Seiko mantle clock (switchable chimes)

Question

I just got this clock that switches from westminster to whittington chimes. I used the information I read on this site to set the chimes. now I'd like to know how to turn the chimes off during the night and also how to stop it chimeing every 15 minutes and just have it chime on the hour. Do you know what time the chimes are supposed to stop and then restart in the mornings? any advice appreciated.
