General
Hotel in Room Technology Energy Saver Switch with Key Systems(HTW-61-ES6201) is designed to control electrical consumption by detecting occupied/unoccupied presence, in order to connect/disconnect the air conditioning equipment and lighting automatically when the customer accesses or leaves the room.

PIR presence detector operating algorithm
HTW-61-ES6201 has 1 input (E1) for a magnetic room contact placed on the doorframes of the room;
1 input (E2) for a magnetic window contact placed on the window frames. 
3 inputs(E3,E4,E5) for PIR presence detectors.
When the door of the room is open, the energy saving system is activated instantly, and feed the following three outputs:

S1-Air-conditioning output with anti-humidity mode;
S2-Air-conditioning/Lighting output with delay time;
S3-Lighting output with delay time;
Once the door is closed, the system will try to determine if there is movement within 3s~T4 in the room


Magnetic window contact operating algorithm
If a magnetic window contact switch is connected to the terminals 12-13, when the contact is open, the output S1 will disconnect after 1min, until closing window contact again.
