Confirm that under the ‘sensor installation’ drop down, ‘dsp/bsp/ co2/ai reset’ is ‘installed’. Then, as the building load decreases in the afternoon, the system resets the static pressure back to 1 inch, until finally the system turns off. Static pressure testing normally requires five steps to complete:

As Building Static Pressure Increases, The Controller Will


• to enable duct static pressure sensing, go to the ‘configuration’ menu and under the ‘inputs’ drop down change ‘analog input 16’ to ‘dsp’. Run two 1/4 inch sensing lines (high and low) to the sensing location. • to enable fan control based on duct static pressure

Choose A Static Pressure Sensor That Allows The Hvac Controller To Operate In The Upper Half Of The Sensor’s Normal Operating Range.


Once the static pressure probe is mounted, run vinyl Reliable barometric pressure measurement in all weather. If you are mounting on mechanical equipment with a condenser fan or a building air discharge, mount the outdoor air static pressure pickup port on the opposite end of the equipment.

When The System Turns On, The Static Pressure Is Set To 1 Inch, And As The Building Load Increases, The Static Pressure Is Reset To 1.5 Inches.


Select a mounting location as free as possible from rooftop obstructions. Signal output on the c location should read approximately 0.5v if there is no pressure applied. It mounts directly to the wall or to a standard electrical box.

Static Pressure Sensors Used To Control Vav Fans Shall Be Located Such That The Controller Setpoint Is Not Greater Than 1.2 Inches W.c.


The static pressure will go unchecked, but quite predictable, and will not matter much because the main problem is actually preventing the coil freeze and slugging the compressor. • to enable fan control based on duct static pressure Duct static pressure sensor (sps1) 910117462 1 building static pressure sensor (sps2) 910117463 1 entering air temperature sensor 193414602 1 leaving air temperature sensor 193414602 1 exhaust air temperature sensor 193414602 1 humidistat sensor (units with frost protection) 910190890 1 humidistat sensor support 910194091 1

Paste the data into the box. The signal output should increase These sensors are used to sense static or differential pressure for duct or building pressure measurement.
