Combination of window contact and key card contact logic • The window contact has priority over the delay timer and the Setback functionality of the key card contact: When the window contact is opened while the key card contact is open, the delay timer will immediately expire if it is still running, and Setback will not work anymore. The reset timer will immediately start counting or will not reset when it was already running. • The reset timer functionality of the key card contact has priority over the window contact when returning to the previous state: When the key card contact is opened while the window contact is open, the delay timer will start running.
When the delay timer expires the reset timer will start running. When the reset timer expires, the previous state is updated to the “Default Reset Setting” state. Example 1 1 : You remove the key card. Result: The indoor unit continues operating normally until the delay timer expires. 2 : You open the window before the delay timer expires. Result: The indoor unit stops immediately. It is not possible to turn the unit on or off, the Setback functionality does not work, the delay timer stops counting, and the reset timer starts counting. 3 : You insert the key card again. Result: An update of the previous state occurs.
The unit is forced off and the Setback functionality is still disabled (see “Window contact logic” on page 38). IF the reset timer HAS NOT expired before inserting the key card, the previous state is the same as the original state because there was only a change to the original state. IF the reset timer HAS expired before inserting the key card, the previous state is the “Default Reset Setting” state. 4 : You close the window. Result: The unit reverts to the previous state. The previous state depends on the expiration of the reset timer. 40
