Connect Multiple Distribution Panels - Aprilaire 8800 System Installation Manual

CONNECT MULTIPLE DISTRIBUTION PANELS

1. MAKE SURE THAT ALL SWITCHES ON THE DISTRIBUTION PANELS ARE OFF!
2. If more than one Distribution Panel is used in the thermostat network, the communication lines must be daisy-chained together.
• Use the wire colors shown in FIGURE 7 to help ensure proper, consistent connections.
3. Power from the HVAC equipment or plug-in transformer can be used to power multiple distribution panels, but if you are powering the panel
from a thermostat, use one thermostat per panel.
