Have an aerator (freshwater intake) pump and recirc pump installed. Do I want or need a timer switch for both pumps? or do they make one switch console that will take care of both independently?
operate your pumps with on/off/on switches.... up/on of both switches would connect each pump to battery positive for constant operation... center/off would be off duh...... down/on would connect to the switched positive from your timer module for automatic operation... you can thus use either or both on or off the timer at any time.
