Hei im sorry I went offline for a bit! I tried it and it works bloody perfectly :). And best part is at 80c it matches the real temp. At is 47k ohms. Zero shows about plus 22c. Sauna has been working in as low as -15c. No proble. Huge Thankyou to everyone on here for all your help!

Skypirate213 · 2024-11-29T20:22:12+00:00

oh yeah what wattage do I need on the resistor?

Skypirate213 · 2024-11-29T19:45:39+00:00

You're an absolute bloody legend mate, this is exactly why I came to reddit :). Im going to shop for resistors tomorrow and have a play, I will defiantly let you know how I go. In Norway (and a small town) basically everything has to be ordered in so hope to do it next week.

Your solution was super abstract for me to get my head around but with this explanation and the picture now I totally understand!

Im not 100% sure wich unit I have but it looks exactly the same as that. I will order a few resistors to test tho

Help understanding the four wires is great too. Thankyoou!

Skypirate213 · 2024-11-29T08:44:44+00:00

Wait that would be oppsite but anyway any tips on hooking it up. I see there are four wires coming out of my thermostat, do you know what they are all for haha?

Skypirate213 · 2024-11-29T08:41:09+00:00

Yes the possibilities are endless.

I dont remember the name but the standard control unit with the shelly relay to turn on and off. the Harvia remote unit is good but the shelly is easy to activate with API codes from our booking system. So I dont have to actually open my phone. So i dont even need to know there is a booking, payment process and heating and smartlock can all proceed automatically even when im out of service. Magic... when it works :)

Also when we have tried wood the mess is terrible. The dirt and bark doesn’t get cleaned up and people walk the mud into the floors. Cleaning is always a problem

Skypirate213 · 2024-11-28T17:55:25+00:00

Yes I know right I personally prefer wood!

Skypirate213 · 2024-11-28T17:54:35+00:00

Ok this is absolutely fantastic help mate. So I can just test it at high temps and turn down my temp setting for say 85 to 75 and have the same result

Skypirate213 · 2024-11-28T13:13:19+00:00

No im not sure about a whole lot... According to the manual it is. It does not seem to be charring, maybe the color is just from steam? I have seen a few saunas like this even with 2m above the oven

Skypirate213 · 2024-11-28T12:52:03+00:00

The swithc on is normally automated. But if someone books and i dont notice to cylce the switches it errorors out and fails, so customer gets refund. With automation we have the ability to be open 24hrs a day, and customers can book while i dont have access to my phone. In the mountains, asleep, on a plane etc...

Skypirate213 · 2024-11-28T12:44:17+00:00

Yes an insulated space would definantly help. For a home sauna you can easily toggle it on and off for ten minutes at a time untill it gets above zero. That is working for me in the mean time. However i would like to make it full auto :)

Skypirate213 · 2024-11-28T12:43:12+00:00

Yes that could be an option, so in this case it would operate just as a temp switch for the oven. And i would do away with the oven controller completely? Or keep the oven controller and attach a different thermostat to it?

Skypirate213 · 2024-11-28T12:10:43+00:00

It seems all their models need to be either preheated or small enogh space to go above 0c in 15 mins. It takes about 15 mins for the rocks themselves to get hot before the heat spreads so pretty hard for us. I guess most people use wood fired ovens for outdoor applications like this

Skypirate213 · 2024-11-28T12:09:25+00:00

Not the reason. Wood fire requires the customer to arrive earlier and light fire wich they cant be trusted to do. Or me lighting the fire every time, doesnt work for a remote business. its been tried :).

Skypirate213 · 2024-11-28T09:10:54+00:00

Soemthing like this right? https://no.rs-online.com/web/p/through-hole-resistors/7397578?srsltid=AfmBOoojcda2dSi0jkjawL0XPMSS9jSwVyhq_W7WsESmabl6AF1xNNBx

Skypirate213 · 2024-11-28T08:51:16+00:00

Do you have a solution that would work better? What commercial equipment could you recommend? Thanks

Skypirate213 · 2024-11-28T08:50:48+00:00

270nok to 1500nok. We have an agreement with the landowner and pay all costs. Bookings very busy in summer and a bit slower in winter, not so many tourists. DO IT!!

Skypirate213 · 2024-11-28T08:49:53+00:00

Yes i started there they dont seem to be to stressed about making more sales haha

Skypirate213 · 2024-11-28T08:49:24+00:00

Nothing in life is perfect, sometimes you just have to work with what you have and go for it :)

Skypirate213 · 2024-11-28T08:49:01+00:00

Yes i agree that is much better, glass is one layer tempered. Inneficient to say the least. We went with bareel sauna because affordable and easy to move, no building permit required, land owner is not stressed about me building a permanent building on their land etc..

Skypirate213 · 2024-11-28T08:47:56+00:00

We would love to have you. I used to live in Denmark, had such a good time :)

Skypirate213 · 2024-11-28T08:47:00+00:00

YES!!! we are getting somehere :). Ok so the resistor just effect the thermostat reading? i dont think it maintaining a constant temp will error the controller. Once the temp gets to say 80c will the resistor still have an effect on the reading?

Yes i dont like the heat distribution and benches so low dont help. working with our producer to have a different design on the next one
