Thanks in advance! I have 2 storage tanks, each with it's own aquastat and pump, through a motor starter with "Hand, Off, Auto" selector switches. I also have a selectable "Transfer" switch (3 position) 1-2, off, 2-1. I also have 2 actuators to prevent unwanted flow to either tank. The transfer switch overrides any other mode. Aquastat 1 has priority over aquastat 2. Only 1 pump can run at a time, and only 1 actuator can be open at a time If aquastat 1 calls for heat it will energize actuator 1. The end switch of actuator 1 will then enable pump 1. If aquastat 2 calls for heat, it will energize actuator 2, but only if actuator 1 is not calling for heat. If Transfer 1-2 is selected, actuator 2 is energized. Then actuator 2 end switch will enable pump 1. If Transfer 2-1 is selected, actuator 1 is energized. Then actuator 1 end switch will enable pump 2. Any words of wisdom are welcome! AttachmentWard Chemical.pdf (420 Downloads) |
