Mounting
Connect as shown 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.)
NOT
E: The “C” terminal on these relays does
NOT denote AC Common/Neutral! “C”
is connected to the PHASE side of the 24
VAC (and the phase side is where the three
contactors are connected in “common”).
“9” is the neutral side.
NOTE: Triac s
tages 1 through 3 are for 24 VAC
loads only.
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 differential 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.
