Or otherwise how about a thermostatic switch? seems to make allot more sense? seeing as it would react to the tempreture without you needing to pish about turning it up/down all the time.. you'd not even need a controll other than on/off then..
any reason that wouldn't work?
People have used turn signal realys with some success even.
It seems like you need either no heat, some heat, or lots of heat.
If it works for you, use it!
