In Line Fan Wiring Advice Needed

[floydmeddler]

So... turns out that L1 is low speed and L2 is high speed. Which kinda makes sense actually when you think about it...

The blank isn't removable.

So powerful. I think it's going to do the job nicely

Are you going to hard wire high or make it switchable. Just wondered how noisy it might be.

Plan was to wire on high only. However, after seeing how powerful it is, I'd like to switch between the two. Reckon i'd only need high for the boil. Sparging and hop stand should be fine with low.

I've had a quick look at 2 speed fan switches and feeeeeck! Pretty pricey!

Is there a cheaper switch option out there?

[floydmeddler]

Would this work?

Although it doesn't have an 'off' option.

Maybe this? Good up to 16a apparently!

To answer your question yes they would both work.

But IMO This is the easiest and cheapest.

One for on /off then next one for speed.

Really? How would you wire it?

if you dont need on off a standard 2 way light switch will do,if you also want off and on but don't mind 2 switches https://www.screwfix.com/p/10ax-2-gang- ... hite/7549d

Really? How would you wire it?

live in to switch 1common ,terminal 1 or 2 on switch 1 linked to common of switch 2,terminal 1 of switch 2 to the slow speed on fan ,switch 2 terminal 2 to high speed on fan.neutral goes straight to fan

[MashBag]

You need two switches.

Switch One to do the on-off. Live in. Live out. (leaving one terminal unused).

The 'out' from that is the 'in' to switch 2. (you need to add this bit of wire as a bridge)

Switch 2 live in (your bit of wire) connect to L1 or L2.

Bingo.

[MashBag]

Bit late there. What we both said.

[floydmeddler]

Haha. I love it when two plans come together!

Thanks fellas. Super advice!!

[floydmeddler]

Gents,

Does this diagram look correct to you?

Thanks

[MashBag]

Yup.

Was tempted by, no you have "fast" and "slow" wrong way round

[floydmeddler]

Cheers! Works a treat. I've re jigged the wires so that left switch is on/off. 'On' function on right switch for high fan. 'Off' function for low. Just made sense in my head that way.

Getting there slowly. Next jobs:
Frame for the vessels
Hot water supply, sink and drainage
R.O system installation
More OSB wall panels
Spot lights
More things that I've forgotten I'm sure!

This is going to take a while...

It will be worth it.
