The ecWizard control saves energy a number of ways similar to an existing DDC energy management automation system.

• (DDC energy management automation system is an all electric computerized monitoring control system that is currently used to replace existing/or new pneumatic systems when energy savings are required.) The ecWizard allows an economical alternative to ripping out existing pneumatic control systems.
• As we previously discussed existing pneumatic control systems do not have the ability to start or stop the air-conditioning and heating for individual thermostatically controlled zones.  Large fan systems utilizes a time clock where entire floors or building are shut down or started to accommodate various occupied/unoccupied requirements.  By individually customizing timeclock schedules for each room thermostat we can save a large amount of energy money.
• The biggest energy savings come from simply shutting the air, cooling and heating off, just like the lights are shut off when someone leaves the area. The ecWizard control can shut the air off to individual zones.
• Limiting the set points prevents the thermostat from being left at 50 to 90°. It seems even if there's a locking cover on the thermostat somehow, someway, someone is able to adjust the set point.  For each degree that you're able to raise/lower the thermostat represents approximately 3% savings of the mechanical costs for that area or zone. The ecWizard control can limit the pneumatic thermostat from going below 70° and above 75°.
• The ecWizard control can also establish a dead band instead of having one set point. You can establish set points limits for heating and cooling. Existing pneumatic thermostats typically have one set point as an example 72° but with the ecWizard control you can establish a heating setpoint of 70°(off below) and a cooling setpoint 74°(off above) having a dead band of 3°.  The bands of 4° and 5° represent additional savings.  With dead band type control the room is heated to 70° than naturally increases in temperature to 74° before energizing the costly cooling system.
• Conference rooms are quite often left unoccupied with air-conditioning and heating running for no reason.  The conference room’s schedules can be programmed to allow air conditioning and heating prior to occupancy. If you seldom use the conference room or do not want to follow a scheduled regiment then you simply have to push the sensor override button to obtain air conditioning and heating for a couple of hours.  The ecWizard control also enhances the temperature of the conference rooms by limiting the cold temperature extremes that are inherent with turning off the lights in unoccupied areas.
• Each The ecWizard controller can have its own individual schedule allowing you to shut off the air, cooling and heating when unoccupied.  Buildings with varying occupancies have a much greater opportunity for savings.  Most buildings have 10% to 30% of unoccupied space daily.  Having the ability to totally turn off the air from 10% to 30% of your facility each day is a tremendous savings. It's not uncommon to find some facilities that have to run their complete building or floor on a Saturday just to accommodate a small percentage of occupants.
• Holiday schedules can be individually implemented and customized throughout the facility.
• Some areas of the facility people arrive earlier or later and have different heating requirements than other areas.  This is where optimize start programs can vary the start times according to a particular areas ability to heat up.  Some areas of the facility may require 4 to 6 hours of pre-heating time where other areas may only require an hour or less of pre-heating time.  Quite often some areas have preheated and are starting in the cooling process prior to occupancy.  The optimize start programs can eliminate this costly and daily waste of energy.  Optimize start programs can learn a particular zone's ability to heat up and then start the heating process just in time for the room temperature to meet its setpoint for the actual occupied time.
• The The ecWizard controller and software can be utilized to communicate (optional) with the rooftop/main HVAC system to eliminate the guesswork with trying to provide the appropriate temperatures and volume to the condition spaces.(This important communications not only saves money but helps protect the expensive Rooftop/Main HVAC system from constant breakdowns and repairs due to running in low load conditions.)
