Energy management Is the process of controlling, monitoring and conserving waisted energy in a residential or commercial space. The Cello system allows home owners to automate the use of their home thermostat to eliminate waisted energy consumption. Cello can achieve this by simply lower the setpoint temperature on heat source thermostats or raising the setpoint temperature on cool source while an area is unoccupied. Savings with Cello is just a touch away, set your desired setpoint temperature and just let Cello do the rest.
