Printed Circuit Board in the humidifier. It incorporates all the control functions.
(See section 10–Description of the Control PC board)
Wall humidity controller with set point adjustment knob and an alarm indicator (red)
(see section 14-Types of alarm).
Locate this item on an inside wall which will serve as a reference for the humidity
level in the residence or the controlled space.
Remote set point controller with set point adjustment knob and an alarm indicator
(red) (see section 14-Types of alarm). This item requires the use of the duct humidity
controller (HD) HRD100.
Duct humidity controller with set point adjustment knob and an alarm indicator (red)
(see section 14-Types of alarm). If this item is used with the (SR) SSR100, the
switch on the (HD) HRD100 must be positioned at ROOM SET POINT, otherwise set
the switch to DUCT SET POINT (default).
Install this item in the return duct of the ventilation system.
Airflow proving switch with status indicator (green). The indicator is on when
airflow is detected. Install this item on the supply duct up-stream from the steam
dispersion tube. Insert one extremity of the transparent tube into the duct and the
other end into the tube connection P1 of the airflow proving switch.
Airflow proving switch and a high limit humidistat with status indicator (green).
The indicator is on when airflow is detected. This item replaces the (APS) AFPS100.
Install the (APS/HL) HRDFS100 in the supply duct 5 feet (1.5m) down-stream of the
steam dispersion tube.
Window temperature sensor.
