It might help if you said which timer you have. Does it have volts-free switching contacts (as if you'd know!)?

Danfoss Randall 103E7 with six terminals:

1 On
2
3 Com
4 Earth
5 N
6 L

1 and 2 connected to the thermostat.

2,3,4,5,6 go to the boiler......

You can see the instructions here.

The wiring is simple enough. L, N and E are connected to mains supply and the switched live from the boiler (terminal 3) goes to timer Com (3) and the timer ON (1) goes back to the boiler (4).

If you wire a thermostat in as well it goes in series between the boiler and timer, either between boiler 3 and timer 3 or timer 1 and boiler 4. Timer terminal 2 is spare and can be used to link in the room stat.
