Help on wiring - Replacing Drayton RTS2 with ESRPT4 from ESIControls

[Andrew Michael Lloyd]

All,

Your help would be really appreciated!! Am trying to replace my Drayton RTS2 with an ESRPT4 but cannot work out which wire goes where! I've taken a picture of existing wiring and the useless manual from the new thermostat. If someone could just tell me in lamen terms I.e. Red wire to Pin 1 etc that would be great. Thanks in advance. This is connecting to a combination boiler - Worcester 24CDi

Red wire to 2 and yellow wire to 3, make the blue (neutral) safe but not connected to anything.

Many thanks Picasso I'll give that a shot. So just tape up the Blue and Connect Red to 2 (Common) and Yellow to 3 (Normally open).
