Hi,
Was looking to replace my central heating timer with a TimeGuard NTT04. Had a look yesterday and the wiring is different than my old timer.
The new timer has 4 connections - L, N, S In, S out.
Wiring diagram -
230V 50Hz Mains Supply:
Live (Brown or Red) to L
Fit a ‘Link’ or ‘Bridge’ between L & S IN
Neutral (Blue or Black) to N
Load:
Switch Live (Brown or Red) to S OUT Neutral (Blue or Black) to N
Full manual here: http://www.timeguard.com/media/2566/NTT03_NTT04_Instructs_120x60_issue3.pdf
From my old timer I have:
2 x Red
1 x Black
1 x Blue
1 Yellow
Image attached.
The S In and S Out has confused me. Any help on how I should wire this would be appreciated.
Thanks,
S
