Eberspatcher wiring problem

[clyst]

Hi All

Been trying to wire in a new (second hand) unit . It came with a rheostat switch but I want to wire it in to the existing room stat . So far so good but problem now is the good book says a "GREY" wire from the unit should be connected to the "BLACK" on the room stat . "GREY" wire is missing from the loom from main unit as the good book says the "GREY" isnt used on the redundant rheostat anyone know where the "GREY" should be connected to the heater unit ?? If that makes sense.

Cheers

Eberspacher is one of the better manufacturers - most manuals are available free online, and they include wiring diagrams which will help you.

Units purchased on eBay often come from specific lorry installations and plug directly into the lorry's control unit. On those versions wires like grey and even yellow often are missing and the units cannot function with standard timers and rheostats.

I'v down loaded the Espar manual but the wire colour abreviations are unreadable even on the comp screen !! Unbl**dy believable !! Checked other sites with same results

But if I can find which conn the "grey" should be connected to on the unit then surely its a simple case of running a new wire is it not that simple .

The wire colours are readable on my screen. Which manual have you downloaded? And from which site? The Eberspacher UK site has most of the manuals.

But it doesn't seem to cover the D1LC, which the OP has...

Thanks according to list :-"12 Grey External temperature sensor input, (optional extra, usually not used) "

Presume this is for truck installation or is it "room temp inut" ??

This is developing into a nightmare!! I thought this fitting was going to be a 5minute job !!

Well, so it does, my apologies. However, it has no wiring diagrams, merely referring to the loom colours and, as the OP mentioned, his loom doesn't have a grey wire. So it wouldn't really help him.

Sorry pvb. As can be seen from diag the black from the room stat is conn to grey in the main harness . The rheostat as shown on the page and in reality shows grey not used ie not fitted . What I now need to do is run a new "grey" from the room stat back to the heater unit . What I trying to establish is where should the "grey" wire connect on the heater unit .

Did you look at the link I gave you in post #9? That manual has detailed wiring diagrams, with pin numbers for the connectors. I'm not sure what else you need, unless you want someone to come and do it for you.

You didn't ask for that! In post #5, you wanted to know which connection on the heater the grey wire goes to, so you can run a new wire. The answer's in the wiring diagram, surely?

according to http://www.letonkinoisvarnish.co.uk/D2_D4_Service_1.html (nb its not my web site - just a useful one i stumbeld across) on the wiring page the grey wire for a DILC
is connected to pin 8 :
'08 Grey External temperature sensor input, (optional extra, usually not used)'



Depending on your installation you may or may not have to use it - i fitted a D4 to my boat in the aft locker. Because the locker warms up because both the exhaust and ducting go through it the D4 unit 'shut down' early because temp is reached.
