# Vacuum Oven - changing from celsius to fahrenheit

Ok, so I bought a 0.9 vacuum oven and have used it for a single run successfully.

But for the friggin life of me I cannot work out how to change from celsius to fahrenheit. I’ve even messaged the sellers who are as stumped as me. I can access two different settings menus by holding down the set button for 3 secs, then entering either 3 or 9 as the last digit on the display and pressing set again … but nowhere in these settings is there one for c to f.

The display itself even has a little led for fahrenheit, so its gotta be possilble.

Anyone got any idea?

Its a Baked Oven 0.9cbft looks similar to lots of others …

May not be possible. Honestly, since getting into cannabis and chem in general, all I use is °C.

(°C × 9/5) + 32 = °F

yeah i’ve ended up laminating a conversion table …

My rotovap won’t change to Celsius so I’m on the other side of that issue- you should learn to think in Celsius it’s so much more sensible and most scientific articles and work uses metric measurements

I reached out to someone on alibaba and they said:

“It’s very easy to switch to Fahrenheit. We will tell you after you buy the oven.

This might work. The controller looks similar to one I’ve worked on in the past.

To Change Temperature Units from Celsius or Fahrenheit:

1. Hold Set key (left most) for about 5 seconds until “Lc” appears.
2. Increase “Lc” value to 23 and press set
3. “bd” will apear. If value is at 1 then it will display in Fahrenheit. If “bd” is at 0 then it will display Celsius
4. Hold set key again until it goes back to the original screen.

Give it a shot. Goodluck!

What kind of roto do you have?

These instructions work on a Solvent Pro Roto by BVV.

1. Press and Hold Knob for 5 seconds (LY will appear)
2. Turn knob and set LY to 0168 then press the knob. Keep pressing until you see “CF”
3. Set CF to 0 for Celsius or 1 for Fahrenheit.

Hope this helps. I know AI has similar instructions, might be different code tho.

This is what the supplier told me … but If I enter 23 (or 0023 on the four digit display) and then press set, it just takes me back to the default display (current temp) … if I just enter 0003 or 0009 I can get extra menus, but none seem to effect the F/C setting

thanks, but yours does seem different to mine
