Temperature/Humidity Setpoint
Only if ordered with the Temperature/Humidity Sensor:
The Setpoint screen allows you to select the method of control for your fans, as well as the
desired temperature or humidity setpoint if the optional sensor is installed.
Set Point: Displays the temperature or humidity threshold. The plus adjusts the threshold
higher; the minus adjusts the threshold lower.
Mode Selection: Allows you to choose between manual mode, temperature mode and humidity
mode. Manual mode allows you to control the fan from the home screen. Temperature mode
runs the fan according to the speed and direction set on the home screen once the measured
temperature is greater or less than the set point temperature (depending on mode selected).
Humidity mode runs the fan according to the speed and direction set on the home screen once
the measured humidity is greater than the set point.
Temperature Reading: Displays the ambient temperature. Will read “BAD TEMP READING” if
there is no sensor connected.
Humidity Reading: Displays the ambient humidity. Will read “BAD HUMID READING” if there is
no sensor connected.
Left Arrow: Navigates to the Home Screen.
Change Units: Changes the Temperature Reading and Set Point between Fahrenheit and Celsius.
Right Arrow: Navigates to the Fan Select screen.
