G6 Heat Controller

New LED battery status indicator ring. The LED indicator ring shows both the 5 different heat levels and the battery charge status. Here is how it works.

  • When the UWLD heat controller is first plugged into a UWLD battery canister the unit does a self-test and lights the green LED then will shut off.
  • When the unit is turned on, by pressing and holding the Piezo button in the center for at least 3 seconds, the green, yellow, and red LED’s with flash in order. The unit starts on level 5 the highest level, so the LED indicator will flash 5 times, indicating the level it is on.
  • Then the LED will go to constant on showing the battery level. Green is for the top 1/3 of the battery, yellow for the middle 1/3, and red for the bottom 1/3.
  • Each time the Piezo switch is pressed and released it will change to the next heat level. From high it will go to low – one flash, then two flashes, then three, etc.
  • To turn the unit off the Piezo switch is pressed and held for at least three seconds.
  • The heat controller works with all 12v heated undergarments.

One of the biggest issues with current heated systems is the diminishing heat output as battery life dwindles. The UW Light Dude heat controller’s innovative design offers functionality for a wide range of diving that requires heated undergarments and addresses the need for warmth when you need it most – longer duration dives.

There are 5 power settings and each setting gives the same heat output regardless of the battery voltage. Research has shown that cooling on the ascent/decompression portion of the dive has a negative effect on decompression. Dr. Neal Pollock, from DAN, has summarized a number of studies that make this point, he has 2 YouTube broadcasts covering this information. Broadcast 1, Broadcast 2. Optimal for decompression is to be cool on the descent/bottom portion of the dive and warm on the ascent/decompression part of the dive. Other systems cool off when the voltage drops from the battery canister the heat output also drops. Our 5 heat settings are spaced to give heat output from -3c to 20c (23F° — 68°F ) water.

The controller comes standard with a UWLD Stack Cap allowing it to be used as a single on a battery, with the included blanking cap, or with a UWLD light canister cap stacked on top of the stack cap. Our other caps are available as well.

The controller can’t be used with other manufacturer’s lights that have E/O cords. Plugging a light into our controller will damage the light. We don’t provide E/O for our lights eliminating the possibility of plugging our controller into our lights accidentally.
