Determining Occupancy

Honeywell Hospitality (formerly Inncom) motion based occupancy logic for guestrooms has been in use for more than 20 years. Occupancy logic control in the guestroom saves more energy, contributes to the hotel’s CSR programs and provides your staff with valuable information on room occupancy.

The Honeywell system uses two inputs. A signal from an entry door switch acts as the system trigger and a passive infrared (PIR) motion sensor confirms actual presence of guests or staff. Combined with the software logic of the thermostat, the system can accurately determine occupancy versus vacancy of the room.

Simply put –> door open/close + motion sensed = occupied room.
Alternately, door open/close + no motion sensed = vacant room.

A third key factor is the time delay. Each time the entry door switch indicates the door has opened and closed, an evaluation period begins. The room is set to, or kept in, in an occupied mode while the Honeywell smart thermostat “evaluates” the status of the room.

During this time delay period, if motion is seen by the Honywell thermostat, from a guest or staff, the temporary status is confirmed as occupied and the AC (and optionally lighting) remain on. In the occupied mode, the Honeywell smart thermostat keeps the occupied state whether the guest is sleeping or in the bathroom. No change will occur unless and until both the door opens and closes, and no motion is sensed by the PIR during the time delay period.

If the time delay evaluation period ends with no motion seen by the Honeywell thermostat, then and only then will the room go to “unoccupied” mode enabling the pre-set energy savings functions.

Honeywell’s PIR occupancy control logic is 99% accurate and cannot be overridden by guests or staff, like key tag systems can. It has been installed in more than 2 million guestrooms globally and is used by many of the most well known hotel companies in the world.
