Notification on specific time

Dear all,
does anyone know how I can configure a host so that notifications are only sent every hour, for when the state changes from OK to DOWN and 5 min when changing from DOWN to OK?
I have this setup but not working:

    normal_check_interval   60
    retry_check_interval    15
    max_check_attempts      5
    notification_interval   240
    notification_period     24x7
    notification_options    d,u,r

In my nagios.cfg the interval_length=60

Thans in advanced.

notification interval 240 is every 4 hours… i’m not sure if you can limit escalations to a particular state change… but it could work.

from down to OK there wuill be only a single notification.
