Anguloa Clowesii low temperature tolerance

[Fredmax]

Hi, I have a large healthy Anguloa Clowesii which I purchased on reference of Andy's Orchids site mentioning it can support 40f.

Now that I have it I've immediately moved it back inside with low humidity but lows average of 55f to protect it from cold as am scared my assumption may be wrong.

For anyone who successfully cultivates it are you aware of if it can tolerate 40-45f, my winter is currently around 45f and would love to put it back in the glasshouse with the Lycomormium which seems to be doing ok, but lack the experience without finding out the hard way.
