I want to use this to control 12v relay for cooling fan on vehicle. Does it hold settings when turned off and remember settings when power reapplied?

I was never able to figure out how to set it, the instructions are written by someone not of this century or galaxy. I was going to us it for the same thing but decided to hard wire the fans to run when ever the car is on. I used it on my Hybrid batteries and got good results. good luck

Yes it does, even when supply voltage is removed. Also, it does have a SPDT relay built in. Just a reminder, it will only display in Celsius, but that is an easy conversion.

Yes it does remember the settings. The sensor wire is only like ten feet, but you can add wire to make it longer. And also the temp reads in Celsius and cannot be changed to farenheit. The sensor has to be carefully mounted. Otherwise the circuit will be closed most of the time. You should consider wiring the relay to a key-on only source and add a on-off switch inside you vehicle and it will work just as good. The relay will only close when the key is on. This product will work also if money is not an issue. Hope this helps

I use it with a cooling fan for electronic equipment in a motor home. It can be easily wired to thermostatically control any 110 volt electrical device.

It should switch automatically based on your set temp. If it needs to cool down it will switch to cool and vice versa.

Not sure....I don't like using variable on fan motors...it tends to give them a short life span....the two speeds are adequate, however I always have it set to high speed.

I believe the default can be set to what it was last turned off too. However if you leave it on and it has an ignition source as in, if you turn the key to battery then it engages the monitor or relay it will turn on without having to push power. Hope this helps.

This is a remotely operated switch. Rated for 15 amps. I use it to operate a relay and depend on the vehicle battery for power. Only power here is the battery in the remote to send the signal. It could be used to switch directly if the load was less than 15 amps. I personally would not trust it to hold up in switching a 15 amp load often and depend on a stout relay.

I am not an electrician but YES it for use in 12v systems as in a car. It is a timer relay that is in a low amp circuit to switch on and off the voltage to what ever needs the power. I am using mine to switch off and on a 12v low amp very small fan to keep air flowing over a PMD(Fuel supply Driver) in a diesel truck that is subject to over heating when engine is shut off. Check the amount of amperage that what ever circuit you are hooking it up to to see if it exceeds 5 amps. There are no instructions with it but I found out how to wire it by doing a google search. That took some time and head scratching.

The controller is a adjustable unit. You just dial back on the voltage for that particular fan until it's like 0.0 but most fans usually require more than 5V to operate at all so anything below will most likely shut them down.

It turns itself off if you remove the pan probably with the E/O message showing, but I think the off/on switch will continue to blink and the cooling fan runs awhile and then turns itself off. It does have a timer which I have not yet used.

No, This relay is for something like glow plugs on a diesel or any thing else you want to run for a set period when you apply power.

I have found that the unit will automatically restart, but it will not save your settings. You will need to re-program F/C and the temperature after a power interruption. I have been pretty happy with our unit thus far. -DA

I'm not real sure you can set it at a particular degree and leave it. I think It needs to be switched to cool or heat. There isn't an auto option on modes, only for the fan. You may want to check with them directly, as I've only had it for about week. Hope this helps....

it does keep some power in it to keep your settings but instead of reaching up and turning it on and off I have it setup so when I plug it into the cigarette lighter it turns on and when I unplug it it turns off you can also set it up to turn on and off with motion. if it had a battery it would just stay on all the time. which would fill up your memory card really fast. I'm a truck driver and I haven't let it get all that hot in my truck yet so I couldn't tell you about the durability in the heat but it seems like it would do pretty good.

I got it because it was an easy way to turn cooling fans on and off automatically. My old receiver had switched power outlets in back, but I need something smaller and the new one doesn't. This was the easiest and least expensive way to control the fans. Since it has more than one plug controlled, I plugged my two subwoofer amps into it. They don't use a lot at idle. I can't say how much power savings I'm getting, but that was not the primary reason that I this.

This Device allows control of heat, cool, off or hold settings or switch temperature readings at the device or thermostat or of course set the temperature desired. It also displays the out door temperature as I have it set up. Depending on the system I understand it may have more capabilities but I do not see any fan controls available on the device.

This is a relay. The relay is powered by 120VAC, but the contacts of the switch are completely isolated from that 120 VAC, so that you may run almost anything off it, including low voltage devices. I use several of these to control low voltage devices and it works fine.

Yes. When you manually press the fan button on the switch, it will behave like a timer switch shutting off after 30 minutes.
