Hi
Yes the Honeywell programmer has the receiver inbuilt I'll let you know model when I get back
Cheers
The thermostat itself maybe wireless, but there will be a receiver somewhere that it communicates with that has the necessary wires connected to it.
It maybe that your existing Honeywell programmer / timer had the receiver inbuilt, if so that's fine as you are replacing it. However, I don't think this is likely. So, if you can tell us the make and model of the existing wireless thermostat we can advise further.
We knew that already as we can tell from the wiring. In fact, if you look at the page of the manual I posted you earlier you will see that it's headed Y Plan.
