I recently had a warranty claim where the service guy came out and replaced the LCD screen on my VS pump, which is a spa booster pump in my setup (the main pump is the VF pump). Prior to that, if I pushed Spa on the EasyTouch panel or remote the VS pump would turn on. Ever since the service guy was here, neither the panel nor the remote will control the pump. When I push "Status" in Settings it says "No Comm". I have to use the controls on the pump to control it. The rest of the equipment works just fine and can be controlled by the panel or remote. Any ideas? Thank you in advance.
