Primary Pump Wiring

doug_10

Wallies,

I am setting up my system as follows; Primary loop feeding through an Ergomax for radiant, with the rest of the loop for three high temp zones (before Ergo) and one low temp zone (after Ergo).

I have an Argo (not Ergo!) panel for hooking up my three radiant zones (one pump and three zone valves), and will connect my primary pump here as well if I can, but I also want to run it on any call for heat...and also whenever the boiler fires (tankless coil, maintaining temp, etc.).

Is this possible? Can I have the relay power two pumps together? I'll admit I would rather not find out the hard way due to my inexperience w/ electrical things :-)

I want the boiler to heat all 40 gallons (boiler + Ergo + piping) of well-insulated water every time she fires. Doing it manually, she runs for a minimum of four minutes with no heat calls...used to be about 90 seconds. It's a cast iron boiler w/ Beckett burner...no outdoor reset, constant circ, etc. I reset the temp. myself as needed.

Right now I "borrowed" the t-stat from the dining room to run my primary pump...I have it programmed pretty well for the times when heat and HW are need but it's a temporary fix - plus there's a zone with no warm floors :-0!

Maybe a set-up like a Boiler Boss from Erie? I'm in my boiler room at least once a day...two or three times during the heating season...so manual stuff is fine (to this point anyway) for a nut like me, too.

My tech is a good guy, but not a hydronics guru like the Wallies...

When this whole set-up is done, I'll have quite an interesting few items to share with The Wall.

Seeking any advice...TIA. Take Care, PJO

From the sound of it, you're making an effort to do it right and I think you should look into a Tekmar or like control. It will give you the flexibility and primary pump control and give you reset, which will save you enough the first year to pay for the control. Find your local rep and have him set you up with the right control for yor application.

Pump

If I'm undedrstanding you correctly I beleive that the primary pump would be controlled by the boiler control. When there is a call for heat the secondary circ will come on and cloes the contacts in the Argo panel (tt or 5&6)that will go to tt in the boiler control and fire the boiler and run the primary circ. This is how we usually pipe them when useing a simple control stratigy. Hope this helps
