TERMINAL CONTROL DIAGRAMS
Occupancy control is achieved by connection to the terminal
interface shown below. These terminals require a dry contact which
could be provided by a number of types of controls such as a timer,
light sensor, occupancy sensor, building management system,
or other. The unit will not operate unless these contacts are
closed!!
The illustration below shows a factory installed jumper and
programmable timer option (supplied by others).
Remote fan control can be achieved by connecting dry
contact controls to the terminal interface at terminals labeled:
LOW - COM - HIGH.
These controls could be the following: SPDT switch, dehumidistat,
CO

sensor, light sensor, timer, building management system, etc.,
supplied by others.
The illustration below represents a switch connected to the unit.
