CBT-STAT and CBT-STAT-H
WHAT ARE CBT-STAT AND CBT-STAT-H?
The CBT-STAT and CBT-STAT-H provide dedicated, visually
appealing Room Control displays for use with CBV and CBT
Unitary Controllers.
Both displays allow the user to view and adjust selected
7parameters within the controller to which they are connected,
and each has an integrated temperature sensor. The CBT-STAT-
Halso has an integrated humidity sensor.
While the display can be used for local control, the CBT12iVAV
and CBT14 Unitary Controllers can be easily integrated into the
Cylon Controls BACnet system architecture.
By default the CBT-STAT and CBT-STAT-H operate in User mode
–see User Mode on page 8 for details.
The CBT-STAT or CBT-STAT-H can be put into Engineering Mode,
allowing the display to be used as a commissioning tool,
adjusting preset points in the Unitary Controller’s default
strategy. See Engineering Mode on page 12.

How to adjust the Temperature Setpoint
If the Controller’s Strategy has been configured to permit it, the user can adjust the Temperature setpoint or occupancy status.
•Press any button so that the temperature setpoint is displayed on the second line, with a flashing unit symbol.
•Press the up button or down button to adjust the setpoint value by the span defined in the Controller’s configuration,
until the desired temperature setpoint is displayed.
•The right button can also be used to request the Strategy to override the schedule and force occupancy mode. Permit
Occupancy Override must be enabled in the controller configuration.
Operation Mode
At the bottom of the display there is a line of icons that give information about the current operation of the
CBT12iVAV or CBT14 Unitary Controller’s Strategy:
Indicates that the controller is operating in ‘heating’
mode.
Indicates that the controller is operating in ‘cooling’
mode.
Indicates that the controller strategy is currently
operating in ‘occupancy’ mode.
Indicates that functions of the Controller Strategy
are in manual override mode.

USING THE ENGINEERING MODE MENUS
When the correct password is entered, the Engineering Menu page line will be displayed. This is indicated
in the display as follows:



The 1st line (large digits) shows the Page number and Line number of the commissioning parameters (see
Available parameters on page 14).
The 2nd line (small digits) shows the label for the parameter addressed by the current line.
Navigating through the Engineering Menus
To scroll through the lines on the current page, use the the up and down buttons (short press).
To navigate to a different page, use the right and left buttons (short press).
Editing a parameter
To view or edit the value of the parameter on the current line, press and hold (“long-press”) the right button .
The 2nd line (small digits) will change to show the current value for that parameter, with either the right-
most character (when the value is a number) or the whole text (when the value is an option label) flashing.
•Press the up button or down button to change the value of the flashing digit or label.
Note: In the case of digits, this is not a simple change to the digit itself, but an addition or subtraction
(from the full parameter value) of the value represented by that specific digit.
For example, if the value is +127, then the left-most digit (“1”) represents 100. If that digit is
selected, then the down button will first change it to +027 (subtract 100 from 127), then
another press of the Down button will change it to -073 (subtract 100 from 27).
•Use the left and right buttons to move between digits
•To reset the parameter to its default value, press and hold the left button
•To apply the edited value, press and hold the right button

CBT-STAT and CBT-STAT-H
BALANCING PROCEDURE - CBV-2U4-3T(-N)
Zeroing Airflow sensor
The CBV-2U4-3T(-N) comes from the factory with the airflow sensor zeroed. To compensate for possible air
leakage around the damper, users are able to zero the airflow sensor in the field. To zero the airflow sensor,
users will need to do the following:
1. Drive damper to the closed position by enabling DampCloseMan (P4L01).
2. After damper has fully shut, set TABPriAirZero (P4L03) to on.
After 10 seconds the TABPriAirZero (P4L03) will be automatically set back to off and the airflow sensor will now
be zeroed.
Be sure to disable DampCloseMan (P4L01) when finished with this step.
Airflow Calibration Procedure
This section provides information on the Airflow sensor calibration procedure of the CBV-2U4-3T airflow sensor
using both Flow/K and K select in the VAV Flow Calculation firmware block
Using Flow/K
1. Set KfactSelect (P4L09) to TRUE .
2. Set Max cfm flow at TABPriAirMaxStpt (P3L06).
3. Set to DamperMaxMan (P4L13) to TRUE .
4. Allow airflow PriAirFlowCV (P4L06) to reach TABPriAirMaxStpt (P3L06). Let damper modulate until
airflow balances out.
5. Enter balancers airflow reading in CFM in MeasuredFlow/K (P4L10) FactorSelect.
6. Again, allow airflow PriAirFlowCV (P4L06) to reach TABPriAirMaxStpt (P3L06). Let damper
modulate until airflow balances.
7. Repeat as necessary.
8. Calculated K factor can be read at KFactorOut(P4L05)
9. Set DampMaxMan (P4L13) to FALSE when complete.
2 point balancing with minimum flow can also be achieved by doing the following:
10. After balancing system to the maximum air flow, Set min cfm flow at TABPriDbandStpt(P3L07)
11. Set DampMinMan (P4L14) to TRUE
12. Allow airflow PriAirFlowCV (P4L06) to reach TABPriDbandStpt (P3L07)
13. Enter balancers airflow reading in CFM in MeasuredFlow/K (P4L10)
14. Again, allow airflow PriAirFlowCV (P4L06) to reach TABPriDbandStpt (P3L07)
15. Calculated K factor can be read at KFactorOut (P4L05)
16. Set DampMinMan (P4L14) to FALSE when complete.
Using K Select
1. Set KfactSelect (P4L09) to FALSE .
2. Set MeasuredFlow/K (P4L10) to unit manufacturer K-FACTOR
3. Calculated flow can be read at PriAirFLowCV (P4L06)

MAN0120US rev 16 © Cylon Controls Ltd. 19
BALANCING PROCEDURE –CBT12iVAV
This method will auto-calculate and set the K factor P4L08 TABPriKFactor (A214).
To utilize this feature, perform the following steps on Menu Page 4: Primary Balancing.
Note: Each parameter is shown below with its Menu page and line number, its Parameter Name and the
associated (Setpoint Number)
1. After determining what the maximum CFM setpoint is going to be for the VAV box, set 
TABPriAirManMode (D204) to .
2. Note the value in  TABPriManStpt (A218).
3. Wait for the value of  PriAirFlowCV (A194) to stabilize, then:
•If the value of  PriAirFlowCV (A194) reaches the value noted in step 2, get a hood
reading at the diffusers to get the actual CFM of the VAV box.
•If the value of  PriAirFlowCV (A194) doesn’t reach the value noted in step 2, set 
TABPriManStpt (A218) to a value below the value reached by  PriAirFlowCV (A194) as a
reference point.
4. Set the  TABPriHoodAtMax (A245) to the actual CFM reading that was recorded utilizing the
hood.
5. Set the  TABAutoCalKfactor (D151) to . It will stay  for 4 seconds then automatically be
set back to . This will automatically set the  TABPriKFactor (A214) internally, through the
Strategy calculating the required K factor. It will also set the  TABPriAirManMode (D204) to
, and the calculated  EffPriAirFlowStpt (A197) will go back to normal operation.
Note: When setting the  TABPriAirManMode (D204) to , it will stay on until the time entered
on point TABPriAirManModeTimer (A217) has expired, unless  TABAutoCalKfactor (D151) is
set to . The default for TABPriAirManModeTimer (A217) is 600 seconds or 10 minutes.
