The PaceController establishes optimal run times for compressors and burner units, "pacing" the equipment's consumption of electricity, natural gas, fuel oil or propane. The PaceController…

	Is installed within the existing control lines of heating, ventilating, air-conditioning and refrigeration equipment
	Operates the compressor or burner unit at an optimized interval, always within manufacturer guidelines
	Maintains full end-use performance of the paced equipment
	Can allow local condition changes (such as outside temperature) to temporarily set new intervals automatically

Cooling and Refrigeration Systems
Cooling efficiency in an air-conditioning or refrigeration unit doesn't depend on the amount of time the compressor is running. Efficiency depends on the density of refrigerant that is being moved per unit of time. In most cooling systems, the compressor keeps running until the thermostat indicates that the set point has been reached.

That's where the PaceController comes in. The PaceController carves out the most efficient slice of compressor run time. Even when the compressor is not running, cooling continues as the refrigerant continues to change state, and the circulating fans distribute the cooled air. Reduced compressor running time means:

	Less icing on evaporation coils, providing more efficient heat transfer
	Less energy used in a defrost cycle
	Lower average compressor stator winding temperatures, which can lead to increased compressor life

Heating Systems
In many heating systems, much of the heat—and the fuel or electricity used to create it—is wasted. With the PaceController, energy is consumed in much shorter pulses, using less energy to reach the same set point and satisfy the thermostat.

The PaceController and Heat Pumps The PaceController is very effective on both the compressor and supplementary heat components of heat pumps. In the cooling cycle, the PaceController works as in other cooling applications. In the heating cycle, the run time for the compressor function is increased to reduce reliance on less-efficient supplementary heat. A second PaceController on the supplementary heat unit then works as in other heating applications.

For example, natural gas and oil furnaces may heat their combustion chambers to temperatures of hundreds of degrees Fahrenheit, but the water used for heating may only need to be heated to 140°F—while the controlled-space thermostat is satisfied at a much lower air temperature of perhaps 70F! Similarly, electric resistance heating units are energized longer than necessary to meet air-temperature thermostat set points.

The PaceController establishes an optimal pace that allows more efficient heat transfer, boosting the overall efficiency of the unit. Very warm, but not overheated, temperatures are reached consistently over time. And while the burner or electric-resistance elements are consuming no energy, the system's circulating fans or pumps continue to heat the space as intended.
