Proportional to Tri-State Control, Relay Module
Installation Guide
REE-5525
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
Connect as shown. Supply the relay with 24 VAC
(+20%/–15%, Class 2 only). (Use wire size of 14 to 22
AWG, stranded.)
NOTE: The 24 VAC sources can be the same or
separate, with no regard to phasing.
NOTE: Triac outputs are for 24 VAC loads only.
Outputs are optically isolated from the
control 24 VAC power.

SIGNAL
The stage sequence operates in this manner:
• Stage 1 turns on at or below 1.5 VDC* and o at
or above 3.5 VDC. (It is on at 0 VDC.)
• Stage 2 turns on at or above 9.5 VDC* and turns
o at or below 7.5 VDC. (It is on at 10 VDC.)
• Both outputs are o between 3.5 and 7.5 VDC.
*NOTE: In the dark grey regions of the chart, the
stage is denitely on for the given voltage.
In the light grey regions, however, on or
o depends on the previous state. For
example, at 2 VDC, Stage 1 will be on if the
previous voltage was 0 VDC (Stage 1 on)
but o if the previous voltage was 5 VDC
(Stage 1 o).

Troubleshooting
• Check the wiring.
• Check the voltage from the controller, measured
from Terminal – (under 24 VAC) to Terminal
0–10 IN. (See the Sequence chart on the previous
page.)
• Check the voltage across the triac and load. (See
the chart below.)

Maintenance
No routine maintenance is required, however protection from extremes of humidity and dirt is recommended. Careful installation will also ensure long
term reliability and performance.
