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.
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.

The stage sequence operates in this manner:
• Stage 1 turns on at or below 1.5 VDC* and off at
or above 3.5 VDC. (It is on at 0 VDC.)
• Stage 2 turns on at or above 9.5 VDC* and turns
off at or below 7.5 VDC. (It is on at 10 VDC.)
• Both outputs are off between 3.5 and 7.5 VDC.

SEQUENCE
*NOTE: In the dark grey regions of the chart, the
stage is definitely on for the given voltage.
In the light grey regions, however, on or
off 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 off if the previous voltage was 5 VDC
(Stage 1 off).
