Transformer Wiring
Install the transformer using the instructions provided
by the manufacturer. Size the transformer to the damper
requirements. The zone panel has a built-in, self-resetting
fuse. The maximum damper power per panel is 35 VA at
24 VAC.
Connect the transformer to the zone panel as shown.
Note:
Additional dampers or dampers with a higher current draw will require the use of a separate
slave relay.
