How does the lockout card actually work?

General FAQs

How does the lockout card actually work? I saw your bulletin that shows how to disable by removing the PT1, but I don't want to do that. Does the card just block the connection between the PT1 and the item marked LED? What is the actual connection made with...light?

The connection is made with light. The receptor is blocked by the key card which "unlocks" the temperature control.
