Inquiry (采购产品): Flow switch I do have a flow switch model Q 12DS-C2 made by Harrwill. There is only one wire coming out drom the flow switch, but it ends in a telephone jack to be inserted into the control panel. Please indicate which model and which option match my current switch. The control box indicates no flow, yet there is plenty of flow through the pipe. So, the problem may be the switch or the control panel. Please indicate if I can check whether the failure is due to the flow switch.
