UH1 system - PRT-W replaced with Slimline-RF but it dopesn't pair

We have a UH1 system and I smashed one of our PRT-W thermostats (it fell off the wall when I was trying to change the battery!). I have bought a new thermostat but it is a Slimline-RF. They look the same but when I pair them with the same settings as the old one it doesn't work. Can anyone help please?

The Slimline-RF aren't the same as the PRT-W.  They look the same, but aren't compatible with the PRT-W receiver you will have. 

If you can call our sales team on 01254 669090 they will be able to assist.
