This feature also applies when the minimum ventilation speed is activated.
Note that for the compensation to take place, the compensation feature
must be activated by the user. When a compensation is applied to the
minimum speed, the compensation pilot light turns on.
HUMIDITY COMPENSATION
The stage 1 minimum speed can be adjusted automatically as a function of
relative humidity. As humidity increases, the stage 1 minimum speed in-
creases proportionally to compensate for the change. At humidity levels at
or below the humidity set point, stage 1 minimum speed is equal to the
normal uncompensated speed. The user specifies the percentage increase
in minimum speed for a relative humidity equal to the humidity set point +
10%. For example, if the minimum speed is 40% and the compensation
adjustment is 30%, the minimum speed will be adjusted to 70% of full
speed when the humidity rises 10% above the humidity set point. In addi-
tion to adjusting the minimum speed, the humidity compensation feature
also changes the operation of the minimum ventilation cycle: if the control-
ler is operating in minimum ventilation mode when the relative humidity
exceeds the humidity set point, the minimum ventilation fans are operated
continuously rather than cycled.
