2 questions - tstat and humidifier


We installed a Newmac cl86 wood oil combo furnace in september. There are 2 seperate tstats, 1 oil 1 wood. They are side by side in the living room. The oil tstat usually reads the room temp about 3 degrees lower than the wood. These are identical tstats, mounted side by side. Any idea why they would read different temps???

second question... our house is pretty dry now that we are burning wood. Is there a humidifier we can add to our system? It is a forced air system.


Thanks.

contact the manu. of the tstat some can be calibrated depending on quality if they are non-digitl with mercury switch should be able to also calibrate. being that close you could just turn the inaccurate one alittle out of level to make it right unless of course it isnt level now if its merc/sw it needs to be level to be accurate and you could look into aprilaire for a humidifier pricy but effective you want the type with a media filter or grid in it. not spray or spongepad rotating in a pan of water (mold former)

Okay, I will try to get in touch with them.


Is there such a thing as 1 thermostat that could control both of them independantly?

im was thinking you might be able to use a heatpump tstat but ill have to think bout it a little more anyone else have thought was thinking you could use the Y on heat for wood and emergency heat for oil but you might have to disable the oil at the burner (simple switch to control lo volt) so that both dont attempt to run togeather this could definitly be done but like i mentioned youd have to put something to disable the oil

Plus add isolation relays, or convert it to a 1 transformer system.


Is the hole in the wall behind both stats, sealed.

If you hook up a humifier you'll probably need a sail switch in series with the humidistat, to control it.
If you don't use the switch you have to disconnect the humidifier transformer when you're running the AC.

3 sounds excessive.

There might be subtle differences between these two thermostats; I'd look at how many terminals and what color wires are on each.

I missed that it was a combo unit.

Should just be able to use any 2 stage heat stat.
Unless, they have independant transformers for the to fuel systems.

EG: R8184 primary has its own transformer.
And the wood burner should have its own control system.

Ya know what, you might be on to something. The hole through the wall goes into a closet, which is usually cold. There is only 1 hole, and it is behind the tstat that is lower...

Im gonna seal it up tonight and see what happens.

Yes, all the wood tstat does is turn on/off the draft inducer fan.

I am a totl newb with it comes to hvac, can you explain what a sail switch is? Also, we don't have a/c... would that make a difference?


So, wanting to install a humidifier, and not knowing much about hvac, here are a few questions...

1)where should I buy one from, internet/home cheapo/blows/local hvac supplier?

2)specific brands?

3)how difficult is a humidifier install?

4) seperate componants needed?

If you don't have AC, along with its higher blower speed, then you might not need a sail switch. It's kind of hard to explain why.

something worth mentioning in case you may have not thought about it
you need a water supply in relitive proxmity that wont be subject to freezeing temps (attic) and for most humids. a drain source also that cant freeze if that criteria is met try aprilaire perhaps they have their install manual online and you could get a feel for whats involved they are a popular brand that parts are redily available for in most supply houses so you could purchase online but have local support...ken

Ya, I have a water supply in close prroximity.


Update on the tstat, there IS a hole where the wires come through right behind the one that reads lower. I didn't get a chance to seal it up last night, but will this weekend. What should I use? The wall is a plaster and lathe wall with t&g over it. Silicone? Painters caulk?
