Use #18 gauge 2-conductor twisted pair cable between the Lightstat TME and
the damper or equipment to be shut down.
A1-A2 cable does not have polarity, either wire may be connected to either
terminal. Cables do not have to be shielded.
At the Lightstat TME end connect the cable to the two terminals marked A1 and
A2. At the other end, connect it to the damper or equipment.
The A1 and A2 terminals are an isolated set of dry contacts rated at 2 amps (24-
30VAC).
They are typically OPEN during the occupied period and CLOSED during
Setback. They will OPEN during the pre-condition period.
