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.

Sequence of Operation and Wiring

Occupied Mode

Setpoints revert to those dened by occupied cooling and heating.

UI 24 - Airow

Options

• Wireless adapter modules for BACnet models are available. (see Appendix B for network wiring).

• 3 universal inputs can be used and congured for advanced

Stand-by Mode (only available when PIR motion detector

functionality as required by the application.

sensor is used)

Setpoints revert to those dened by stand-by cooling and heating.

Unoccupied Mode

Setpoints revert to those dened by unoccupied heating and cooling.

Occupied Override Mode

System reverts to occupied mode for duration determined by “ToccTime” parameter.

In all Occupancy Modes

If room relative humidity is higher than the user-dened Dehumidication setpoint, both Dehumidication, UO12 and Fan BO4, outputs are

energized to reach the setpoint and the Room Controller Cooling and Heating outputs will not trigger. If room relative humidity is higher than the

dehumidication set point + hysteresis, the Room Controller will energize dehumidication terminal UO12, BO8 and the cooling terminal BO3. During the dehumidication cycle, the Room Controller modulates heating output UO11 to maintain the room temperature set point.

*A multi-pole relay may be required to activate Cooling and Heating stage(s).
