AS1093KT - Intermittent Windscreen Wiper Controller

Hi.
I’m interested in fitting this controller to a boat windscreen wiper motor which currently is just either on or off. Sorry if this is a simple question, but, does the switch on this controller allow continuous operation, as well as intermittent, of the windscreen wiper? And does it have an ‘off’ position?
Thanks

Sorry, this kit from Quasar electronics is not a Velleman Kit.
