Abstract
An anti-condensing system includes a control panel configured to electrically couple between a power source and a temperature regulating display unit. The control panel includes a housing defining an interior cavity, a door selectively repositionable to facilitate accessing the interior cavity of the housing, and a circuitry assembly disposed within the interior cavity. The circuitry assembly includes a relay configured to couple to a heating element of the temperature regulating display unit, an overcurrent protection breaker coupled to the relay and directly integrated into the control panel such that the overcurrent protection device can be locked out at the control panel, and a control circuit coupled to the relay. The control circuit is configured to actively control the relay to prevent condensation from forming on the temperature regulating display unit.
