4. At one minute prior to the end of the timing sequence, the red LED will begin to flash continuously for the last minute of operation. The blue locator ring will then illuminate once the light source or appliance has gone off.
[DOH!] RTFM [/DOH!]
The instructions are pretty poorly written and, as I said, it's not totally clear whether that above statement applies to slaves as well as the master. The S/L connection between master and slave in their diagram is labelled:
*Optional wire for blue indicator ring on push button slaves only
However, I find this a bit ambiguous. Does it mean that this S/L connection is required (for indicator ring) only on push-button slaves, OR does it mean that is is
only "optional" in the case of push-button slaves?
Furthermore, the OP has indicated that he has touch, rather than push-button, switches. If that applies to his slave as well as master (are they actually the same thing, I wonder?), I'm not sure what that would mean in terms of attempted interpretation of the above statement about the optional SL for push-button slaves!
Given the point you raised, I'm also a little surprised that the instructions do not include a statement than an earth is not required, or even that an earth should not be connected (albeit, how?!) to the switch.
All-in-all, IMO not the world's best instructions!
