Hi.
This fan motor at the bottom works on 240VAC into its purple and black wires. Its red wire is for slow speed, not used, and shown connected to a 'parking' terminal just to prevent from being loose around. Ignore its red wire as there is no connection.
There is a wire between M1 and a normally closed contact of a relay at bottom. What is it for, how does it work ?
Or, if you prefer the original, is on page 6 ----> http://www.alpinehomeair.com/related/ARPF Spec1.PDF
with the second 2-heater option installed.
