S661 Number of EC Fans—Sets the unit of number of EC fans. This parameter is selectable 

between 1 and 5. The factory default is 3.
S662 Inlet Ring K-Value—Sets the inlet ring K-Value. This parameter is selectable between 1 and 

999. The factory default is 480.
S664 Results:—Read-only string that describes S665 through S668.
S665 DP Transducer Low—Shows the status of the low differential pressure transducer in both 

inWC and Pa after it’s setup at S659. 
S666 DP Transducer High—Shows the status of the high differential pressure transducer in both 

inWC and Pa after it's setup at S660.
S667 Actual DP Signal—Shows the actual differential pressure transducer percentage.
S668 Calculated Airflow—Shows the calculated airflow based on the low, high, number of EC fans 

and the Inlet Ring K-Value settings.

Up to four static pressure transducers may be programmed on Screens 7 and 8. Four static pressure 

transducers are shows in Figure 155 for simplicity. Transducer information will be hidden if a device 

has not been configured on SP# Reading from. 
SP# Reading from—Sets the analog input that will be used for the static pressure transducer. This 

parameter is selectable from None, Ana In 1, Ana In 2, Ana In 3 and Ana In 4. The user may also 

choose to select Network. This setting allows the unit to operate based on a shared static pressure 

value across the U2U network. This setting does not required a static pressure transducer connection 

at the unit. The default is none.
SP# Unit of Measurement—Sets the unit of measure that will be used for the static pressure 

transducer. This parameter is selectable in inWC or PA. The default is PA.
SP# Transducer Low—Calibrates the static pressure transducer; sets the value displayed at the 

starting point of the analog input signal. This parameter is selectable from 0-9.999 inWC or 

0.0-2491.0 Pa. The default is 0.000 inWC or 0.0 Pa.
SP# Transducer High—Calibrates the static pressure transducer; sets the maximum value 

displayed, or end point, of the analog input. This parameter is selectable from 0-9.999 inWC or 

0.0-2491.0 Pa. The default is 2.005 inWC or 500.0 Pa.
Actual SP# Signal—Shows the current static pressure based on low and high settings.
Aggregation Method—Up to four different analog inputs can be configured for static pressure. The 

aggregation method defines if the resulting pressure is the Average, Maximum or the Minimum of all 

connected sensors.
Aggr. Unit Static—Displays the unit static pressure based on the Aggregation Method setting.
Network Static Pressure—Displays the maximum or average U2U network static pressure of all 

devices connected in the group. The maximum or average reading is based on the value programmed 

in Service Menus>System / Setpoints, S197 SP Teamwork / Network Mode.
