The Pool Pilot ORP Relay Kit allows you to connect to a Rola-chem automated controller. Rola-chem controllers do not have a dry contact ORP signal to make it completely compatible with Pool Pilot DIG-220 Salt System. The Relay Kit has the standard 110 volt pigtail that plugs into the Rola-Chem controller. In the relay kit, there are two cables with the correct molded connector that plugs into the bottom of the DIG-220. In this configuration, the DIG will be set on 0% output and when the Rola-Chem calls for ORP FEED, the DIG will display ON and activate the cell.
Note: The second cable on the relay kit will not need to be used and can remain rolled up and tie-wrapped.
