I installed a Stenner acid pump with a Sense & Dispense system from Goldline. There is a 2 hour timeout feature that will stop the acid pump from dispensing acid if the target pH is not met. When there is a call for acid, the acid pump will only run for about 8 seconds and then shuts off and will then cycle back on about 30 seconds later and then repeat this cycle. Is this the way this system is supposed to work? I thought the controller was supposed to run the acid pump continuously until the acid demand was met and then shut off and not cycle on/off.
