WarmTX
User guide
Manufactured by RC-Thoughts – powered by Xen
Made in Finland
Description
WarmTX is made for keeping RC-operators hands warm inside radio mitt. Especially with flying RC-models hands are
usually either bare or with very thin gloves and in -25ºC / -13ºF fingers are getting numb pretty fast. WarmTX's heating
pads are meant to be installed inside radio mitt so the heat from them keeps operators hands warm and allows the operator
to have more pleasant hobby-day out on the field even during colder times of the year.
Control unit is ready to run, assembled, programmed and tested by RC-Thoughts prior shipping. Soldering and eventual
shortening of heating pad wires is done by user depending on installation. EC3 male-female pair is included. Batteryconnector is not included. Please read this user guide before using your WarmTX.
History
WarmTX is designed by a Finnish guy called Xen some years ago. The idea, construction and choice of components is
very thoroughly tested by Finnish RC-heli community during these years. Since Xen is more of a design-guy and I'm
more of a assembling-guy we came up with this scenario where RC-Thoughts is getting WarmTX out to a wider
audience. WarmTX is designed and assembled in Finland.
What's included

2 pcs
1 pair
Control-unit
Heating pads 100x100mm with 50cm wires
EC3 connector + heat shrink for heating pads
Wiring and assembly
Wires coming from control unit are two white, one red and one black.
White wires
Red wire
Black wire
= Power to heating pads. Polarity is not relevant.
= Positive wire from battery
= Negative wire from battery
Solder a connector of your choosing to battery wires coming from control unit. Red is positive, black is negative.
Connecting battery leads wrong way will break the control unit.
If necessary, shorten the heating pad wires and solder one EC3 connector to heating pad wires so that you have the
heating pads in parallel as picture below. Heating pads have no polarity.
NOTE: Do NOT connect any other battery than 3S to 6S LiPo to WarmTX!
DO NOT MAKE ANY HOLES TO HEATING PADS!
Testing and operating WarmTX
Make sure heating pads are connected correctly and plugged in to control unit. Connect a fully-charged battery to controlunit. Green LED is lit, everything is ok, Red LED is off, no heating power selected.
On every press of the button you can select one step higher heating power. See picture below.
While running WarmTX indicates selected heating-power with blinking red LED on control unit corresponding to
selected heating power level. (Picture above.)
If you are on the highest heating-power the next press on the button turns heating off.
You can also turn heating off from any selected heating-level by pressing the button for longer than 0.5 seconds.
Power to control unit remains on as long as there is sufficient voltage connected.
When you are done using simply unplug the battery from control-unit.
Next time you connect a battery to control-unit WarmTX will go automatically to previously selected heating-level.

Attention
Heatings pads are not supposed to be applied directly to your body. User needs to take the heat of heating pads into
consideration while planning the setup. Always test before use, search for the most suitable heating power settings for
your application. Never leave WarmTX unattended during use.
Heating pads get's hot, hot things can burn the user and melt equipment. It's called “heating” for a reason, use WarmTX
wisely.
Do NOT cut any holes to heating pads! You'll short the pads internal wiring and create a short. This will break WarmTX!

RC-Thoughts
I started the blog www.rc-thoughts.com during winter 2014-2015 for a place to do some writing about my Jetitransmitters configurations. Some time after that I slipped into very small manufacturing of one small product
LogicSwitch. And since it became somewhat asked item from readers I decided to start selling it through my website. I'm
currently also JLog retailer in Scandinavia through RC-Thoughts.
And now it's time for WarmTX :)
RC-hobby is what it says, a hobby. And freezing is not part of a hobby, it's inconvenience. WarmTX takes the fun back to
RC-hobby during colder times of year.
I'm not running a traditional RC-shop, I'm selling products I use myself and can stand behind. I hope you'll enjoy these as
much as I do.
