Replacing a Randall 4033 programmer

Hi
Currently our CH and HW is controlled by a Randall 4033 unit.
I have recently ordered a Drayton Tempus 7 as a replacement.

Does anyone know where I can find a wiring diagram so I can carry out the replacement?

many thanks......

Diagram for Tempus should be in the box.

Hiya
The wiring for the tempus is fine, its the Randall 4033 I need the diagram for to do the conversion.

Thanks

Found the following from an earlier post:-

Randall 4033
1 L
2 ch on
3 ch off
4 hw on
5 hw off
6 L (link to 1)
7 N
8 E

current wiring to Randall unit is as follows:
One main query, one cable connects to pins 6, 7, 8 therefore supply cable.
Another cable connects to 2, 4, 5.
There is no connection to terminal 3??!! - any ideas as to why I haven't got any connection to this terminal? - the programmer in its current state appears to be working correctly?

thanks
