RE: Status LED for Comfort ?

["Paul Gale" <groups@xxxxxxxxxxxxxxxx>]

I would think that the door locks are going to be too much for Comfort - I
have a couple but they're powered by separate PSU's rated at about 1A each.
Comfort simply switches the trigger in the PSU. The PSU's are specifically
designed for the door locks and have a battery backup facility if needed
(although I don't use this as my locks are fail-locked and have a high
security manual key override).

Paul.
