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 zone is 75 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.
ALWAYS PROVIDE DISCONNECT AND OVERLOAD PROTECTION AS REQUIRED
