OVERVIEW
SE8600
The SE8600 Rooftop and Indoor Air Quality Controller is a new, cost-effective solution for upgrading rooftop unit thermostats. This solution allows existing wiring between the rooftop unit and the temperature controller to be re-used, reducing overall costs and installation time. The SE8600 can also add new features like CO a rooftop unit.
The SE8600 Rooftop and Indoor Air Quality Controller can be configured to handle a broad variety of applications covering all the standard implementations necessary for rooftop HVAC systems.
In addition to controlling heating, cooling and air quality, depending on the model and accessories, the SE8600 can handle wireless networking and switches, Passive Infrared (PIR) occupancy detection using either onboard or remote sensors, and can have custom programs implemented to fulfill specific user requirements.
The applications described here cover all these features, and in combination with the SE8600’s advanced scheduling and occupancy controls can provide the functionality for any required rooftop HVAC implementation.

FRESH AIR DAMPER CONTROL SEQUENCES
The fresh air damper can be controlled through more than one sequence to achieve different control strategies such as free cooling (economizer mode), minimum fresh air control and CO2 level control. Here are the control sequences available:
Note: For the sequences mentioned below, the following conditions must be met in order for the sequences to be performed as stated:
• Max Pos parameter value must be greater than Min Pos Parameter value.
• Mac CO2 parameter value must be greater than Min CO2 Parameter value.
• Max FA parameter value must be greater than Min FA Parameter value.

Economizer Control Mode Only
If the fresh air damper is to be used only for free cooling purposes (economizer mode, without fresh air measurement station or CO2 control), only the Min Pos parameter and the free cooling sequence will be active.
• The FA Range parameter should be set to 0 CFM. (Default Value = 0 CFM)
• Set the Chngstpt parameter to desired value which free cooling is enabled. (Default Value = 55°F)
If the outside air temperature is greater than the changeover setpoint, then normal mechanical cooling will be used. If the outside air temperature is less than or equal to the changeover setpoint, then free cooling will be enabled and mechanical cooling stages will be locked out.

Economizer Control Mode and Fresh Air Measurement Station
If the fresh air damper is to be used for both free cooling and minimum fresh air volume control (economizer mode and fresh air measurement station, but without CO2 level control), only the Min FA parameter and the free cooling sequence will be active.
• The FA Range parameter should be set to a value higher than 0 CFM (0 CFM disables the fresh air control).
• Min FA (minimum fresh air) parameter should be set to the desired level.
The FA Range parameter value should be set to the maximum capacity of the fresh air measurement station. Therefore the relationship between air volumes and input signals can be established. For example, if the fresh air station capacity is 10000 CFM, set FA Range to 10000.
This will set the relationship of 0 VDC = 0 CFM and 10VDC = 10000 CFM.

• Set AI1 parameter to CO2 (0 VDC = 0ppm ; 10VDC = 2000ppm)
• Min Pos, Max Pos, Min CO2 and Max CO2 parameters should be set according to the required setting.
The highest value between free cooling demand output and interpolation output for the fresh air setpoint will be the output to the fresh air damper.

• Use an air ow transmitter to read fresh air level with AI2 input (0-5 VDC input)
• Min FA, Max FA, Min CO2 and Max CO2 parameters should be set according to the required setting.

Deployment
It is recommended to install the Room Controller as close to a door as possible (but not so as to be 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.
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. Moreover, for each case aforementioned, occupant movement almost always moves lateral to the PIR, which ensures detection by the PIR, as well as respecting the PIR detection range of 20 feet (6 meters) at 140°, and 16 feet (5 meters) between 15° to 30° laterally.

Schneider Electric | AG-SE8600-RTUIAQ-A4.EN.10.2016.v4 November 2016
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 near the door, the PIR could be blocked by the opened door, thereby restricting PIR detection. 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 may not respect lateral crossing patterns for PIR detection.
The waiting room shows one Room Controller installed near the entrance, and a second Room Controller installed beside the reception area. For the Room Controller installed at the entrance, the opening/closing of the door creates high probability 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, while the receptionist would often be below the 5 foot recommended installa­tion height for the Room Controller.

• Wiring should be daisy chained
• Respect polarity
• If using 2 conductors shielded wires, connect the shield of each feed together on the back of the controller. ONLY ground the shield at one location. DO NOT connect the shield to the ref terminal.

APPENDIX D - WIRELESS SENSORS
Wireless ZigBee Pro Motion Sensors
Rooftop Unit and Indoor Air Quality Controllers with ZigBee Pro wireless sensors can be used in stand-alone mode, or with integration to a central management system, to allow for advanced functions such as central reservation and occupancy functions.
Up to ten different ZigBee motion sensors and switches (SED-WMS, SED-CMS, or SED-WDS) can be used with a SE8600 Room Controller.
No tools are required for commissioning or servicing the ZigBee devices. A simple interface on the devices with an on-board LED and hidden switch provides all required functions for local interaction. The SE8600 user interface has screens used to pair and
congure ZigBee devices (SED-WMS, SED-CMS, or SED-WDS only). Local information for battery life and connectivity (heartbeat)
are also displayed through the ZigBee Pro wireless network.

APPENDIX E: TERMINAL CORRESPONDENCE
The terminals of an SE8600 are identied differently and have a wider range of possible functions compared to those of any of
the SE7000 series Room Controllers. Nonetheless, there is a direct correspondence of functions between the terminals of the SE7000 series and the SE8600 series. Consult the table below to verify the appropriate terminal when replacing a SE7000 Room Controller with a SE8600 Room Controller.
