Room thermostat change

[blaggy]

Hi All, I am going to change my Honeywell T6360B thermostat with a Wickes thermostat.
I have a potterton Suprima standard boiler (not combi), motorised valve and cylinder stat.

The Honeywell stat is wired as follows
Pin 1 Red wire
Pin 2 Blue wire
Pin 3 Yellow wire
plus an earth wire

The Wickes stat has pins 1, 2 and 3 plus an earth.

What should go where???? can someone help please.
