cylinder thermostat

[quorum]

Hi guys,i need help with this wiring, i am replacing an old sunvic boiler thermostat with a newer sunvic,prob is the wiring from the old is 1 red 2 yellow 3 black but the wiring colour inside the new is 1 yellow 2 white 3 blue
do i just connect 1 red 2 yellow 3 black as the old was numbered and take no notice of the colour difference?

Thanks pal, the new one is clearly marked but the old one has no markings other than 1 2 3 anyway my mate managed to locate same stat so prob solved but thankyou again mate.

You need to know which was common, call and satisfied on the old stat and transpose those wires to the relevant terminals on the new stat.
