I have a customer who has both a VS pump and a Polaris booster pump connected to an Intermatic P135ME timer. She has removed the Polaris cleaner from her system in favor of a robot. Now that she's removed the cleaner, she says when she tries to run her system, the booster pump "sounds like it's gonna blow up." Is there a way to disable the booster pump within the settings of the timer, or does the booster pump need to be completely disconnected from power?
