Parking lot controllers are electronic devices that control the electricity going to an outdoor plug, allowing building and property managers to effectively manage electricity use in their parking lots.
Parking lot controllers reduce electricity costs by up to 50 per cent, yet ensure trouble-free starts for tenants, staff and guests. They save energy by automatically adjusting the length of time that electricity is provided to the car plugs, depending on outside temperatures.
Above –5 C, outlets typically receive no electricity. As the temperature drops, electricity is progressively delivered for longer periods of time. Once the temperature drops (usually to between –20 C to –30 C), the power stays on all the time. Plug power is controlled from a central controller and contactors connected to the central breaker panel or by circuitry built inside the receptacle.
Tenants, staff, and guests appreciate parking lot controllers and are reassured to know that their vehicles are getting the right amount of energy they need to start under all weather conditions. Some controllers also automatically limit the maximum current drawn, which prevents circuit breakers from tripping and cutting off all power to the block heater in the event of an over current.
Please note that our incentive program for parking lot controllers ended March 31, 2010.
