If you do not have Drip Detect™ enabled, the Control will run a monthly valve check by closing and reopening the valve on the first day of every month at 4:00AM. This ensures that the valve is always working properly and that sediment is not causing the valve to lock.
Like with Drip Detect™, the Control will not open the valve to conduct the Monthly Valve Check if the valve is already closed. It will also postpone the check for an hour if the Control senses that water is running during the check. Note that the Control must be calibrated to run the Monthly Valve Check.
