4.5.5.5.1 Static Pressure PI Status

Figure 4-50. PI status screen.
The Static Pressure PI Status screen only appears if your unit is configured for static pressure control. From this screen you may
view the static pressure setpoint and dead band and you may view the proportional and integral values controlling fan speed.
The current operating static pressure and proportional fan control output signal are displayed at the bottom of the screen.
If you need to adjust the static pressure PI control values, you must access the Factory level menu. Contact Tech Support (See
Section 6.0) for the password that allows access to the Factory menu and for guidance on setting the PI control values.

4.5.5.5.2 Temperature Zone Setup

Figure 4-51. Temperature zone setup screen.
If your unit is configured for zone temperature control, Blower>Temp Zone display screens are available for the upper, middle, and
lower fans. These screens allow you to adjust minimum and maximum fan speed settings and modify the fan speed proportional/
integral (PI) control response parameters. The variable dampening value, used with Variance From Average fan speed control (see
Section 4.4.4.1), adjusts the effect of the variance on the final fan speed.
