Re: Hydrostatic 3250-Plus C wire
You can get what Honeywell calls a fan center which is a relay and transformer in one.
The rib relay is about $20, a transformer is about $30 maybe. So a fan center is about the same $. I like the rib relay because it has an idiot light to tell you the relay is calling. A fan center complicates thing but thats just me.
You mount a 4" square box bring 120v to it. Mount the rib relay and the transformer on the box bring the thermostat wires to it and two wires to start the boiler and your done.
See the attached fan center

It's not a cult, I am free to leave any time.
Re: Navien condensing boiler settings troubles
Okay, here's an update on what I've done so far… From the service menu, I lowered the absolute minumum and absolute maximum supply temperatures to 28C and 72C respectively. From the regular menu, I set the outdoor reset to the user-defined curve, changed the outdoor high temperature setting(for outdoor reset control) to 18C, and disabled the WWSD function. From last night's low of -23C to today's high of -11C, the boiler seems to be following the thermostat setting nicely. Things seem to be on the right track now, but I'll have to wait for some wider variations in the outside temps to know for sure. In the meantime, I'd like to thank all of you again for the guidance and great suggestions you've given me!
Re: taco sentry zone valve
@heatguy24 Please see below. The resistor would go across the 2 power terminals on the Zone Sentry valve actuator labeled C-W/y
Re: Radiant flow not pushing fast enough
I would purge air from the loops and add a halfway decent microbubble separator. You have short loops, and not many of them, the smallest pump should still be overkill, if its not flowing look to the system, you have no lack of pump on this system unless your loops are a whole lot longer than the mention 200'
Re: Triple Aquastat
why are there 3 transformers (and probably a 4th for the indirect that we can't see)? it is probably time to pull all the wires out and start over before you condemn any controls. it looks like someone added the indirect with as little effort as possible so there is now wiring going everywhere. figure out what goes to the t-stat and the aquastat in the indirect and piece it together from there.
Re: Radiant flow not pushing fast enough
(UPDATE) so the Winter is here. My brother helped me move the circulator pump just after the mixing value which was prescribed by the majority of responses. The floor is getting the necessary hot water to warm up the zone. I had to change the taco pump aswell. The old pump was pulling hot water through the manifold but didn't have the power to push all the loops, all the way through and back to the cold side of the manifold. The pump possibly got burnt up on the old setup before moving it. I now have 120⁰ going out and approximately 90⁰ coming back.
Thank you all, Happy Holidays
Kudos to tech support at Rinnai
I just want to give a thumbs-up to Rinnai for their tech support. I installed an new "I"series boiler — 120MBTUH (heat only w/ indirect) as a replacement for a Buderus GB142. It wasn't "playing-well" with Honeywell 'round' (no mercury) thermostats. So I put in a Taco 6-zone pump controller as an interface. All is well. Thanks to James and Mark at Rinnai….ON A WEEKEND!
