Here is schematic diagram of Gib thermostat hygrostat. What I want to do, is connect fan ventilate my grow room when temperature raise over 25C/77F and connect my ultra sonic humidifier on when humidity drops under 50%. Unlucky for me, I dont understand this schematic. Wich line goes where?



We use 230V AC in here.

Do I connect fan L to the number 3 and humidifier L to number 6? But how I connect fan N and humidifier N? To the wich number? Or do I pull new N line from wall plug for the fan N and humidifier N?

Please help old slow thinking pot head.

Electrician work isnt for me, but in here (damn near russia), we pot heads are popular as child molesters. Thats why I cant ask professional help. I have to be electrician, constructor worker, plumber and ventilation specialist.

I'll get the answer for you tomorrow. My friend is an electrician and staying at my house which i don't live there yet but I'll be there tomorrow working he'll know

Hey, I'm attempting to check out the diagram, unfornately my small screen is not good for zooming...is there a way you can put that photo up as an attachment?

It appears that there is a switch on pin 5. the rectangles at the right are likely resistors or a "load" but i cannot be sure. pins 2, 5, 1, 9, and 7 are all connected together. i know this because there is a dot over the crossing of the lines. if there is no dot over where two lines cross then you can assume the lines do not touch but are only crossing to compact the drawing. more to come im answering and typing at the same time

so 2 is a sensor controlled switch.

5 is a push button switch.

and 7 is a sensor switch of sorts.

the L for Live is the Hot wire in the US for anyone who cares.

The white wire on an AC line is neutral and the black is LIVE or HOT. this means you can hold the neutral wire connected to the plug in the wall and not pass any voltage between you and ground. but if you were to hold the LIVE wire you would be a load on the circuit the power company sees and that will leave a nice burn.

so careful of course

is it stated anywhere that you need two power supplies? i would say that it means you can hook it up to either a 230v supply and if so use pin 4 as neutral but if you use 24v then use pin 8 as neutral. in either case use 5 for LIVE and 1 and 9 for LIVE as an extra output in case you need it for powering devices.

2 and 3 actually look like they are one or the other cases. and same goes with 6 and 7.

where are we at now?

The thing I'm wondering is that the Line that goes to pins 1 and 9 look like they have some sort of asterisk on them...as in a photo of the entire page would be useful

probably indicating not to actually attach the LIVE to that part but that those are outputs to deliver LIVE once you have attached it to 5. you can see by the wire crossing that they are actually the same point.

Also wondering if the sensor is built into the controller or if it is an external sensor...almost seems as if pins 8 and 9 are incoming low voltage from an external sensor somewhere. Pin 6 tells your humidifier to turn on when humidity is too low, pin 7 tells your dehumidifier to turn on when humidity is too high...

So my guess would be 1 and 4 are your incoming Line voltage, pin 5 would be your outgoing 'load' to an external sensor somewhere...2 and 3 I can't really see the picture well enough...is that a light and a fan?

'LIVE' just means the wire is hot, it doesn't indicate whether it's from the source (LINE) or if it's heading somewhere else downstream (LOAD) so actually 'LIVE' just means 'hot wire.' It doesn't indicate whether it's source voltage or heading towards device...hence it actually mattering what the little symbol next to L on pins 1 and 9 mean, instead of just throwing 'probablys' around

i mean you could very well be right. neither one of us knows exactly obviously. the resistor would indicate there is some kind of load between the supply and the actually desired circuit.
