If after a minute of turning the unit on, your CircuPool RJ shows 10-15V and its voltage never increases past that point to the normal range of 20-30V, this means that the Control Module is being provided 120V power while being internally configured to accept 240V power (which is the default configuration). Until the unit is properly configured for power, it is not generating any chlorine and is idle. See pages 16-17 in the RJ manual for more information about wiring, and please reach out to customer support if you need additional guidance.
