6000 SERIES HUB WIRING

WARNING
120 volts may cause serious injury from electrical shock. Sudden
operation may cause serious injury from moving parts. Leave
power disconnected until installation is complete.
Follow these steps for all system connections. Wiring will vary
depending on equipment. Wiring of the system must comply with
applicable codes, ordinances and regulations.
• Use only 18 or 20 gauge solid (non-stranded) wire.
• Strip off 7/16" of insulation from the wire.
• Push wire into the terminal of the 6000 Series Hub.
• To release the wire, press down on the top of the terminal and pull
the wire out.
• The 6000 Series Hub supports multiple options to route and anchor
wires to the housing. See FIGURE 5.

TRANSFORMER

Note: The HVAC equipment transformer cannot be used for power. A
separate transformer should be used to power the system.
1. Wire 24VAC from transformer to the POWER, R and C terminals (see
FIGURE 6).
2. Sizing of transformer to accommodate the number of dampers:
a. Select your damper type.
OPTION 1: Normally Open/Power Close Dampers (2-Wire)
i. Add up all the zone dampers that are in the system.
ii. Subtract the number of dampers in the zone with the least number of dampers. This is the greatest number of dampers that could be
energized at one time.
iii. Multiply this number by 10 to determine the damper VA requirement. Add an additional 10VA for the 6000 Series System.
Example: If you have a 3-zone system, and there are two dampers per zone, then the total number of dampers that could be energized at
one time is,
6 dampers – 2 dampers = 4 dampers
4 dampers x 10VA per damper + 10VA for 6000 Series System = 50VA required
OPTION 2: Power Open/Power Close Dampers (3-Wire)
i. Add up all the zone dampers that are in the system.
ii. Multiply this number by 2.5 to determine the transformer size. Add an additional 10VA for the 6000 Series System.
Example: If you have a 3-zone system, and there are two dampers per zone, then the total number of dampers that could be energized at
one time is,
6 dampers x 2.5VA per damper + 10VA for 6000 Series System = 25VA required
b. Select a transformer that meets or exceeds the value calculated.
