Making electrical connection to thermostat contacts
 

I'm planning on using one of these thermostats:

to control the extractor fan in my bathroom. The idea is to put the
thermostat on the hot pipe going to the shower so that when the shower
is turned on it triggers the fan.

I'm planning to use 1.5mm twin and earth to make the connection
between the fan and the thermostat, which I think should be more than
adequate. But how should I connect the cable to those contacts on the
thermostat?

[By the way, the thermostat is from http://rswww.com part no 250-6106]

Why not use a humidistat, which would have the advantage of activating
the fan whatever the source of moisture - bath, shower or basin?

Those look like 0.25 in. blade terminals, so you need 0.25 in. insulated
crimp female receptacles, red or blue for 1.5mm^2. It's better to use
those on stranded flexible wire and connect to the twin & earth via a
suitable terminal block inside whatever housing you put the 'stat in.

Yep, I used basic Manrose humidistat in our bathroom. It works well on
the whole. Occasionally it comes on in response to general high humidity
outside, but normally works well.

clever idea, will give run on as well. Just check it goes up or down to
the required temp.
