Relay, wich one is what?

Hi guys,

On some SD models there are two similar relays, slightly to the left of the engine.
Just behind the fuel filter.
The rear one is the glow relay. What function has the other relay?

intake air temperature heater

Ah ok, but at what tempature does it kick in?

To be honest I had to read it over a couple of times.
Intake air heater to me sounds like the same job the glow plus are doing.
Or am I missing something her?
