Mounting
The REE-5001 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.
Connect as shown below and/or in the sample
illustration on the next page. Supply the relay with
24 VAC, +20%/ –15%. (Use wire size of 14 to 22 AWG,
stranded.)
NOTE: Triacoutputsarefor24VACloadsonly.
Check the graph for thermostat signal setpoints and
corresponding stages. Stage 1 turns on at 3.5 VDC,
Stage 2 at 6.5 VDC, and Stage 3 turns on at 9.5 VDC.
NOTE: There is a 2 VDC switching dierential on
each stage.

Maintenance
No routine maintenance is required, however protec-
tion from extremes of humidity and dirt is recom-
mended. Careful installation will also ensure long
term reliability and performance.

Troubleshooting
• Check the wiring.
• Check the voltage from the thermostat/control-
ler (measured from Terminal T to Terminal –/
Neutral). (See the voltage charts aboveandon
thepreviouspage.)
• Check the voltage across the triac and load. (See
the chart below.)
