A controlling and monitoring control application associated with one or more work operations of one or more utility devices is disclosed. The controller is programmed for controlling one or more external work operations associated with one or more utility devices. An I/O board is connected in communication with the primary controller having a module with a plurality of device-specific control applications associated with one or more device-specific work operations. The housing of the controller includes one or more cable access points for plugging a cable into the controller. The cable access points are sealed to prevent water from entering into the housing. A mounting bracket assembly provides flexibility for mounting the controller at various orientations and/or positions. The controller also includes a DC control circuit for controlling backlight luminance over the entire dimming ratio.

An out of product indicator is provided. The out of product indicator includes a power generator, a sensor and an alarm. The power generator is configured to generate power based on an interaction with at least one aspect of the device it is coupled thereto. The sensor is configured to determine when a product is low. The alarm is coupled to receive power generated by the power generator. Moreover the alarm is activated based on an output of the sensor.

A dispensercreates a use solution. The dispenserincludes a diluent inlet for receiving a source of diluent. A first aspiratoris in fluid communication with the diluent inlet. An operator valvecontrols flow of the diluent. A second aspiratorhas a diluent inlet, diluent outlet and a venturi port. A vacuum switchis operatively connected to the first venturi port and the flow of the diluent through the aspiratorcreates a vacuum that activates the vacuum switch. A control boardis activated by the vacuum switch and a dosing pumpis activated by the control device. The dosing pump dispenses a liquid product into the diluent stream, wherein a use solution is made.
