Hi

I am currently making a pool heater and i have a comodated an old air con unit i have come to a point on the circuit board where i am stuck.

I am makeing a controler to send a signal to the outdoor heater but the out door heater has a 240v ac supplie and 1 live 12v DC signal cable. But there is only 1 nuteral for the ac and non for the DC.

I have an idea what board i need to make, I am just stumped with only 1 nuteral for AC and DC.

Help please
Thank you

Welcome to the PF.

We have a rule against dangerous discussions here, and with your lack of knowledge, it would not be a good idea for us to try to help you do this. Please find a local resource (EE, electrician, etc.) to help you with this project. Thread is closed.
