Making a single loop into two zones

Posted by Boiler newbie on November 18, 2004 at 10:37:11:

Is is possible to wire a circulator incorrectly? Or is it AC and doesn't matter? A new one was installed and need to hook up previous wires. There isn't any disctintion on the circulator's wires.

My plumber put the expansion tank and circulators on the return side. Is that OK? it's a fairly small system.

We split the original zone in two using a multiple series circuit design. Do I need a second "pump relay"? Do they make relays that control both zones? I have separate thermostats installed. The existing relay is a L8048 Honeywell.

Based on the multiple series circuit design diagram on the site, it looks like there should be Flow Control Valves... I don't believe he put those in. Are they required? He says the circulators are designed to prevent this.

Thanks for any input.
