I am designing a system to mist my outdoor air conditioning units during the summer. I will be powering a low voltage irrigation value using the low voltage from the AC controls - 24 VAC. I have 2 air conditioning units that work independently of each other. However, there will be times that both units come on at the same time.
How do ensure when both units come on at the same time that electricity is sent to the power power supply without shorting out the solenoid or shorting out the air conditioner power supplies?
