Single Setpoint found in traditional HVAC systems often restricts comfort
Standard Automatic Mode offers only one setpoint to the user. This would often prove problematic as the comfort of the inhabitant would be influenced by not only the space temperature but also the temperature of the incoming air from the air conditioning system. One setpoint with warm or recirculated air would be comfortable; however, the same setpoint with cool circulated air would feel uncomfortable. Add to this the requirement for the changeover from heating to cooling needing a deadband to prevent cycling and you would end up with a sudden drop in temperature once the mode changes.
Dual Setpoint is the next generation in comfort and energy consumption control
Dual Setpoint offers a solution to this issue by allowing a different heating and cooling setpoint with the system changing mode in between the two setpoints. This control is also ideal for large open spaces where a number of occupants are present with different comfort requirements.
By introducing a deadband between the heating and cooling setpoints, energy savings are offered by preventing over-heating and/or cooling the space.
Dual Setpoint – now built-in to City Multi Systems for ease of use
Previously a high-level BMS or additional controls were required to achieve this level of comfort. However, now this functionality is inbuilt in Mitsubishi Electric City Multi VRF and HVRF Heat Recovery Systems.
