F.A.O Anyone Who Can Explain This To Me

[DIY22DISASTER]

D.Hailsham has been very kindly helping me out with a dilema of mine.

Unfortunately I need one last question answering but sadly he is not online at the moment, and I am kind of stuck in limbo.

Would you be kind enough to answer this question for me ?

"What does the highlighted quote at the bottom of the page mean" ?

Disconnect everything from the junction box including links between terminals and wire up as follows:

JB = Junction Box

Mains Input
Live : JB 1
Neutral: JB 2
Earth: JB 3

Tempus 1
Live: JB 1
Neutral: JB 2
1 Com: Link to Live in the Tempus 1
2 Off: JB 7
3 On : JB 6

HW Thermostat
C: JB 6
1: JB 8
2: JB 7

Digistat
Link JB 1 to JB 4
C: JB 4
On: JB 5

Honeywell Valve
White: JB 5
Grey: JB 7
Blue: JB 2
Green/Yellow: JB 3
Orange: JB 8

Pump
Live: JB 9
Neutral: JB 2
Earth: JB 3

Note: the Pump gets its Live connection from the Boiler PL terminal via JB 9. This in accordance with mfr instructions.

Boiler
Live: JB 1
Neutral: JB 2
Earth: JB 3
Link JB 8 to JB 10
Switched Live (SL): JB 10
Pump Live (PL): JB 9

Many thanks

the pump is wired in from the boiler to allow for pump overrun instead of via the wiring centre

Thanks MGHeat,

So I need to run an extra 2 core cable from the boiler to the Junction Box and make the necessary connections ?

Make it 2 core and earth or three core flex. 5 core cable would be a lot tidier.
