Help with the basics

Hi, I need some help with the basics of my pulsa coil A class. First some details.

I am on an economy 7 rate.

There are two switches on the wall, one off peak, the other on peak,

There is also a clock timer on the wall with 3 setting 1. on 2. Timer and 3 off.

On the boiler there is an on/off switch for the control circuit power supply.

On the boiler there is also an on peak boost function.

My questions are:

On the night rate which switches and settings should I have on

On the day rate which switches and settings should I have on

I've read the instructions from Gledhill but I still don't understand them. Any pointers and a general overview would be really appreciated.

Thanks,
James

Leave all switches on.
The boost will not work unless you press the boost button.
Also the other switch / timer you mentioned is it a " newlec"?
