Today I 'ave mostly been sorting a Fuel Burning Heater remote for my 07 Rangey Roverer.
I started by following
this idea, but without the wifi thing, which is where the trouble started, because I wasn't using what he used. The wiring was the same idea though, and I bought a cheap (less than a tenner off fleabay) remote relay. So it's a positive lead from the vehicle wiring to the + on the circuit board, with a connection to the 'com' terminal, earth to the - on the board, and a trigger wire from the 'no' connection to the vehicle loom.
At first it would only work if I kept my finger on the button, not ideal as that would lead to a sore finger and probably drain the remote battery in no time.
Then I found out that they need programming. There’s a small button on the circuit board, with 3 options; momentary (standard option – hence having to keep your finger on the button), toggle and latch. I used the latch option, one button on the remote for on, one for off.
This system is ideal for use at close range, if you need to operate the pre-heater whilst sat in an office then you’ll need a gsm system, and good look figuring that out. I used this video to suss it, now I need some nice bad weather to try it out for real.
