Can I simply replace my mechanical stat with a wireless stat? Dont want to touch the boiler so was planning on installing the receiver where the existing stat is. Question is can I do this as my existing stat only has 3 wires (as follows) and the wireless receiver needs 4 wires! Is it possible to use the one live wire from the old stat to feed the 2 live contacts on the new receiver?
Old - New
Live - Live and common
Switched live - Call for heat

If I cannot do this I will simply use a wired programmable stat. Any advice gratefully received.
