Braeburn 140404 Installation Manual page 8

3.3
Supply Air Sensor Wiring
Install the supply air sensor in the supply air plenum at least 2-3 feet after
the heat exchanger and coil. Make sure there are no zone dampers before the
supply air sensor. Connect the supply air sensor to the zone panel as shown.
3.4
Transformer Wiring
Install the transformer using the instructions provided by the manufacturer. Size the
transformer to the damper requirements. The zone panel has built-in, self-resetting
fuses. The maximum damper power per panel is 100 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
3.5
Conventional Equipment Wiring
NOTE: For a heat pump system, see Section 3.6.
Connect a conventional heating system to the zone panel as shown. For a single stage heating and cooling
system, the 2nd and 3rd stage connections are not used. For a system using a dual transformer, remove
jumper Rc to Rh (see Figure 3, page 4). Make sure the neutrals (common) are connected.
