Multiple Pump Controller or Switching Relay for Buderus

I currently have Buderus G334X hooked up to one large Armstrong pump and am considering converting into 4 zones with smaller Grundfos Alpha pumps .

My Boiler does not have the fancy Buderus controller on it. My question is this.

What can I use as far as a pump controller or switching relay. Does Buderus make something, does Grundfos make something or should I run down to the local plumbing supply and get a Taco SR-504 Switching Relay for the 4 pumps?

Any help here is greatly appreciated.

If you are only going to be switching 4 pumps and sending a boiler demand to the boiler for heat, then the Taco will work fine.
