Specific question regarding power cables

[HeartCore]

Right, not sure where this topic should go but since I need to info to finish my canna growing room I put it here.

I have this ventilation system that I will use for two purposes, refreshing the air and lowering the temps.

For refreshing the air, I have a timer. For lowering the temp, I have a temperature controlled switch. What I want to do is that, regardless of the timer, once the temp in my growing room is too high, it should start up the ventilation system.

What I have in mind is using connectorthingies (kroonstenen lol), I want to double the cables coming from the vent. So I will end with four instead of two. One pair I want to connect to the timer, the other pair to the temp switch, this way both switched can control the vent regardless of eachother.

Would this be a problem? Is this a dangerous construction when for example, both switches give power? I am a noob concerning power issues

Thanks
HC

As far as I can remember my Electricity Classes in school it can be done like you said it. Just make sure your switches are parallel to each other and come from the same power source. In that way there is no possibility of overload. Since the switches don't "give power" as you said it, but just turn it on or off, you just need to make sure that the powersource is the right voltage. For example if the vent needs 16V, you need an adapter (probably sold together with the vent). The switches should then come in between.

Again, I haven't thought about electricity at all the last 7 years or so, but I guess this would be it. Others please comment.

Hee Fork,

Thanks, perfectly convinced after your reply!

Ventilation system is now up and running!

yea that's the same way I have mine set up...just make sure that you use the same plug on your wall for each fan, that way you know your pulling power from the same circut.

Working perfectly now....Ony one thing, it seems my timer clock is lagging almost an hour per day.Probably a bad clock, will replace this week.

Why don't you just ventilate 24/7? The vent won't eat up that much energy (compared to the lights...) and the plants will grow better if they got ventilation all the time. The more airstream around the leaves the more CO2 they'll be able to consume.

Changed the plan. I'm venting constantly now through a dimmer on low. Second power cable is linked through a second dimmer and is switched by a thermostate. This way there is constant airflow on low speed and it will go on high when temps are too hot.
