Fox Temperature Controller

[hkching]

I just bought a Fox Temperature Controller. But the instructions not very clear.

Anyone can show a pic on how to connect the thing up?

Another question. I'm thinking of using it to control my 2x250W MH. But they are now on separated 3 pin plugs. What's the best way to get both of them controlled by the FOX Controller? I'm a electronic dummy

Thanks in advance for your help.

Quite easy actually:

1 and 2 goes to your temperature probe.

9 and 10 goes to the live wire of your device

11 and 12 is the power supply for the controller.

Simple?

If i'm not wrong;

9: is a normally close contact

10: is a normally open contact

Cedric pls verify

thank you

Thanks bros for your help.

So I do not need to connect the earth wire to the device? How to I ground my MH lights?

As for my second question,

Another question. I'm thinking of using it to control my 2x250W MH. But they are now on separated 3 pin plugs. What's the best way to get both of them controlled by the FOX Controller?

Can I use a multi-point extension and insert the controller on the power cable going to the wall socket? Will it be dangerous? I will be able to control both my plugs using 1 FOX controller that way.

Pls advise. Thanks

I just checked my wiring for both my chiller (cooler function) and MH (HEater Function). Yes, its 9 and 10 for both so it is neither a normally open nor normally closed circuit.

Hope this helps!

You still have to do your Earth and neutral wire for your MH the normal way. Remember only the live wire for the device you wish to control goes to 9 and 10.

As for the multi point extension, once again use the simple calculation of P=VI and add a safety factor of 80% for normal usage and see if it goes beyond the limit of FOX-1004.

FOr the benefit of everybody who is asking me repeatedly and still will not do the calculation themselves:

P= VI

P= 230 x 3

P= 690w

Considering Safety Factor

80% of 690w is 552w.

Remember to account for the surge of your MH when firing up.

Hope this helps.

Got it bro...

Hi Bros,

Just tried to connect up my FOX controller just now.

As advised, I connected my device to port 9 and 10. But when the Output 'On' lights comes on, still no power goes to my device. Any idea? Actually I tried all ports, still can't.

Another question. Let say I want to have the following settings :

1. When Temp hits 30, power is cut off.

2. When Temp drops below 30, power will return after 5 mins.

How do I set this on the controller? I understand that there're 4 settings. I can only make out the following:

1. TYP (Type) = C

2. DLT (Time Delay) = 5 mins

How to set the rest? What's DIF (Temp deviation) and COR (Correction of Temp)?

Pls advise..

hkching,

I just checked my wiring for both my chiller (cooler function) and MH (HEater Function).

Thats where you went wrong, you should have set to H as you are using your MH to heat your water. Your time delay is correct.

Leave your COR alone unless you know how to calibrate your probe (quite simple actually, remember the triple point of water?).

For use of delta, see the this example for Heater Function:

Set Temp at 27

Delta at 1

At 28 power to device cut

At 26 power to device resume

hkching, your wiring is also wrong!!!

Remember only the live wire for the device you wish to control goes to 9 and 10.

Why is it blue and brown going to your 9 and 10??? Is your blue your live wire? If you understood my instruction, it should be brown in 9, brown out 10. Blue is never used. Remember, your controller does not supply power to your device. It merely acts as a switch.

Is this better? You got to follow instructions clearly and read carefully.

Thanks Cedric, I just managed to get it wired up correctly with the help of someone more experienced. Tested and it was ok..

I agree that with you that we should be careful while doing electrical stuff.

Hmmm.. I definitely will be reading up more...

Appreciate all your help bros...

Hi,

hkching, how much is this temp controller? and where to get this device? Thanks

Charlie

[Domino]

Is temperature probe delivered with the FOX controller? I intend to buy one too.

Thanks

[surfedelic]

Yes - there is a temp sensor which comes together with it.

[alanseah]

can show pic of the correct wiring.. which make it easier for all of us to understand..

thanx

for the answer. I'll get one when I have a chance.

This thread very useful.

Price for the device?

[hkching]

Price for the device is $85 at Sim Lim Tower.

Maybe Cedric help us by posting a pic of his connection.

I can also confirm if I did it correctly.

[zorden]

Until now still don have the right picture..??

ME scratching head liao...

not a technical student...never pay attention in school

need to set this FOX controller
