Vacation timer for feeding rotifeast, phytofeast, etc

[Thales]

I want the variable.
It pulls air out of the tank area to the outside. I would like it to pull all the time, but pull more when the tank gets hot, or when the MH heat the air around the tank.

I may just save up for the one Gresham posted.

FYI, I just bought a new timer switch for another tank I am putting together and I ended up buying a manual one from HD that I have never used before. Low and behold, if has the function you are looking for. They lable this switch function as SPDT, "Reverse Action Switching."

The box on the outside does not say that it has this function in any way (no wonder I could never find it), I only found it because I was looking at the connections and found load 1 and load 2 written on it. I had to read the instructions to see what they where and found that it did the function you were looking for.

They sell them at HomeDepot

Here is a web page for it

Gresham, next time you don't need to buy a relay, you owe me a beer

Now I have to go redesign my electrical board.

Well, I opened my second one and that one was missing the terminal to make the reverse switching work. I guess my first one was just in the wrong box. At least it exists. Look for SPDT on the box if you choose to get one of these.

Makes total sense since SPDT means Single pole, double throw.

Whats the duration? The website says 2 hours, true?

2, 4, 6, 12 hours. You can set it for less of course. You should be able to take them apart as well, needs one of those star screw drivers.
