Boiler control

[skip11]

Hi looking for advice I have a greenstar he boiler and potterton controller. My problem is the sliders on the front of the current controller have broken off and I need to replace them but I can’t buy the Potterton controller any more. I’m looking for a suitable replacement? Also it doesn’t control the hot water separately the hot water only comes on when the heating is on. I have attached photos to this thread of the boiler and the controller.

Did you ever have independant control over central heating and domestic hot water ??

Potterton EP2. Direct replacement onto same backplate and can be set up for linked or independent control depending on your system.

I’m not sure what you mean by independent control? It’s always been the Potterton controller that has been used for the heating only to set the times to come on and off.

Were you ever able to set domestic hot water to come on without central heating ,or c/ heating to come on without also heating water ??
