How to Use This Manual Supplement
This supplement replaces pages 13-36, Menu and Menu Items and pages 50-51, Appendix B Wiring
Information of the Model 8682 S
(P/N 1980288).
This supplement describes the menus and menu items used to configure and program the controller
and how to wire each component.
Sequence of Operation
The Model 8682-KF1 uses the standard Model 8682 pressure and tracking control algorithm. The
Model 8682-KF1 also features temperature control. The temperature control scheme provides
modulation of supply volume for cooling and modulation of a reheat valve for heating.
The Model 8682-KF1 laboratory control system uses a through-the-wall room pressure sensor to
measure pressure differential (direct pressure measurement) between the laboratory and corridor
(reference space), and receives temperature information from the thermostat (0-10 VDC, 50-85°F).
The pressure sensor is located on the corridor (reference space) side of the wall. The Model
8682-KF1 laboratory controller continuously monitors the thermostat information. The Model
8682-KF1 control algorithm modulates supply and general exhaust air flows to provide adequate
fume hood replacement air while maintaining room pressure differential and temperature control.
