Carrier Aero 39MN Series Installation, Start-Up And Service Instructions Manual page 142

NOTES:
1. All conductors are no. 22 AWG (American Wire Gage) minimum.
2. Install jumpers if fire/smoke detector, low limit thermostat, or high pressure switch are not required.

Static Pressure Transducer
*Acceptable transducer output voltage ranges are 0-10 vdc, 0-5 vdc, and 2-10 vdc. Default sensor range is 0-10 vdc from factory. Use parame-
ters 4008 to configure sensor low voltage and parameter 4009 to configure sensor high voltage.
NOTES:
1. All conductors are no. 22 AWG (American Wire Gage) minimum.
2. Install jumpers if fire/smoke detector, low limit thermostat, or high pressure switch are not required.
3. Program static pressure control set point using parameter 4011 in volts vdc.
