MK 160 remote control - Temperature

Hello,
I have seen a previous thread about the temperature range of the MK160 remote control kits and I have
a similar problem.
I need the kit to operate in sub zero temperatures. ( currently working in -16 degrees C)
Does anybody know how I can go about sorting this problem out.

Previous poster mentioned something about needing an industrial IC ???

Thanks.

Can you put he PCB in a box and include a heating resistor
EX: at 12V add a 1W / 220ohm resistor in the box, this will heat the components.

I am using an box in an insulated enclosure with a 240v 60w bulb as a heat source at present.
It is working most of time, but is not safe and is expensive.
A 12v resistor would not produce enough heat, ambient temp. is -16 degrees C.
