Mounting
The module may be mounted directly to a control
box surface or in a 2 x 4" electrical handy box. Add a
blank cover to conceal the module if desired.
Connections and Wiring
1. Connect a controller input to one of the three
THE-1102/REE-2002 (0–5 VDC, 0–10 VDC, 4–20
mA) outputs as shown in the sample illustration
below.
2. Connect the B, F, C, and D terminals to the
corresponding terminals on the THE-1102.
3. Supply the REE-2002 with 24 VAC (+20%/–15%)
from a Class 2 transformer (only).

term reliability and performance.
Troubleshooting
• Check the wiring.
• Check the voltages.
More Information
NOTE: The REE-2002 may also be used to convert
0–5 VDC signals from building automation
systems to 0–10 VDC or 4–20 mA signals.
See the graph for output options over a 0–5
VDC input range.
For more information about
using the THE-1102 with the
REE-2002, see the THE-1102
Installation Guide.
