Force Damper to Minimum when GB(x) ……….…:
The VAVBOX TUC-2R controller damper can be globally forced
to one of several positions with the use of Global Binaries. There
may be times at which the end user will want to have minimum
airfl ow in the conditioned zoned space. Such forced overrides
could include Global binary determinations for troubleshooting,
air balancing, night set back, smoke detection (Remember that the
WCC III is not rated for fi re life safety) etc. On a Global force
mode it will be possible to force multiple VAVZONE boxes open or
closed with a single global command. (Ignores Airfl ow Reading.)
Force Damper to Fixed Damper/Airfl ow when GB(x)..:
The VAVBOX TUC-2R controller damper can be globally forced
to one of several positions with the use of Global Binaries. There
may be times at which the end user will want to have fi xed
airfl ow in the conditioned zoned space. Such forced overrides
could include Global binary determinations for morning warmup,
troubleshooting, air balancing, CO2 reduction, pre-cooling or pre-
heating for a meeting room, smoke detection (Remember that the
WCC III is not rated for fi re life safety) etc. On a Global force
mode it will be possible to force multiple VAVZONE boxes to
a fi xed position with a single global command. (Ignores Airfl ow
Reading.)
Force Damper to Re-Calibrate when GB(x) ………:
The VAVBOX TUC-2R controller damper can be globally forced
to one of several positions with the use of Global Binaries. There
may be times at which the end user will want to re-calibrate the
actuator on the VAVBOX. Such forced overrides could include
troubleshooting and air balancing.
Remember that there may be a mechanical problem with the
actuator or air valve damper, and you should always try to re-
calibrate the actuator before determining if the actuator is actually
bad or not.
Space Temp Sensor Calibration Offset ………….:
There is an option to change the calibration of a thermistor sensor
(Usually due to the position or location of the thermistor sensor)
a few degrees plus or minus from the actual temperature that the
thermistor sensor is actually reading. Acceptable values in this
fi eld are numerical with both positive and negative (+/-) values of
0 to 99. These values are in Degrees Fahrenheit.
Discharge Temp Sensor Calibration Offset ………….:
There is an option to change the calibration of a thermistor sensor
(Usually due to the position or location of the thermistor sensor)
a few degrees plus or minus from the actual temperature that the
thermistor sensor is actually reading. Acceptable values in this
fi eld are numerical with both positive and negative (+/-) values of
0 to 99. These values are in degrees Fahrenheit.
NOTE: If no duct sensor is attached then this will read the
same as the Supply Air Temperature.
