OSmart™ equipped model)
The CB100S is equipped with a circuit board that controls how
the fan and water valve are powered. Figure 9 shows the
main parts of the board. The wiring diagram is shown in figure
10. Refer to the wiring notes shown after Figure 10 for board
wiring/control configurations that explain how to set the board
based upon the type of system it is being installed on. These
recommendations will provide the best performance and water
savings.

Wiring the low voltage portion of the unit:
The source of 24 VAC (low voltage) comes from the HVAC
system terminals. The typical terminal designators are used,
such as R, C, G, W, etc. The following list identifies the low
voltage terminals and their respective connection.
•
R = 24 VAC from the HVAC system
•
C= 24 VAC common from the HVAC system
•
Hr = 24 VAC output for powering the electronic humidistat
(if equipped)
•
Hc = 24 VAC common for the electronic humidistat (if
equipped)
•
H = Humidistat input (must be 24 VAC)
•
W/G = Input from HVAC system. This is used when the
humidifier is used with warm air furnaces.
•
AP1/AP2 = Air proving switch is connected here. Do not
apply voltage.
•
Go = 24 VAC output may be used to energize a relay or
connected back to the thermostat “G” terminal to turn on
the HVAC fan. Thermostat functionality may vary and
affect the operation of this output.
DIP Switches/Settings:
•
DIP #1 = Bypass or Motorized (Factory Set)
•
DIP #2 = High Capacity/Low Capacity - This is factory
set to High Capacity. If you determine that the humidfiier
is too large for the load, you may change the DIP switch
position to ON. It is not necessary in most cases.
•
DIP #3 = Temperature Check - If you are installing this
humidifier on a system that will have duct temperatures
regularly below 100°F, set this DIP switch to the OFF
position. Typical furnace bonnet temperature is nominally
120°F.
