jokefox:
so like,if the time now is equal to the time the pump turns on (minus an hour) the circulation pump turns on
if the time now is equal to the time the pump turns off (plus 30 min) then the circulation pump turns off
It appears that three of your "pump on" times (for the water pump) are one minute apart. So, when should your circulation pump turn on and off? Work this out on paper and you might see a problem.
