ECS 2M
SECONDARY FUNCTIONS
If the ECS is equipped with an optional humidity
sensor, 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 a new
minimum speed set by secondary function (3). The fan
operates at this speed as long as 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 for the fan is reached. The
humidity level is adjusted 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.
