The bedroom fan should only close when the lever on the thermostat is fully down in the "Off" position. When it is up on a particular temperature, the fan will cycle on and off, and the top will stay open when cycled off. Whether cycled on or off, it will close when drops of rain hit the sensor.
I have 2 fantastic fans on my rig, the are the newer design as the rig is 2003. I love them, in manual mode I can open the top just until the fan starts blowing and can use it in the rain. It has to be blowing out and at highest speed. On of the Fantastic dealers showed me this trick and it works well. Also, if you have a problem with a Fantastic fan they are excellent about fixing them. Some one??? backed the trailer under the car port with the fantastic fan open and broke the cover. I called and orderd and new one and they sent it free. Now that is service. If you are at a rally and the dealers are there, they can check out to operation of your fan.
I rarely use the temperature setting as I prefer to do it manually so I can't help on the temperture setting questions.
Ahhhsooo!!! I believe Maurice and Brett G. have solved the mystery! I was relating the "turning off" of the bedroom thermostat (---by sliding the lever down) as being typical of the normal operation of the unit when set at any given temperature. Per Brett G. the front unit, with the integral thermostat, functions in the same manner. Hereinafter I promise to setem and forgetem!
I've set my front one during mild weather so that it cycles on and off in the 65-70 degree temperature range. It's nice to have them run constantly during the day above 70 degrees, yet shut off when it cools below about 65 degrees at night.
If the fan noise bothers you while sleeping, you can open the bedroom vent with the In/Out switch in the middle position to keep the motor from running, and just the fan in the living room. OTOH, if the fan noise HELPS you sleep, you can do the opposite.
RoadKingMoe, do you have a vent with a light around it in the front of your A/S. if so how do you control it.
i have a fantastic in the stateroom and this other vent in the front, there is a switch to turn the light off but i can not find one for the vent itself. the cover is a square metal one not like on the fantastic. help me some one this fan runs all of the time.
I found out yesterday evening that the vent cover for the bedroom fan does cycle open and shut (---per the temperature setting) without manually moving the wall-mounted thermostat lever to the bottom. This is with the fan switch in the "automatic" position. I didn't try it with the switch in the "manual" position as my thinking last night was that this would by-pass the wall thermostat. I hope I'm wrong, since the sound of the vent motor cycling open and shut all night would drive me nuts!
i just went to the A/S and removed the light cover did not see any type of switch. so i removed the whole light from the ceiling. still can not see any type of switch on the cover like you mentioned, has any one knowledge of where this little cover actuated switch would be hiding? this fan is driving me crazy wish it was a fantastic to match the rear already.
Cracker, I'm at work now and can't take a look at the bedroom fan, but if it has a two-position switch that shows the cover open and closed, that switch should probably be in the open position for it to remain open while cycling the fan on and off.
Most Fantastic Vent fans have up a manual turn knob that you pull down on to disengage the cover and knob from the motor to manually open and close the cover. Mine has a mechanical slide mechanism next to the knob to do that. You definitely don't want to disengage the cover from the motor if you want the rain sensor to work.
