I have a Worcester 24CDi RSF combi boiler and would like to fit a wireless thermostat to it. There is no thermostat or heating timer unit currently installed.
Here are the installation instructions for the boiler:

I have the Thermsave DRF 3 Wireless Thermostat that I would like to install (http://www.thermsaver.co.uk/heating...al-wireless-programmable-room-thermostat.html). The installation instructions for the thermostat are here http://www.thermsaver.co.uk/media/pdf/controls/thermsave-drf3-instalation-and-user-guide.pdf
Looking at the instructions for both the wiring (page 12 boiler and page 3 thermostat) seems not too complicated but I just want to make sure that I'm 100%.
On the boiler ST8 part we have connections Ns (Neutral), Ls (Live Switched), Lr (Live Remote??), Spare. On the receiver I have N (1), L (2), COM (3), NO (4) and NC (5). Can anyone tell me what NO and NC are for?
From reading articles on this and other forums I expect the wiring to be:
Ns -> N
Ls -> L
Lr -> COM
Presently there is a connection on the boiler between Ls and Lr. I believe that this should be removed and the connection should now be on the receiver between L and COM. Can anyone confirm this?
Any help greatly appreciated.
