[wonadoomore]

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
