Greetings Experts
I recently bought a nice powerful (hopefully) extractor with humidistat to remove steam from the bathroom.
The fan is a Manrose MF100 and the humidistat is a Manrose 1361. The old extractor was weedy and operated on a pull cord switch (no timer or humidistat), so got left on for extended periods and is now very quiet and still.
I've tried to connect the new extractor and humidistat but they're not working as I'd expect so am looking for someone with some experience to advise if the electrical connections I've made are correct. I've used the pull cord switch which operated the old extractor.
Here's the wiring diagram which came with the humidistat:
The wiring diagram for the extractor:
Inside the pull cord switch the wiring looks like this:
This is the existing switch which operated the old fan. I don't see any reason to change anything in this switch so have left it as is. So I guess the live (black wire) and neutral (grey wire) are switched. What would the brown wire in the crimp joint be for?
Inside the humidistat I've connected:
the black wire to the terminal inside the humidistat labelled "Switched live",
the grey wire to the terminal labelled "Mains Neutral", and
the brown wire to the terminal labelled "Mains Live"
Here's a photo:
Finally I've used a 2 core and earth cable to connect the extractor to the "Fan Live" and "Fan Neutral" terminals.
The Problem:
When I switch the switch on, the extractor comes on and stays on. It remains on even if I set the humidity setpoint to maximum and the timer to minimum. This evening it ran for more than an hour with the setpoint at about 95% and the run-on timer at 1 minute. I'd be surprised if the humidity in the room is really above 95%, so would expect it to run for no more than a minute.
Have I connected anything incorrectly or should I suspect the humidity sensor of being faulty?
Many thanks
