Sunvic TLX7501 on an Ideal RS40

[jenno]

Hi guys im new to this superb forum and before i tackle this job i thought id best ask for advice to save messing it up.

Im wanting to replace the rubbish Honeywell Dial Thermostat on my Ideal RS40 Central Heating System with a Sunvic TLX7501. Having looked at the current wiring it is as follows:

Red on Conn 1
Blue on Conn 2
Yellow on Conn 3

Any idea what goes where on my Sunvic ?

Cheers
Karl.

here you are
red to com (3)
yellow to on (2)

the blue is not needed so disconnect it in the wiring centre or put in a block and tape it
