do you need a thermastat, or does it just run when the suns out and shuts off when the suns not?and does it run when its partly cloudy?

You must get a thermastat. It doesn't run constantly, but work based on the temperature in the attic. It runs, but barely on cloudy days. It has to be sunny. I guess that's the trade off when you get a solar fan, but it runs for free.

You do not need a thermostat. When the attic reaches a certain temperature, it comes on automatically. Otherwise, it stays off. It immediately began working as soon as it was installed.

You don't need the thermostat and it runs when the sun is out. It does not run when there is no sun and runs slowly when there are clouds unless they are very heavy.

Buy the recommended thermostat. It will automatically turn on and off as needed. If you don't then yes it will run whenever light is present. It will run when it's partly cloudy. You can also wire in a thermostat and set the temperature for what you want. I didn't and mine works great. Highly recommend it. I think the thermostat is 12 bucks. Buy it I did and don't regret it. Have a great day.

I use a plug in programmable thermostat to control when the unit turns on and off as well as the room temp to be maintained while on. As some one stated as long as it is UV listed you should be okay.

I purchased this in spring and installed it on the north face of my house which only gets direct sun briefly on summer evenings. It began working the same day it was installed. The solar collector is on top

I was told by the contractor who installed it for me that yes it would need sunlight to run. Side note: we've noticed a substantial difference in our house temperature. Which has in turn saved us money on our power bill. Hope that helps.

It will automatically cycle between heating and cooling modes. If you hit the heat threshold, it will call for heat. If you hit the cool threshold, it will call for cool. It doesn't have a heat or cool mode - it's full auto.

you have 2 screens one for fan to set it to on or auto. The other for heat or cool. Set either one to a temp that will make sure it won't come on and the fan to on and it will run continuously.

It has a thermostat. It goes on and off depending on the ambient temperature.

Yes.I purchased the thermostat.I to live in fla.the unit runs all day in the summertime. The thermostat gets used in the other seasons when it's not so hot.

The fan should not run continuously. If the evap. Thermostat is satisfied with the room temperature the whole unit should stop running. Make sure your setting is not on DRY.

There is a thermostat, so you can set it to a certain temp, and it will shut off automatically. Other then that no, it will run constantly if the temp is set to high. It uses very little energy though.

I'm taking a big gamble and have boughten 2 of these 60 watt systems to power up a remote cabin in upstate new york.Mostly lighting and a 12 volt water pump.Very conservative use.Lights will only be on where I need them.My questions are:will a cloud covered winter sky still produce a trickle charge from these panels?We can go weeks without a sunny day.I also will have to keep the snow and ice off the panels.Should I set up two completely seperate systems or should I tie both together on one battery bank?Can I also hook a regular battery charger to the batteries in conjunction with the solar chargers?

It starts when the temp hits the set temp. If the unit is set @ 70 for the winter, the unit will not cycle on until it drops below 70. In the summer if you want it at 68 the units kicks on at 69. It is not a "smart" device but you can set presets for the week and week end. I've had my unit for about 5 years. It has worked well and was about $50.

This turns itself off when the water runs out so it doesn't run the heating element when there is no water to evaporate. This is a good thing. Nothing to be worried about. I find that a full tank of water lasts one whole night on the high setting (avg. 8 to 9 hrs.) and on the low setting will use only about 2/3 of the tank. You might try the low setting if it really bothers you that it turns itself off. Hope this helps!

When the sun is not out, you need to stop water from going through the heaters. It will do the opposite if the sun is not out and cool the water. Hope this helps.

I can't answer that directly. I've had mine in for less than a month. I can tell you that it's not necessary to have it on all the time. I programmed mine to run constantly in the mornings and evenings when the water gets heavy use in our house. For the time in between I have set it to go on and off every 15 minutes. I work from home and use the water fairly often at those times. I have noticed no real difference than when it's running full time at peak hours. There is also no reason to have it running in the middle of the night. I look at it more from a longevity of the pump perspective than an energy perspective. I don't think they use that much energy to run, but the pump (any pump) has a life span. The only reason I may run mine at night is for winter. The farthest pipes from the water heater are on an outside wall. A well-insulated outside wall, but if we get sub-zero temps like we did last year I may run every half hour or so at night just to keep the pipe warm.

I run it in a drag race car with no thermostat. If you are running it in a street car I would recommend running a thermostat.

Make sure you have the unit set on the little screen with the sun pattern , that meens its in cool mode .f its in dehumudify mode,the little droplets pattern will show up on the small screen , you wont get much cooling when its on that cycle ...Thats done by using the MODE button . I found this out that same way , room wasnt getting very cool in dehumidifiing mode , , ...I had to go over the directions to get the modes down properly ...
