Taco zvc406 to control 120v pumps through rib2401b relay wiring diagram

I currently have a Taco ZVC406 Zone valve control. I have changed my mind and would like to control individual pumps instead zone valves. I would like to do this with the use of RIB2401b 24v to 120v relays. Could someone show me or explain to me exactly how to wire this.
Any assistance is appreciated.

Won't it cost you darn near as much for the additional relays, and the time to wire it all up as it will for an SR-506 panel?

SR506-EXP-1 - Taco SR506-EXP-1 - 6 Zone Switching Relay w/Priority & 3 Powerports

Make sure you really want to go through all the trouble first.

You can always sell the 406 and get some money back on the deal too.

If you are set on using the relays:

Work out how you will safely mount the relays so that you don't have exposed 120VAC wiring hanging out all over the place.

Wire WHT/BLU and WHT/YEL from the relay to the Taco zone valve 1 and 2.

Install a jumper in the Taco panel from 3 to 4. This is needed so that the Taco panel will operate the endswitch relay to fire the boiler.

On the other side to run the pumps, you will be using the YELLOW and ORANGE wires.

120VAC HOT (BLACK) goes to YELLOW

ORANGE goes to HOT (BLACK) connection on pump.

120VAC NEUTRAL (WHITE) is connected to the NEUTRAL (WHITE) of pumps.

NJ Trooper. THX for the quick response. The extra work isn't an issue. I love this stuff. I'll let you know it works out.

Domestic Hot water circ pump.

NJ Trooper. Your advise was perfect. All zones are firing as required. One more question. How do I wire the system circ pump which circulates from my domestic hot water heater through the heat exchanger? I think I am missing something with the wiring diagram. I just want the pump to fire when any zone turns on.

I think it's me that's missing something... what " system pump " ? what " heat exchanger " ?

You need to tell us more about the system. All I knew was that you wanted to run pumps with a zone valve panel.

I am running an indirect system. It has a circulation pump that pulls water from a Polaris hot water heater through a heat exchanger. The distribution side has 4 zone pumps ( I know I'm using a 6 zone control) and I need the circulation/system pump to come on when ever anyone of the zone pumps come on. I hope this clarifies it.

No, not really.

Are you saying that you are using the Polaris as the heat source for your central heating?

Do you have a system diagram I can look at?

I think you are saying that you have a Polaris water heater as the heat source, there is a pump through a (probably flat plate) heat exchanger, on the other side of the heat exchanger you have the four central heating zones.

I think I understand this correctly?

Does your ZVC 404 have a " MAIN END SWITCH " and an " EXTRA END SWITCH " ?

Yes. The system is as you stated. I am using a flat plate heat exchanger. The water heater has a 50 gal tank and 1" output/input line. It is capable of running at 185F. I have my domestic supply running through a temperature control valve that only allows a max of 125F. The pump in question, (stainless steel guts and domestic supply rated) is the one I need to come on when any of the supply pumps start. My ZVC406 has a Main end switch, an extra end switch and a set of dry contacts.

System is up and running and works like a charm. I love the heat it gives off.
