does any one know if this product below actually save without raising the space temp.

The ECO3TM or ESMTM is installed between the primary controller and the compressor in a customer's HVAC-R system. Smartcool's technology continuously monitors the compressor cycles to identify opportunities for energy savings. How savings are achieved is dependent on the nature of the customer's equipment.
Cycle Optimization

  • Smartcool's technology dynamically adjusts the length of each cooling cycle in order to help the compressor operate more often within the most efficient suction pressure band.
  • This solution is used by thousands of packaged air conditioning, refrigeration and heat pump systems around the globe.
Load Modulation

  • Smartcool's technology works within existing control methodologies to modulate load for periods of time during the cooling cycle.
  • This solution is used by thousands of chilled line systems worldwide.
With either solution, the technology will automatically pull itself out of the circuit when necessary to prevent over-cycling or temperature increases. Smartcool's solutions do not impact existing manufacturer warranties
