Manual position (amber) This indicator is on whenever the HC-150 is operating in
the manual mode. The unit runs continuously until it is
switched off.
Running light (green) This indicator is on whenever the unit is running (the Auto/
Off/Manual switch is in the Manual position, or the switch is in
the Auto position and the humidistat contacts are closed).
Fault light (red) This indicator is normally off. This light turns on when the
unit overheats. See the section on “Troubleshooting.”
Time meter This indicator shows how many hours the unit has operated.
The control system uses a number of sensors and controllers to supervise the activity of
the HC-150. On the model HC-150I only, a Solid State Power Controller (SSP1) turns
the heating elements on and off. This controller responds to a signal from a temperature
sensor (TSE1) which is located in the reactivation air stream after the wheel. (This design
allows reduced energy consumption at low load levels.)
