Temperature setback is the act of adjusting the thermostat while you’re not using an office or a building space. In summer, raising the thermostat makes the space warmer but prevents the air-conditioning system from running afterhours, this lowers your electrical bill. In the winter the same act happens but this lowers the temperature afterhours, lower heating bills.
Fan Modes: On: The fan will run continuously. Auto: The fan will run only when the heating or cooling system is on. Circulate: The fan will run at random intervals at least 35% of the time to keep air circulating throughout your building. Without constant movement of air IAQ cannot be guaranteed but again this is not requiring during afterhours, these thermostats will cycle the fan off during that period automatically.
It’s important to provide fresh, healthy air to a building’s occupants. Therefore, when introducing fresh air into a building, how do you exhaust the present air? One method is with an interlocked exhaust fan or Barometric Relief Damper, sometimes they are referred to as Gravity Dampers.
The Result of Positive Building Pressure
As economizer dampers open and close, the amount of outside air entering a building’s space is increased or reduced. However, when forcing more air into the building than can be removed, problems occur. The higher pressure of the building is pushing to get out. Doors standing open, and whistling elevators can result from excessive positive building pressure due to air rushing out the building. A substantial positive pressure differential could result in the excessive loss of conditioned air, leading to increased energy costs. An extreme pressure differential could even damage roof systems.
An economizer is a part of the outdoor system, most often mounted on the roof, of an HVAC system for commercial buildings. As the economizer detects the right level of outside air to bring in, it utilizes internal dampers to control the amount of air that gets pulled in, recirculated and exhausted from your building. This saves energy in the shoulder months, where temperatures are lower than 10 degrees Celsius.
