Start value 1 > Start value 2
Start value 1 < Start value 2
The supply air control with room air limitation is based on the same control
principle as the supply-air limited room air control. Only here the setpoint shifts
to the opposite direction, because it works on the basis that the supply air is
colder than the return air.
If the room temperature exceeds the start temperature 1
➋a, the supply air
temperature setpoint is reduced.
With the setting of a second start value
➋b the supply air setpoint is raised
when the room air temperature falls due to less thermic charge. By this, cooling
capacity is reduced and energy is saved.
If start value 1 is lower than start value 2, the setpoint is shifted according to
start value 1 for an actual value between both start values.
If the room humidity (only for rel. humidity) drops below the starting humidity
entered
➍, the supply air humidity setpoint is increased.
