PIR detecting energy saver hotel Magnetic window contact energy saver
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.

>>General.
>> 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 detect if there is movement within 3s~T4 in the room
during this time, if any PIR presence detectors indicates movement, the system will assume that there is presence in the room, then it will operate as an "Occupied" mode maintaining activate S1, S2 and S3 circuit. If no movement,the system initiates the programmed delay time and disconnect the various outputs.
>>Window Contact Algorithm
The 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.
