Old switch 2 wires. New switch 3 wires. Now what?

I live in Perú, so this is all 220V.

This is my situation, I have a water heater with its own breaker in the box (blade type), out of that come two wires (from a double-pole breaker, 220V I assume). Those two wires were connected to a simple throw-switch, two came in, switch, two came out, went directly to the heater. The heater has three wires going into it, the two coming from the switch and a third connected directly to the ground in the breaker box.

What I want to do is replace the switch with an electronic timer I've bought, but I have no idea how to do this...can anyone help?

Edit, hmm, can't post inline images, have to put a link.

You need a different switch.

I would ask why you want a switch at all, but that is a different question.

I need the switch because the heater is responsible for about 35% of my monthly electric bill and I want to take a little more control of when it shuts on or off.

Darn, I thought this switch would work. I guess I should go back to Ace and switch the switch.

Are you on a time of day based billing where they bill you different rates at night than during the day? If not then you won't be saving any money putting the heater on a timer.
