I have a sauna heater from Harvia that had limited information about the controller prior to receiving it from Ireland after a 4 week wait. The stove itself seems to be compatible with 220v US wiring, but the controller does not immediately seem to be workable without some serious help from the internet. I unfortunately took the 230V 1N~ in the stove documents to mean that I could do 1 phase 230V only to find out that the controller does not contain an option in the documentation for that.
I really could use a general solution (or even wild ideas) along with the size of breakers and wire needed for a 70 ft run from the breaker box.
I am posting the board connections, heater connections and charts from both manuals in desperate hopes that someone smarter than me will have a solution as this is not returnable.
I do have a 3-phase rotary converter in the garage that could probably power it as a last resort, but firing that thing up in the garage every time we want a sauna does not sound remotely enjoyable.
My house has 1 phase 120V/240V service.
If anyone sees a way that this can be installed without 3 phase service and without using the rotary converter, PLEASE HELP!
The solution I was hoping would work below (and which worked great for 2 weeks) wound up burning out the controller board (transformer and some of the relays). I am amending this question to try to discover a better board for this set-up:
Is there anyone out there who can tell me how this circuit would in any way regulate the kW that make it to the stove, or is that all just a function of the heating elements in the stove? It is a WX361 controller board from Harvia and uses contactors (ZSL-940) to open and close the power to the stove. I think there are two contactors there simply to allow the overheat protection (A1 and A2) to cut power on overheat. If I use this board, it will now be hooked up 240v 1Ph with a neutral.
