Operation:
The Controller signals the Light dimming Relay to turn ‘fully on”, “partially dimmed”, or “completely off” by sending a
specific 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) then 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. Unlike
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 on, off, and dims the light. Therefore, if the light is full on or dimmed, unplugging the relay coil wires
to the Light Dimming Relay will not turn off the light. The light will remain on as long as 120 VAC is supplied to the relay.
The Light Dimmer will operate slightly differently when activated from the Controller, Power Center or Spa Side
Switch.
From the Controller - When the auxiliary, which has been assigned to light dimming is pressed or programmed on,
the light will turn on to the brightness last set by pressing Back or Forward Buttons. Once on, the brightness may
be changed by pressing the Back or Forward Buttons. To turn it off, press the auxilliary button again.
From the Power Center override switch - Pressing the appropriate auxilliary button will turn the light on to the
brightness last set at the Controller or Spa Side Switch.
From the Spa Side Switch - If a button on the Spa Side Switch has been programmed to control a Light Dimmer
auxilliary, the first press of this button will turn the light on to full brightness, each additional press will dim the light
in 25% increments until the light is off.
Note: Besides needing a Light Dimming Relay installed, the auxilliary to operate the light dimming circuit must be assigned
at the Controller using the Menu button and moving to the SETUP Menu.
