Old Expelair WX9 Fan

[AdrianUK]

Anybody know the correct wiring for the old (ie. mid 1970's) expelair WX9 in wall fans?

The fan connector has five terminals: E N L 2 3. I know this fan can be used as intake or extract and can be multi-speed. What connections should be used for a basic extract without a controller?

Thanks

Adrian

After a quick Google:

See fig.6 and
installation instruction 8

Thanks for the link.....this is the current WX9 model (which I've found)... but this is very different from the 1970s version. The current model seems to have a mode selection switch under the cover (fig 7 on your link), the 1970s version had a 5 pin "fan connector" on the top of the fan chassis and no switch. When used without a fan controller, the fan connector would contain wire links which configured for intake/extract & speed. This seems to have been replaced by the mode switch on the version you linked to.

Ah. Sorry I don't know - someone else might.

Is there no indication on the fan as to what 2 and 3 may do?

Alas, not. We do have several other WX9s at work, but connected to controllers, so if no-nobody here knows the answer I'll just have to open these up & see if the DVM will help me deduce the answer.

Thanks for trying to help. I did email Xeplair but, so far, they have not replied.

What did the makers say when you asked them?

Read the post immediately above yours.

You must mean the one that appeared while I was typing.

Is this the fan with the solenoid operated shutter

If so im sure for direct on line use, the supply goes to L for the solenoid, you should see the wire going from L to
the solenoid with a neutral.

You then have to link L to 2 or L to 3 depending on intake or extract, i dont recall which way round is which, N is neutral obviously.

Do NOT link terminals 2 to 3

For controller use the 5 wires, give a mains supply to L the solenoid, regardless of the motor direction, the controller then limits the supply to the number 2 or 3 contacts and N to regulate the speed.
Without the controler it runs at full speed.

Well that's just rude!
