Maintenance - Carrier TruVu VVTBP-E2 Installation And Startup Manual

Appendix A: TV-VVTBP-E2 Points/Properties
Point Name/Description
Test and Balance
Zero Cal – Closes the bypass damper and waits for the air source to go to the
Off mode before zeroing out the static pressure sensor. This does not occur if
the static pressure is > .05 in. H
Pressure Sensor Cal – Allows you to calibrate the pressure sensor after the
Zero Cal has been performed. To enter a value here, neither the damper nor
the pressure sensor can be locked, the bypass cannot be in LAT mode and the
damper position must be >0% and <100%. The value entered will be the actual
static pressure measured with an accurate static pressure measuring device.
Damper Full Open – Overrides the damper to its full open position.
Automatic Control – Returns the damper to its normal control routines. This
must be activated when you finish using any of the other Test and Balance
commands.
Damper Full Close – Overrides the damper to its full closed position.
Local Sensor Calibration
Supply Air Temperature – Displays the current supply air temperature.
Supply Air Temp Calibration – A calibration offset value to allow the supply air
temperature sensor to be adjusted to match a calibrated standard measuring the
temperature in the same location.

Point Name/Description
Static Pressure – The current supply duct static pressure.
Controlling Pressure Setpoint – The active static pressure setpoint that the bypass
controls to.
Maximum Duct Pressure Setpoint – The Pressure Control Deadband that is added to
the active static pressure setpoint.
Minimum Duct Pressure Setpoint – The Pressure Control Deadband that is subtracted
from the active static pressure setpoint.
