Damper Wiring
3.1
Always turn off power to the heating/air conditioning system prior to installing or adjusting the zone panel. Wire 
the entire panel before applying transformer power.
Use the following general wiring instructions for all systems. Specific wiring will vary depending on the equipment 
and type of system (conventional or heat pump).
Install the system dampers using the instructions provided by the manufacturer. Connect the dampers to the zone 
panel as shown for either a 2-wire or 3-wire damper. The sum of all dampers powered by the zone panel should 
not exceed 100 VA at 24 VAC. Use a slave relay if additional damper power is required.
ALWAYS PROVIDE DISCONNECT AND OVERLOAD PROTECTION AS REQUIRED
