yes Bill that is what i was implying was using a bottom and top heater. how would you go about doing a top and bottom heater via a controller.

personally I use 2 controllers, 1 for the bottom blanket, 1 for the top blanket. Unless you have a fancy "dual" controller with 2 temperature inputs and 2 controlling outputs (don't know if such a thing exists...) then you will not get accurate control on one of the blankets with a single controller setup (i.e. the blanket on the surface of which temperature is measured will work just fine... the other one will be controlled effectively open-loop and so your PID will basically not be controlling its temperature at all... it may be too hot, too cold, oscillating, etc)

Truth is, if you can cough up the dough for a second blanket (not cheap) then you probably owe it to yourself to get a second cheap controller off eBay

cheers

3 phase electricity - 380v (RST+N)...

you must divide the power by the R-T or R-S its up to you.. by this way you can add more Amps to your system...and prevent the main swicht overshoot

oh. i have only 1 ph power.

all home has 3 phase power, to distribute for the whole house, just look to the electrical board and check the main power source, it could have 3+1...

As far as i know, homes in North America are still using single phase power. Three phase typically runs down the street and a transformer mounted to the pole (or underground) brings in 220-240V to your home, where it is distributed to your outlets at 110-120V (expect your stove etc which will be 240V)

Other countries use three phase power to the homes but typically only get a single leg and a neutral from the main grid.

you should ask for 3, and pay a litle bit more...

That's what I though. Amuricans are to dumb and we would fry ourselves if we had 3 phase and 240 to all outlets, then we would sue the shit out of whoever put it in. BRILLIANT!!

Blankets showed up today. Stoked, they look great. 240v 2400 watt. They look big.

SRP, I'll put yours in the ups tomorrow, or Wednesday at the latest.

they never answered my request for a quote. i ended up going through OEM: not stoked. I also screwed up on my end and tried to cut costs by getting a smaller blanket. I went too small, especially for my double ski press. if anyone wants a 4"x85" wide blanket, let me know.
