A Little VC10derness

I have a question regarding the duct temperature gauge on the EO's Anti-Ice panel (the top one).
I know that it reads ambient temperature with engines off. But, with say only one, two or three engines does it show a proportionately lower temperature than if all four engines are feeding into the system?

Hope somebody can remember!

Air being bled off the engine for TAI purposes is temperature controlled to 210 to 230 Degs C by mixing LP & HP compressor bleed air. So providing an engine has an air supply with a temp in excess of 210 - 230 degs, that is what you will get in the duct no matter how many engines are running.

Thanks for that.
