double swicth coolant sender

[Takid455]

looking for a temp sender that has a double switch built in and each switch is set at a different temp say 195 and 220. does such a thing exist.

why am I looking for this?

I have a twin fan set up (spal). I want both fans to have a low and high. I spoke with dakota digital regarding their PAC-2700 and received veigh answers. they said it could work if I wired both fans together. OK no problem. I asked how they monitored the current. they said they did not and I needed a 2 speed fan. I thought by lowing the current (adding a resistor), I could lower fan speed. Anyone have any inputs?

I believe Spal has a controller that will do two fans and high and low as well. Yelcamino from this site just did what you are trying. I think it was with the Spal controller. I know it was not done with Dak. Dig.'s unit. PM him to be sure.
