PROCEDURE STEPS STEDISPLAY
2 Select the restore sengs display.
1. From the CNFG display, press the
∆ or buons
to show the CNFG display.
2. Press the buon to select the CNFG opons.
The display changes to STPT.
3. Press the ∆ or buons to change the display to
RSTR.
Cauon: Choosing RSTR deletes all previously
entered values and returns the controller to
the manufacturer’s sengs. Only the BACnet
communicaons sengs will remain unchanged.
4. Press the buon to select RSTR.
3 Choose the applicaon.
1. Press the
∆ or buons to choose ENGLISH
or METRIC.
Metric The sensor displays temperature in Celsius and
uses metric values for units of measure.
English The sensor displays temperature in Fahrenheit
and uses English values for units of measure.
2. Press the buon to save the entry and advance to
the next funcon.

Secon6:BalancingAirow
Topics in this secon are for control technicians or engineers who will be balancing the airow in the controllers.
The airow balancing procedure described in this secon requires the following items.
• Accurate method to measure airow.
• An STE-8001W36 or STE-8201W36 wall sensor. If the system does not include one of these sensors, temporarily disconnect
the installed sensor and connect an STE-8001W36 as a service tool.
• The engineering design specicaons for the minimum and maximum airow set points.
• Password 2 which is described in the topic Geng started with conguraon on page 14.
Users may change the acve heang and cooling set points without accessing the conguraon funcons. This procedure is
covered in the topic Changing the Room Set Point on page 13.
Note: If the VAV terminal unit is a heat only or cooling only unit, the airow set points for the unused mode must be set within
the range of the mode in use. Failure to set the unused set points correctly will result in unpredictable or erroneous air balancing
sengs. See Set the airow set points on page 19 for the procedure to adjust the set points.
Note: Starng the balancing procedure erases all previous airow correcon factors. The airow readings displayed by the
STE-8001W36 are the actual uncorrected airow readings as measured by the controller.
Tip: Once the following procedure is started, all steps must be completed in order.
