Discovery 4 timed climate control

For the last few days my car has been comfortably warm when I have got in to it on some cold and dark mornings.


Last weekend I enabled the timed climate control (park heater) feature which is available on some models of the Discovery 4.


This starts the Fuel Burning Heater (FBH) at a pre-set time each day and runs it for 30 minutes to warm up the coolant. In mine it also starts the blowers to warm up the inside of the car.

Based on posts on Facebook, many people do not get the blowers, just the FBH, when they set the time. I have no idea what triggers the blowers to work as well.


Mine definitely starts the climate control inside the car. The temperature 'Auto' light on the dash is flashing, as seen in the following, short, video clip.





Another option is to install a remote control to start the FBH as required. That sounds like a good idea but the timed solution works for me and is just a software feature to enable.


I used an IIDTool to enable a couple of the built in options. I had previously enabled the 4x4 info display so knew roughly what process to expect.


Oddly, whenever I enable features with the IIDTool, it always finishes with 'failed'. Despite that discouraging message, it has still done whatever I had asked for.


I am very happy with the timed climate control. We'll see how well it works as the weather gets colder.
