Wiring a Danfosse 103 timer to a Danfosse RET 230P Thermostat?

I have a Sunier Duval SD 620 combi boiler and have a Danfosse 103 timer ~ old but reliable ~ Im fitting a Danfosse RET230P Room Thermostat.
1. Im confused by the wiring or lack of wiring instructions ... does the thermostat wire directly into the Timer and ignore the boiler altogether as I presume?
2. ON THE THERMOSTAT~ It says to bridge 'L' and COM/3 thats pretty clear but then what???
What other connections need to be made and to where?
Thanks
