Custom 6 Zone Panel - S/R Temp Display

john p_2

Looking to make my own custom panel to display S/R temps of my hydronic heating zones. Thinking I could do this relatively cheap using LED temp displays from China bought on EBay. Not sure if there is anything out there like this as all I'm looking to do is sense and display temps, not control them. Would love to see any custom ones built by members from heating help...thanks.

Here are some from the wood burners over at hearth.com. Most guys custom build their own.

One brand that is web enabled alsohttp://www.controlbyweb.com/x300/specs.html

Nice, thanks Bob. I like the one to the far right with the powder blue cover - exactly what I'm looking for.

Bob, not sure if that powder blue one that I like is store bought (doubt it) but if you can give me any info on that one such as part # for the LED displays and maybe a wiring diagram, I would appreciate it.

The photo on the far right appears to be of a 12" x 12" x 4" gray PVC (NEMA 6P) J-box.

Yes thanks SWEI. Appears custom made. Would love to get exact part#'s for the displays and a wiring diagram...hoping to power it from the Taco Zone Control Panel.

Here is the response from Jim regarding the homebuilt.

Wow, thanks so much Bob

hot_rod

Show us a picture of the finished product, when you are done..

john p_2

For sure...

Bob, the attachment from Jim gives only part #'s for the sensors not the displays, any chance you can get the LED display part #'s and I really would love a wiring diagram/sketch if at all possible.

go to e-bay, enter DS18b20 digital temperature meter as he mentioned, all sorts of sizes, colors etc. Be sure to get them that read F. Just wire the sensor to the meter, battery of separate power source.

I second Hotrod and highly recommend controlbyweb, although they don't make a device that itself has an actual digital display; however, it can output digital information to a web browser. As for the panel face itself I used software from, this website to build lots of custom panels such as the one here. They are pricey but also recommended.

Wellness....like the temp gauge used in the photo you attached, can you tell me where you bought ?

john p_2

Guys, I do not see any (affordable)temperature monitoring devices, LCD or LED that meet all my criteria - max temp 200 degrees, Fahrenheit display not C, and 24 VAC. I do like the Azel dual temp display DS-60P but thought I could design a cool looking panel of my own for less money...

@johnP. For cheap gauges I'd recommend the Docooler Digital Temperature Controller, which show temps, only. The gauges I used in my panel are Dakota Digital and require separately sold sensors but you can measure PSI and Temp. You can see more at my site, below.

Wellness...wow, what a website!!?? Very nice, that is awesome.

john p_2

Wellness...I see the 24VAC to 12VDC power adapters on the website but I'm not sure what the best way to go as far as powering/wiring up for 10 gauges (5 zones monitored - 1gauge for each S & R)
Not sure whether there is enough power to grab it from my Taco zone control panel or bring a dedicated AC line straight to my custom panel and from there reduce to 12VDC but it's far above me which is the correct way

Wellness

I used those 24VAC to 12VDC converters only to power 12vdc LEDs, since the Taco zone on/off display is so small and hard to read.

If all you want is to display boiler temps, just design a panel with FrontPanel Express or mount the Docooler Digital Temperature Controller in a large switch box and cover it with a regular Decora wallplate and insert the probe in the appropriate sensor well in your zone piping. Each Docooler Digital Temperature Controller will require 24vac from a transformer unless you buy the 110vac model. See the customer images at Amazon under the product review section. Lots of ideas there. Hope that helps.
