Devices Supported on Secondary Attendant Controllers and Modules

Poolside Tech conveniently allows multiple Attendant controllers to be wired together to allow them to work as one unit.

This allows you the freedom to add more devices – like pumps, actuators, and lights – to a system that might’ve not had enough relays or other ports to connect them all.

However, not all devices types can be physically wired and controlled by what we call a “secondary” Attendant device.
