SOLUTIONS:	DETAILS:	CLICK FOR INFO:
Air Conditioning System	Capable of measuring air temperature and humidity as well as incorporating an electric motor and a programmable microcontroller to enable accurate temperature control. With keypad to input desired temperature and LCD to show set or actual temperature and clock timer for time and 7 day programming. NEC's range of 8 / 32 bit K1 micros (78K0/V850) can provide solutions optimised in cost/performance
Outdoor Temperature Sensor	Capable of measuring temperature or humidity these outdoor sensors enable more sophisticated control by the central heating unit. Devices may be mains or battery operated and advanced systems may include the option of synchronising with a remote real time clock. NEC's 8 bit micro range (78K/78K0S) is ideally suited to these applications.
Programmable Radiator Thermostat	These devices incorporate an electric motor and a programmable microcontroller to enable accurate temperature control of the radiator with keypad to input desired temperature and LCD to show set or actual temperature. In battery driven situations low power indication is provided. Optionally these devices may have wireless communication with the central control unit. NEC's 8 bit micro range (78K/78K0s) with "motor control" features is ideally suited to these applications.
Hot Water Dispenser	Independent from the main system - a hot water dispenser provides instantaneous temperature regulated water. Electronics provide monitoring and control of water temperature, flow rate and heating system, while displaying the settings on an LCD panel. Advanced systems may include the option of synchronising with a remote control unit. NEC’s 8 bit micro range (78K/78K0s) is ideally suited to these applications.
Programmable Room Sensor	The programmable room sensor controls room temperature for all the heating systems. A display maybe mounted in the control panel to provide a user interface for control of the central heating. Some room sensors may include remote access via an Infra-Red (IR) control unit.
Solar Control Unit	Solar heating systems can provide an additional source of water heating to supplement the Central Heating system. The Solar Control unit's function is to optimise the transfer of solar heated hot water, provide monitoring of the temperature of the water system and controls the associated valves and pumps. NEC's range of 8 and 32 bit micros (78K0/V850) can provide solutions optimised in cost/performance.
Central Heating Unit	The key control component in a heating system enabling programmable control over the operation of the entire system. The control unit receives data from the array of sensors from the air temperature / humidity to the water temperature and communicating and controlling all components of the system, such as the Burner Control Unit. Dependent on the sophistication of the system the CHU may also provide direct control of system pumps. Whatever the level of sophistication required, NEC's range of 8 and 32 bit micros (78K0/V850) can provide solutions optimised in cost/performance.
Burner Control Unit	Control over the proper ignition and combustion of the burner is accomplished with the Burner Control unit, which provides for example monitoring of the gas supply, control of the gas valve and spark control. NEC’s 8 bit micro range (78K /78K0s) is ideally suited to this application.
