Temperature Band and Differential:
o
The band is the number of degrees above the target temperature in which the
controller's current level of ventilation is satisfactory. The band is factored into account
only when the differential is set to zero. When the average temperature rises above
the band, Element increases the ventilation by one level (after waiting the appropriate
delay time). Element will continue to increase the level of ventilation until the average
temperature falls below the band level or it reaches a level that does have a
differential.
o
A differential is the number of degrees above the target at which the ventilation
increases to a specific level. When the temperature rises to the level set by the
differential, Element increases the ventilation by one level (after waiting the
appropriate delay time).
Make sure that the differential is greater than the band!
Any level's differential of must be greater than the previous level's differential.
However, if a differential is set to zero, the differential remains at the previous
level.
For example, if Level One's target temperature is 75° and the band is 1° (with the
differential set to zero), ventilation increase begins at 76° (Figure 27)
Figure 27: Level One Differential and Band
If the target temperature is 75°, differential is 3°, and the band is 1°, ventilation increase
begins at 78° (the band does not factor in) (Figure 28).
Figure 28: Level Two Differential and Band
However if the target temperature is 75°, differential is 3°, and the band is 1°, the new
Happy Zone is from 78° to 79°.
