Reply With QuoteWah ! You can't wait already and bought the termostat.
Take a picture of the thermostat sticker and post it here.
I managed to get a friend to buy the external probe for me & it is a similiar model to this pic... But I just wanted to ask where does the wire circled in Red go?
1) The bigger circle on the extreme right (The one with the Red & Black wire) where does this connect to? I do suspect this is the Temp Probe...
2) The smaller circle looks like the thicker white wire (Below the Blue & Brown wire) is also somehow connected to the 02 Green wires via the wire connector...
Or is it the blue wire from the thicker white wire is connected to something? (Can tell that the wire is connected there because of the wire connector in the middle of the 02 red circles I drew) What is this connected to?
But it also looks like the Blue wire from the top of the picture (I assume this is the Neutral position at the starting point of the blue wire, if I'm not wrong this is the Wall socket) is connected to the wire connector as well? And if this wire is connected to the wire connector what does this blue wire connect to? I can't see clearly what wire it connects to onto the wire connector...
I also wanted to inform everyone I would have liked to ask the person who posted this but unfortunately this is a Chinese website & my chinese is not that good...
On top of that even though I signed up to the website I still cannot log in (I do not know why)...
I hope someone can help me as I really want to wire this up when I'm back...

Wah ! You can't wait already and bought the termostat.

1)yes, they're connected to the temp probe.
2) the thick white wire, which connected to the power socket, consists of three wires: L, N and E. The green/yellow wire, which is the earth wire, is directly connected to the above socket through the middle wire connector.... the blue and brown pair wires from the thick white wire are connected to 2 pair wires: the 2 green wires pair and the blue and brown wires pair in the black wire tube..... normally blue wire is used for neutral line but a green/yellow wire used for earth line. it's not correct in the pic.
Hehehe beh lun mah...Originally Posted by neon
Anyway I will only be picking this when I'm back in Macau... I will take pic then post but the design should look exactly like this one...

Thanks for the reply but can I confirm is the usage of the wiring wrong or it's just the colour of the wire is wrong?
Notice that you bought the wall mount flat socket instead of a block type socket. I used the latter one as the wires are not expose , simply drilled a small hole on the big casing and slot in the wire through the block socket.
What is the brand and model of your thermostat ? Cost ? Where do you buy it ?
Take note of the sensor/probe. Go for the thermostat which you can easily get spare part and does not cost a bomb . I am using Fox 1004 and the local supplier does not carry the spare part but managed to convince them to bring in few pieces for me $25 a piece, which I think it is reasonable . So I kiasu a bit and bought 3 pieces , as I have 2 pieces of Fox thermostat. My sensor/probe is plastic type and was cracked after 2 years usage (a lot of people say it is quite normal for wear-and-tear ).
Cheers
Bro,,
I've not collected mine yet lah... I got a friend to buy one for me... That is a pic of someone else's one lah...
I wanted to ask what do you mean by wall type & block type?
I thought the one that I suspect you are talking about is just the wall type with a casing... Is this what you are talking about?
I dun know what brand it is but I got my friend to buy the STC 8080... Price is cheaper than Singapore but not nice to post...
I told my friend to buy the sensor probe as well but I did not specifiy any specific one as I dun know what they have...
Bro Neon,
My friend bought me the STC-8090... Here is a pic of the wiring diagram... Can you tell me what is connected to what? Thanks
1. Live wire
2. Mutral wire
3/4 probe. Don't know which is +/-
5. Not connected
6/7 9/10 Normally open
7/8 10/11 Normally close
My friend gave me the External Temp Controller this morning... Here is a picture of it in English (Thank God!!!)
Maybe this would be easier for anyone to help me...
Stephen,
What do you mean by Live & Neutral?
Does it mean that I need to plug a socket to the mains & wire the Live & Neutral to these 02 points? (Sorry I've not tried this before)
And what do you mean by Normally Open & Closed?
Can anyone advise me which is the +ve & -ve for the probe?
The wall power socket have Live and Neutral. You connect your power cable here. Can't remember the color coding.
Normally Open & Closed is for the relay, use to turn on or turn off your chiller or whatever you want to connecting it onto. Open means when there is no power it is open circuit or no contact. Close mean when there is no power both pins are connected.
You might want to take photo of your sensor as well. If it is resistive type then +/- does not make any different

ok...for 3 pin
Gorund : Green & Yellow or Green
Live : Brown or Red
Neutral : Blue or Black
Live and Neutral is from the power cord that will be connected to the power point.
I am not sure NTC sensor means..Some sensor is resistive and some is diode..like PT100.
Thanks...
The NTC sensor is the temp probe that came with the gadget...
So how do you connect the chiller to this?
I always see that people will add a socket to this... So the chiller is plugged into this?
So we will only need to 06 points?
So point 10 & 11 I assume is for the chiller to be plugged in... Which wire is supposed to be wired into which point?
Anyway this a pic of the sensor probe...
Well, since the sensor comes with the controller then I think there is not +/-.
I am not an electrician. So, I would not advise about the electrical connection. You are should seek advise from a license eletrician.
I managed to find out the wiring from a friend... I will post the results after I make sure it's working...
Bro Neon,
Can you shed some light on the subject of the relay? I was thinking of linking it as well...
Use a contacter if you can..
Stephen,
What is a contacter? Sorry I dun understand...
Is works very similar to a relay but more heavier duty..

The sensor probe white cable to point 3 and red to , should work.
What is the relay you are talking about ?
I decided to wire it the way I feel it should be... As per the Hong Kong website that I went to in the first place...
Can anyone tell me if this is wrong? Thanks...
If someone can verify this, it would be easier for others to wire the External Temp Controller in the future...
I prefer not to burn my house down& do it the correct way...
Just to make sure everyone understands...
The wires the Red arrows that are pointing to are connected to the main socket (Power Point)
The wires the Blue arrows that are pointing to are Live wires that are connected to the STC-8090 & to the Chiller when it is plugged in...
Just wanted to add that the Brown Wires (Live) that the Blue arrows are pointing to are connected to points 9 & 10 on the STC-8090...
From what I understand the circuit is not complete & will only complete when the temp is above the required temp set... Which will complete the circuit powering up the Chiller...
The white arrow shows the incomplete circuit...
