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]
