Hello,
We have three 200kw pumps on our roof plant room which have recently had new inverters installed. The inverters aren\'t responding to our building management system. The inverters, installed and commissioned by company A, aren\'t responding to the commands issued to them by the kit installed by company B, which in turn works in conjunction with kit installed by company C.
So, three different companies, need all three to attend at the same time. I want to send an email to all three, ie. not CC\'d in, or separate emails, one email to all.
I didn\'t find the right solution from the internet.
