Spare wires swapping out Honeywell ST699

Options

Hi,

I am preparing the wiring to swap over my Honeywell ST699 timer for the tado extension. The instructions asks if there are any bridges which I believe there are 2: 8 COM to 5 COM and also 5 COM to LIVE.

The suggested wiring was then:

N - N

L - L

CH COM - Nothing

CH NC - Possible 4

CH NO - 3

HW COM - Nothing

HW NC - Possible 7

HW NO - 6

<symbol> - Nothing

P1 - Nothing

P2 - Nothing


This would leave spare wires from Honeywell's 5 (CH COM) and 8 (HW COM). What should I do? Any help much appreciated - I am cold :)
