Check the graph for thermostat signal setpoints and

corresponding stages. Stage 1 turns on at 2 VDC,

Stage 2 at 4 VDC, and Stage 3 at 6 VDC. There is a

0.33 VDC switching dierential on each stage.

The REE-4001 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.

GND (–) OUT (+) 24 VAC Stages (Alternate Direct Control from an Analog or DDC Controller) NOTE: The “C” terminal does NOT denote Common/Neutral. “C” is the phase side of the 24 VAC (and is also the side the contactors have in “common”). “9” is the neutral side. Triac stages 1 through 3 are for 24 VAC loads only.
