Light Dimming Relay
5.6.1 Operation
The controller signals the light dimming relay to turn "fully on", "partially dimmed", or "completely off" by sending
a speci
fi
c number of pulses in a set period of time to the light dimming relay. The circuitry of the light dimming relay,
which requires 120 VAC to operate, interprets the number and timing of pulses to determine whether the light should
be on, off, or dimmed.
The circuitry of the light dimming relay is driven by the 120 VAC power from the circuit breaker for the light. Un-
like a standard relay, which receives a constant 24 VDC to its coil to hold the relay contacts closed (and which opens
when that voltage is removed), the light dimming relay receives only signal pulses on the relay coil wires, and it is the
circuitry on the relay that actually turns the light on and off and dims it. Therefore, if the light is fully on or dimmed,
unplugging the relay coil wires to the light dimming relay will not turn the light off. The light will remain on as long
as 120 VAC is supplied to the relay.
Note: In addition to needing a light dimming relay installed, the auxiliary to operate the light dimming circuit must be assigned at
the indoor controller.
