thermostat or control box.

Hope this helps,

This appears to be a low charge. you should see a 15-20 degree split between the discharge venting and the return air venting.
