I recently purchased an Exo-Terra Monsoon RS 400. for the first week or so it ran fine. Now it will continue to cycle at one to two second sprays every 15-20 seconds reguardless where the cycle and duration knobs are set. Is there a way to reset the cycle and duration. So far i am not impressed with this equipment. I hope that i am doing something wrong and someone can assist me with this delimma. Thanks for any assistance
