The invention provides apparatus for controlling a search lamp using a wireless transmitter and receiver. The transmitter responds to user inputs by providing a wireless digitally encoded modulation signal containing information indicating at least one operation in a set of operations the search lamp is able to perform. The receiver responds to the wireless digitally encoded modulation signal by providing a control signal for controlling the functionality of the search lamp. The functionality may include, for example, moving the search lamp left/right and/or up/down, a sweep on/off @ +/&#x2212;45 degrees; X/Y/Z movement (Z when motors run simultaneously); Diagonal sweep (motors run simultaneously); Fast/Slow sweep (50%/100%). The transmitter and receiver are programmable to communicate on a unique 16 bit digital code setting that provides about 65K different code settings, which may also include a random code setting.

A hose separation transmitter system includes a shock sensor and a transmitter that are secured to the delivery hose. If the hose becomes disconnected, the shock sensor will generate a shock signal when the hose falls to the ground and the transmitter will respond to the shock signal by generating an encoded RF signal. A receiver at the vehicle receives the RF signal from the transmitter, determines that a hose disconnect has occurred, and automatically disables a fluid pump or closes a valve to stop the flow of fluid. The shock sensor preferably uses a strip of piezoelectric material. Related methods are also disclosed. For quick connect and disconnect, the shock sensor and transmitter are preferably secured to the hose by a hook and loop fabric material. The transmitter is immune to normal ambient vibration levels. Related methods are also disclosed.

A safety circuit for use with a spa system includes a pressure sensor which generates a signal representative of the pressure in the system. The safety circuit provides a constant current to the pressure sensor. A microcontroller is coupled to receive the signal from the sensor and is configured to store a first pressure level. The microprocessor compares the first pressure level with the subsequently measured pressure level and generates a control signal if the comparison indicates a change in pressure which exceeds a predetermined amount. The control signal is sent to a spa control circuit. An electronically controlled switch is coupled to receive the control signal from the microcontroller and turn electrical power to the pump off in response thereto.

A heater assembly for use with spas, hot tubs and the like, includes a control circuit which controls the application of electrical power to the heater. A control circuit controls application of power to the heater in response to a thermostat setting, the flow of water in the spa system and in response to a high limit temperature. When the high limit temperature is exceeded, electrical power to the heater is removed. Electrical power to the heater cannot be restored until power to the entire system is turned off and then back on. The control circuit is mounted on the heater and includes spring-loaded standoffs which maintain the temperature sensors in good thermal contact with the body of the heater.
