General Note:

APPENDIX A. TERMINAL CORRESPONDENCE

The terminals of a VT8350 are identified differently and have a wider range of possible functions compared to those of any of the VT7000 Room  Controllers. Nonetheless, there is a direct correspondence of functions between the terminals of the VT7000 and the VT8350. Consult the table below to  verify the appropriate term when replacing a VT7000 Room Controller with a VT8350 Room Controller.

APPENDIX B. POWER OUTAGE CLOCK RESET

In the event of a power outage, VT8350 Room Controllers retain the correct time as long as the duration of the power outage is not prolonged. Depending on the duration of the power outage, the Room Controllers’ internal clock may need to be updated or reset completely. The following table indicates the expected clock performance after a power outage of a given duration.

APPENDIX C. DEPLOYMENT

The placement of the Room Controller must be given consideration. It is recommended to install the Room Controller as close to a door as possible  (without being blocked by the door), or in an area with high occupant movement.
Ideally, the Room Controller should be installed 5 feet (1.5 meters) above the floor surface to ensure maximum detection range is achieved. As well, Room  Controller placement should ensure the occupant crosses the lens beam in a perpendicular path within the prescribed detection zone.

C.1 EXAMPLE OF RECOMMENDED DEPLOYMENT
The below shows Room Controllers installed in ideal locations for two rooms.
The examination room shows one Room Controller installed adjacent to the door. In this area of the room, occupant traffic is high and ensures the occupant will almost always cross the PIR detection path laterally and within the detection range.
The waiting room shows one Room Controller installed beside a door in the middle of the room. As shown in the diagram below, occupant traffic is high in several areas of the room including the entrance, waiting room, access to the door, and activity around the reception desk.

Recommended Installation

C.2 EXAMPLE OF NON-RECOMMENDED DEPLOYMENT

The below shows four Room Controllers (two for each room) installed in non-ideal locations for the two rooms.
The examination room shows one Room Controller installed in a low traffic area near the door, and a second Room Controller installed on the wall directly opposite the door. For the Room Controller installed in the corner wall, the PIR could be blocked by the opened door, while occupant traffic could also be  minimal in this area of the room. For the second Room Controller installed opposite the door, the PIR detection could fall outside the specified detection zone, while at the same time most occupant movement would not be lateral to the PIR, thereby not respecting optimal crossing patterns for PIR detection.

The waiting room shows one Room Controller installed in the corner of the room, and a second Room Controller installed beside the reception area. For the Room Controller installed in the corner, the opening/closing of the door creates a high probability that the PIR would get blocked, and therefore,  occupancy going undetected. For the Room Controller installed beside the reception area, occupant traffic could fall outside the detection zone, and the receptionist would often be below the 5-foot recommended installation height for the Room Controller.

Non-Recommended Installation

C.3 ROOM CONTROLLER PIR SENSOR DETAILS

The internal Room Controller PIR sensor only detects lateral movement. It cannot detect movement when a person is moving toward it.
It will not detect someone seating on a chair and/or lying on the bed.

C.4 RECOMMENDATIONS FOR INSTALLATIONS

1. Install the Room Controller to cover the more lateral movement.
2. Install a door sensor, the internal Room Controller occupancy logic works better with a door sensor. Once a motion is detected after a door is opened,  the room stays in an occupied state until the door is opened again which puts the Room Controller in stand-by mode and if there is a motion then it goes back in occupied mode. It is also recommended to disable the unoccupied mode, set the “unoccupied time” to 0, so there are only 2 modes in the  Room Controller: stand-by and occupied for a standalone solution. Please refer to the two(2) diagrams below for the Room Controller internal occupancy states transition.
   
3. Install additional motion sensors in the bathroom.
4. Install additional motion sensors for better motion detection in the entire room.

C.5 ENERGY SAVINGS
PIR can maximize your energy saving from 10-30% by adjusting temperature set points in unoccupied zones during scheduled periods.
