This is how to calibrate the sensor and configure a limit of 45-50 degrees C:

  1. Look at a thermometer to check the current room temperature. I’ll assume it says 22 C.
  2. Turn the light off and wait for its temperature to settle to room temperature.
  3. Click 10 times.
  4. The light should blink once, then flicker or “buzz”.
  5. During the “buzz”, click 22 times to tell it the room is 22 C.
  6. The light should blink twice, then flicker or “buzz”.
  7. During the “buzz”, click 15-20 times to tell it you want a temperature limit of 45-50 C.
  8. Wait for the light to return to off.

Afterward, it should attempt to keep itself below 45-50 degrees C.

Thank you very much. And what is the scheme for setting the desired temperature? (if you need to change the temperature) One click is how many degrees?

1266

The temp default setting is 30, so if you want to change it you add to the 30 (hence, click 15 times to get 45, or 20 times to get 50)

1267

Thank. Please specify.
These items (5.6) are required to perform or make “Click 10 times” (3) and perform “During the“ buzz ”, click 15-20 times.
“hence, click now to 30 (hence, click 15 times to get 45, or 20 times to get 50)”?

1268

Yes. The lowest value you can set the Temp limit to is 30C by not clicking at all. Each click is 1 degree higher than the minimum of 30.

Just dont forget to calibrate the temperature sensor during the first set of flickering.

1269

Thanks for the answer.
So you need to do it.

ToyKeeper, DB Custom, nick779 !!!. Friends, thank you very much for your help. Now completed all the recommendations. How to check the temperature set by me?

1271

This will greatly vary based on a number of parameters such as your ambient temps, specific battery being used, and emitters that you have, but some rough figures were provided by TK in the original post.

1272

Not quite. If you don’t click at all, it will leave the value unchanged. The lowest value the user can set is 31 C, by clicking once.

All config menus “fall through” with no changes if you don’t press the button.

1273

valera, we sometimes get caught up in the numbers as if it were an exact science. It’s really not. These parameters get us close and that’s about as good as it gets. You can measure the amperage your light is making at different levels and then use this information to estimate run time based on the capacity of the cells you are using, but again this an approximation and not an exact science as the diminishing cells will yield lower and lower current and the run time will gradually extend accordingly. :wink:

Friends ! How to check the temperature of the installed temperature control.
I did everything according to the recommendations, and how to check it

1275

To my knowledge you can’t read out the temperatur limit what you have set.

But you can read out the temperature of the lamp:
Lamp is OFF: 3 clicks = battery voltage, 2 clicks again = temperature.

Hint: The temperature is from inside the microcontroller. There is probably a little difference between outside when the lamp was on before.

1276

Or you could leave it for a while and let it stabilize, then check and it should be quite close to the ambient…

1277

At D1 can be determined. After 10 quick clicks the flashlight flashes the current temperature limit. Is there no such possibility on the D4S?

“**But you can read out the temperature of the lamp:

joechina Thank you very much

Made 3 clicks (from off) blinked 3 + 6 times. Carried out a test device-3,6v. The voltage is correct. But after 2 clicks 2 + 29. What is it?

1278

The D1 uses RampingIOS v2 which is a custom firmware.

On the other hand, the D4S uses RampingIOS v3 which is just Andúril with some minor changes requested by Hank.

If you compare the code or the manuals, you will see, that currently there is no way to get the current set max. temperature.
You can of course, update RampingIOS v3 or Anduril to do that. But you lose your current setting when flashing.

1279

No.

In RampingIOS V2, the limit was set by letting the light get hot. It could also display the value, to help the user see if they got the specific value they wanted. In practice, this would often take a few tries, and people had to guess until they got close enough.

In RampingIOS V3, the user can set the value directly, instead of using the sloppy “release when hot” method. So there is less need to display the value.

1280

To blink out the temperature:

  • switch off the light
  • Click 3 times for voltage
  • Click another 2 times for temperature blink out.

(Edit: I will leave it like this now, but the next time I’ll refresh the browser first… Promised! :sunglasses: )

Well, just finished an infuriating flash session with my D4S.

It absolutely REFUSED to flash with the 219c attached. Desoldered them as I was switching to XPL-HIs and it immediately flashed with 0 errors. Not sure if I got lucky the first time, but I repeatedly got transmit errors around the 1% and 60% mark. Im thinking its more hardware related as in with my laptop, and the low vF emitters or something. Really weird.

1282

No, corrected from Toykeeper.
Lexcel wrote you must desolder the AuX-LEDS on the ROT66 to flash it. Maybe that is the same reason on the D4S?

1283

Could the 219C have been reflowed in an incorrect orientation? A short there would have prevented the flash. Low Vf wouldn’t have done it, at least I’ve never had that be an issue in all the multitudes of one’s I’ve flashed…
