Set the desired separation of the ventilation stages here, and also the desired differential. The separation is the 
total number of degrees that separate each stage of operation. Once an output or a stage has been activated the 
differential is the amount of temperature change required that the will cancel the operation of that stage or output. 
This setup is not applicable to “PAD VENT”.

Use this selection to enter a reference temperature for the vent system. For example, select the outdoor sensor, 
then enter a minimum and maximum reference temperature, and a minimum and maximum ventilation position.  
The Procom will then constantly adjust the ventilation position based on the outdoor temperature.
