Thermostat for garage

[70RSCamaro]

Hi Guys

Has anyone found a simple manual thermostat that can be set down to 35 -40 degrees F? All of the ones I can find only go down to 50. I just want to be able to keep it above freezing when I'm not in there.

thanks

I used this one.

Ordered it off Amazon but my local Menards carries it, and I think I saw it at Lowes or Home depot also.

How is the T771 thermostat working out ? Thinking of ordering the same 1 for my Mr Heater.

Thanks'

I use that same one that Lambo Nut posted in my garage.
I love the on and off switch and the Low Setting.
Very Simple.

I will let you know early next week. Right now I just have the call for heat jumpered in the unit. I plan to install the t-stat this weekend.

Looking forward to your feedback on the t-stat.

I looked at the Honeywell. Just my eyes are not getting any younger. I like the large digital numbers on the Pro1IAQ T771.

Thanks' for the info

Somehow missed this thread when it first appeared..... probably a good thing........

Glad you asked this. Just last night and again this morning, I was experimenting with the lowest setting of my cheapo White Rodgers Thermostat that came with my Lanair 200K BTU used/waster oil heater.........

Link to the install thread

I discovered that with the thermostat set down against the off stop detent, which is as low as it will go, it holds about 54-55°F. I would like to have it hold a lower temp for nights when it goes into the teens and I want to leave the heat run all night. 55 is too high to leave it all night (3600 sq/ft steel building).

Normally, when I am using the heater and working in the building, 60 is seeming to work out as a comfortable temperature, but we sometimes have a few nights of mid to high teens temps and on rare occasion every few years, it will go single digits. Last winter we had several days running where it never got above freezing, and this low setting would be good for that.

Edit: $29.99 retail, found it on Amazonfor $24.46

Installed this LUTRON / HONEYWELL unit for my REZNOR in my garage, that way I can control the garage heat via my IPAD / IPHONE / RTI Home Automation system.

Friday night I temporarily installed the thermostat. I should have taken a picture.

I have it mounted to a piece of 3/4" plywood and clamped to a shelf below the heater.

I really like this thermostat. It has a nice big display for the current temperature and the set point is in the upper right corner. The blu backlight makes it easy to read, but does not stay on all the time.

I used 4 wires to connect it to the Hot Dawg. I went ahead and connected the common (for power) and the fan. My thought was that I might use the fan in the summer if I need some air circulation. The dead band on the thermostat is adjustable. I currently have it set at 1 degree.

Right now the garage is not fully insulated and the ceiling is not fully covered, so I am not leaving the heater on all the time. Once I am fully insulated, I think this will be a great thermostat since it can be set down below 45F. I am not sure what temperature I will use when I start running the heater all the time, but having 40F or lower as an option is nice.

One thing I could add is that if you have an old round coil type thermostat, most of them are calibrated at the factory by indexing the coil on the set shaft. It would be guess and check type of deal, and you would have to relabel the range on the thermostat check when you got it where you wanted it. A little hassle, but it would be basically free also. No, I'm not a thermostat engineer. But I used to be. Oh, and if they locktited it in place after calibration, then you are probably stuck. But we didn't do that.

I used an old fashioned mercury thermostat and mounted it out of level. Then I set the temp at various settings and marked what the building temp was on the wall below by the lever to change temps. Working well for 17 years. Pushed all the way down, the old setting of 50 degrees is really about 38 degrees.

yes! Well done! Great way to use the mecury ones.

Well, I ordered the Honeywell low temp thermostat mentioned above. Ordered on Friday nite from Amazon, shipped USPS Saturday, USPS mis directed it to a small town PO in south Alabama near Mobile. Tracking shows arrival at the PO Dec 6 at 10:08 AM and then being scanned as "missent" at 10:37 AM, and nothing further since then.

Where do you get a good price on a PRO1 iaq t771 thermostat, also where do they sell them at ................................

 

[sarman47]

I ordered mine from Amazon.com.

They are sold by CT Suppy Inc. Price was $26.63.

Picked up mine and all looks fine.

You can also check local HVAC suppliers in your town. I work for a Contractor, so I just called up our Modine supplier, and they recommended the PRO1. I paid a little less than sarman47 ($24.**).

i also have this thermostat and am amazed at all the features i has. it easily holds my garage at 33 at night (for real, i have a cardboard cup of water in there to check for freezing). i need to adjust my swing a little bit but thats a personal thing.

my only complaint about it is that it is difficult to read at 33 degrees. at 38 degrees it is perfectly fine so i have been keeping the garage at 38 degrees instead.

I have been looking for a new stat for the garage but I wont spend $30 for the made in China Honeywell unit.

I dont suppose there is a stat made in the USA that will go down to 35 degrees ?

 

[Charles (in GA)]

Well, I got the Honeywell low temp thermostat after the PO mis-routed it. Cannot say I'm impressed. I'll see how well it holds temp and how low it really goes, beyond that, it doesn't even have a pointer to point at the set temp, you just have to take a wag. I'm used to the old round Honeywell that had a pointer that you could set accurately on the number scale.

May end up looking at the Pro1 before its over, but I'll stick with this for now. After I figure out what settings hold what temps, I can make a couple of marks on it.... Its just a shop. I just wanted the ability to go lower than 50 degrees.

Old thread that came up in my search....

I'm looking for a low temp thermostat for my shop. However I want a way to control it from the house. That way I can warm it up before heading out.

Ya I'm a bit of a sissy but why not? I know about the Nest and thermostats like it but I was hoping for something simple. On the plus side I do have a conduit going from the house out to the garage so I could wire it in. Of course that would mean two inputs (one from the house and another in the shop)

Any suggestions?

pretty old thread JohnnieMo - Like earlier said. Most hardware stores have a low temp "Garage Thermostat". I have one at my cabin, it goes down to 35 degrees. Easiest way for your instance seems what you said. 2 thermostats = 2 inputs. I know builders that do the same thing in houses, wire up a backup thermostat directly in the furnace room at around 55deg in case homeowners leave for months during winters, and the batteries in their digital house tstats go dead while away.
Easy enough if you have conduit, leave t-stat in garage at 35-40. turn up house t-stat ahead of time before going out.

Interesting idea but I don't think it would work. The the house thermostat would be sampling the temp inside the house and never activate.

K, i guess a few options for you.
1. mount it on an outside wall because it's cooler.
2. mount the t-stat wherever, turn it up high, then simply turn it down before you go out to garage...
3. or another route, run the wires through your conduit, use a mechanical switch timer inside instead of t-stat. (switches come in 15 minutes/30 min/ 1 hr, 12 hr, etc)

Another option is the Johnson A19 ABC coil under thermostat for refrigeration and air conditioning. Not as cheap as some of the options listed above but has a cool industrial look to it. No heat anticipators on this stat so it really isn't for comfort heating. I had one that came off a demolition job years ago that has been working just fine at just above the freezing point in my garage.
I turn it up and the little Reznor low profile unit heater warms up the space in very little time.

Your third idea is downright clever. I could put a basic timer in the house. Something like an exhaust fan timer. Slam it over to 30 minutes on a cold morning and it would turn on the furnace full bore for 30 minutes.

The old thermostat in the garage would be hooked in parallel to maintain a low threshold. It could also be raised up when I come out to maintain a higher temp.

It wouldn't automatically shut down each night but it is so damned clever I think in gonna try it. Ironically I already have all the parts so it is a $0 cost.

Thanks!!

I have a honeywell WIFI - about $100, I really like their software, it not only allows me to use my phone or computer to control my shop, but it sends me an email if there is a problem.

One note of caution on setting your heat below 50 degrees F when using a gas fired unit heater - and this is from the owners manual of the Sterling tubular propeller heaters:

Unit heaters should not be installed to maintain low
temperatures and/or freeze protection of buildings.
A minimum of 50°F (10°C) thermostat setting must
be maintained. If unit heaters are operated to maintain
lower than 50°F (10°C), hot flue gases are cooled inside
the heat exchanger to a point where water vapor (a flue
gas by-product) condenses onto the heat exchanger
walls. The result is a mildly corrosive acid that
prematurely corrodes the aluminized heat exchanger
and can actually drip water down from the unit heater
onto floor surface. Additional unit heaters should be
installed if a minimum 50°F (10°C) thermostat setting
cannot be maintained.

Dave*99. I have a LP Big Maxx 80000 btu. Im assuming mine falls under the same caution as your's?? I will check the manual this evening. I was wanting to keep it just above freezing.

I expect your Big Maxx will have the same warning. Like my heater, it has a tubular heat exchanger . I don't have a manual for your heater but I looked at a photo online and it looks very similar to mine.

Thanx Dave*99. Ill check my manual. My heat exchanger has 10 yr warranty they claim but i want to avoid that if i can.
