I am looking for someone to design a valve controller.
Here is what it will accomplish
12 volt power will be supplied to it via the car battery (always on) the ignition switch (only on when the ignition switch is in the on position).
The controller will receive 12v from the battery and ignition. Power will be supplied to LED #1. Thermostat will receive 12v also.
Once the thermostat passes the 12v back to the controller, the valves will receive 12v. (opening the valves). Power will then be supplied to LED #3 and removed from LED #1.
When a button is pushed the controller will remove 12v from the supply valve (closing it) and at the same time activate a timer. Power will also be supplied to LED #2 and removed from LED #3.
When the timer reaches zero the controller will remove 12v from the return valve and LED #2. Power will then be supplied to LED #1.
If the 12 volts from the ignition switch is removed without the button being pushed the controller will send 12v to signaler . Once 12v is supplied from the ignition again the 12v to the signaler will stop. The button will be pushed and the "End process” will start.
The controller should fit in a plastic box approx 4"x3"x1"
I am looking for two things
1. A schematic for this controller
2. A built and working unit

I can do the project in 15days. I have downloaded the jpg file for understanding purpose! The design will include a schematic diagram and a complete working pcb!
Hello What about Pic12 [url removed, login to view] seems it would match the [url removed, login to view] the way what is the termostat output - switch or analogous? Beat regards
I have 8yrs exp in circuit designing. I can make the schematic diagram and PCB with clearly and perfectly using Multisim and Express PCB [url removed, login to view] can see your project demo(video) in advance.
We have much experience in the design of various temperature controllers, Process automation and PID Controllers. We are a leading Embedded technology solution provider. So its a simple product to be handled.
Despite of all what you have mention about the project,I would now like to ask from you,as in how many hours do you want to have this project, rather than counting it in days! It hardly requires few hour of working.
Hi, I will definetly do the job as specified by you. but the duration of the timer is not mentioned. what will be the initial time when it sarts timer. thanks Ashok K
