Electronics / Re: My thermostat journey and wiring instructions
« on: October 18, 2013, 06:27:43 PM »
I think you described exactly what I need.
So-- you are able to have wood heat with indoor furnace "fan only" kick in at - say 72 degrees.. But if the room temp happens to drop down below - say 65 degrees, the gas burners in the same indoor furnace kick on with the "auto fan".
And you accomplished that with a PRO1 iaq T755 thermostat and the wiring list you posted.
done.. no more to do... right? (I do not have or need any controls on the OWB.. it just runs by itself and supplies the heat exchanger in the indoor furnace plenum box)

Electronics / Another dual fuel hookup issue (Nat Gas & OWB through same furnace blower)
« on: October 18, 2013, 06:18:42 PM »
I've been looking through the posts, but a lot are confusing with how the hookups are with aquastats & such.
My issue is much simpler than that.
New Natural gas furnace in the basement.
Outdoor wood boiler that pumps 24/7 when I turn it on in November until April.
OWB piped into a heat exchanger in the Nat gas furnace plenum box.
Last year, I had 2 thermostats side by side. The Nat Gas thermostat was set to a much lower temperature to avoid kicking on the burners. (65deg F)
The adjacent OWB "heat only" thermostat was set to kick on the "fan only" when the temp dropped below 72
Right now, the outside temp is fluctuating... not enough to start the OWB yet.
So-- I want to have periodic Nat Gas heat. -- But my setup which I though tested & worked last year -- does not work now. In fact, I can't get the Nat Gas to fire at all.
HELP----
I need to find a single thermostat that can handle my exact needs. (fan only for 72deg.... fan & gas heat for 65 deg)
--or--
If that is not possible, I need to figure out the wiring correctly between the 2 thermostats. -- drawings are nice.
Thanks

General Outdoor Furnace Discussion / Need wiring help
« on: October 21, 2012, 07:04:11 PM »
I bought a Big John - Johnson outdoor boiler from a friend. I have it all hooked up except for the electrical. My friend forgot how he wired it up. Here's a drawing (attached)... There are 2 blowers on the front of the unit.
Anyway.. I think the lightswitch in the front of the boiler is for the jar light.. but it looks like a 3-way switch.--- where the switch on the rear of the unit is a normal lightswitch.
