Space Static Pressure Setpoint
0.5 to 4.5 vdc
0.03 to 0.30 IWC
Supply Air Pressure Setpoint
0.5 to 4.5 vdc

(VAV units only)
Note: 1. Input voltages less than 0.5 vdc are considered as 0.5 vdc input signal is lost, the setpoint will
“clamp” to the low end of the setpoint scale. No diagnostic will result from this condition.
2. Input voltages greater than 4.5 vdc are considered to be 4.5 vdc.
3. The actual measured voltage is displayed at the HI.
