We do not manufacture Potterton at Drayton, the Potterton EP2002 is a dual channel Hot Water and Heating, the LP111 is a Single Channel Programmer so this is no the right variant.
You will require the LP241 Dual Programmer which unfortunately is not a direct replacement, all the wiring terminals are the same, however you do not require the links between L-5.
