WIRING
WARNING
Serious Personal Injury or Equipment Hazard.
Moving parts can cause electrical shock and injury.
• Disconnect power supply before installation or servicing.
• This device contains a moving fan blade; do not operate the
humidifier without the cover securely attached.
All wiring must comply with applicable local codes, ordinances and
regulations.
For H8908B Humidistat Wiring Connections:
IMPORTANT
• Select models of fan centers include humidifer taps so the
current sensing relay or sail switch is not needed.
• If not using a current sensing relay or sail switch, the 120V
humidifier plug must be energized during blower motor cycles
for proper operation.
1. Wire the current sensing relay or sail switch.
2. Connect only the two yellow wires to the humidistat (red wire
connections are not used for mechanical humidistats). See the
typical wiring diagrams in Fig. 5 through 7.
For additional mounting and wiring information, refer to the humidistat
installation instructions.
