Changing a Satchwell TL for Drayton Digist +3

SMP012 · 30 Jan 2011

Currently I have a dedicated gas boiler that is used for central heating only and programmed via Potterton EP 2000. The thermostat is a Satchwell (about 15 yrs old I think and the one I would like to replace).

If I was to switch the Potterton EP 2000 to constant and use the Drayton Digistat +3 to control the central heating would this wiring detailed below be correct, given my existing wiring set up:

wiring for the Drayton Digistat +3

RED Live to common

YELLOW Switched Live to Call for Heat

BLUE Neutral to a terminal block

Earth to another terminal block

Thanks. Steve
