SECONDARY FUNCTIONS
RELATIVE HUMIDITY SET POINT
If the ECS is equipped with an optional
humidity probe, this setting regulates the
humidity level of the room. The humidity setting
affects the operation of Fan 1 only. When the
humidity level of the room exceeds the relative
humidity setting, Fan 1 runs at new minimum
speed. The speed that Fan 1 operates at, is
governed by the ambient humidity of the room.
This turn may cause the fan to increase to a
speed 30% higher than the Fan 1 minimum
speed set by primary function (2). The fan
operates at this increased speed for as long as
the ambient room temperature is below the
main set point. When the temperature of the
room is greater than the main set point
temperature the fan speed increases until the
maximum speed as been reached. The
humidity level is adjustable in 1% increments
from a minimum setting of 30% to a maximum
setting of 80%.
Adjusting the relative humidity level:
•
rotate the Selector dial to position (12),
•
rapidly rotate the Adjustor dial back and
forth to enter secondary function mode,
•
rotate the Selector dial to position (1),
•
rotate the Adjustor dial counterclockwise to
decrease the humidity setting, clockwise to
increase it.
The humidity setting is displayed on the ECS.
