Myson Apollo 625 DVI Boiler

I have a Myson Apollo 625 DVI boiler new in the box. From what I can tell it is a 15+ old unit. The instructions are not very clear regarding the circulation pump. I do not find much online regarding the division was sold by Myson in 2002. The instruction state it is a constant flow system. I am assuming that means the pump runs 24/7 and is in no way connect to the boiler? Can I power the pump to a simple light switch to allow on and off control? Any assistance would be appreciated.
