Help new xpelair fan installed - it not workie!

[jtp]

Hi all - new to the forum, so please bear with me if I'm posting in the wrong place.

Just had complete new bathroom refit, and installed an xpelair LVCF20tDC fan (low volate, condensation control, boost pull cord & timer).

The humidity sensor is not cutting in at all (despite long showers by teenage daughter!), and also the integral pullcord boost override is operating as an on off switch as opposed to a boost.

Installer is coming back on tuesday, and unfortunately he has never installed this fan before which is probably part of the problem. so I'm up to speed on the potential problems here - which I assume are something to do with a) wiring, and possibly b) incorrect setting ofhumidity sensor - can anyone throw any light on what it is that needs changed/and or fixed here?

cheers,
jtp

First guess....... No permanent live supply - everything trying to run off the switched live supply.

The LVCF20tDC is a 12v SELV fan, isn't it?

Looking at the installation info I hope he installed 3-core cable between the transformer and the fan?

There are options for delayed start and trickle operation so it will depend on the option switch settings.

There are indicator lights that should show that there is power etc. Its all in the installation & user documentation.

Thanks for the replies, which make absolute sense. have looked at the wiring diagram, and understand where things have gone wrong. In hindisght letting the sparkies fire ahead without any reference to the wiring diagram may not have been the best thing to do!

thanks again, much appreciaed.
