I keep my motorhome parked next to the house where I can plug my rig easily to 110. The motorhome reaches 103° during the day here in Florida. My question is can I use a timer to go on and off at various times during the day just to get my fantastic fans to kick on every once in a while and suck out some of the heat? I wouldn't think that powering the RV power on and off via a timer would damage anything I want to verify that. I pigtail from 50 amp to 30 app to a 12 gauge extension cord. I want to put the extension cord on a timer to power on the RV during the day. Hope this makes sense to everyone and thank you

Hi Jim,The timers will have to be after the battery or just before the fans.

I lived in South FL for many years. I simply kept all the roof vents opened (they had covers) and put that silver insulating material on all south and west facing windows and lowered the shades on the others.Never had a problem of any type. It gets hot, but nothing seems to get hurt.

We ran 3 Fantastic fans during the summer and fall for several years while being pluged to 110 volts at the house, as long as the power is on and the fans are on you will be ok, set them at No 2 speed that's what works best.I ran a simple extention cable from the house to the RV from a wall socket in the covered patio, no fancy cables 100' orange x-tention cable from Home Despot. navegator

I just use a couple of house fans plugged into the 110. At first I set them on a timer, but I now just keep them going 24/7 to circulate the air. I leave the roof vent partially open. The fans were inexpensive and seem to do the job.

It will just keep running off of the battery. When you reconnect AC, the battery will recharge and you have saved nothing.

All of the fantastic fans are not temperature sensing. The 14 speed remote control model is. I installed ours in the kitchen so it's away from the bedroom.

Why not just plug in the MH and let the equipment you have (converter, charger, etc) do what it does to run the temp controlled fantastic fan? I kept our previous 5'er plugged in at home for 4+ years and now the MH for almost 6. The MH does have a charge wizard thing and my house battery has lasted 5 years so far.

The same people that make those little lamp timers make ones that are temperature triggered. I use a couple for various things including venting the coach. I rigged up a small battery charger that powers the FF in the roof vent via a 12 volt jack (actually an old style 1/4" headphone jack) on the fan itself in parallel with the standard wiring.

It works very well.

Does your air conditioner have a fan mode? If it does, you can set the timers for when you want it on and off plus you can set the temperature on the thermostat. My a/c units pull, at most, 9A each when starting and 7A after that. We are currently plugged into a 15A receptacle with a 15A extension cord. Runs one A/C just fine.

It would work if the battery was disconnected

One other thought- I think a lot of these fans have thermostats which do the magical trick of coming on when it's hot and turning off when it gets cool.

Just bought a house here in Florida. I have the MH plugged in 'just' because I am using the antenna from the MH to power the TV inside the house while I remodel. That said.

It's been plugged in, windows closed, with all roof vents open(they have maxxair covers) for one year now.....no ac or fan on inside and all is well! Heat naturally rises so all the hat goes out the vents.

If it were true that a fan or ac HAS to be on in RV's parked in Florida or they would be ruined........then each and every RV on a dealership lot would be not be worth selling. And they don't even open the roof vents.:W
