FAQs
How many Isolators will I need for two controllers?
You'll need one Isolator for each controller you have in the system. If you have two controllers, you'll need two Isolators.
Does Isolator come with a warranty?
Yes. Isolator is backed by 1 year full replacement warranty against defects.
Is Isolator waterproof?
No. If your controllers are installed outdoors, we recommend you install Isolator along with the controller in a waterproof enclosure.
Can I use Isolator with a Rachio Controller if I don't have a master valve?
Yes, Isolator can still protect your controllers from interconnection issues. Isolator will still need to connect to the master valve and common terminals on your Rachio even if you don't have a master valve in your system. This is how your Isolators will get the power they need. Make sure you turn the master valve option to 'ON' in your Rachio settings.
