Step Display Description Values
F6
Air flow K factor:
Display shows
“adjust airflow kfactor vnom” and the value of the k
factor or the V nominal according to your pressure sensor selection
(‘’PrSd’’ or ‘’PrSa’’ selected at step #32, 33 or 34)
PrSd …V = k√∆P when ∆P=1 (10.00V)
PrSa … Vnom =10.00V
Please select the desired value of k factor or the V nominal.
Range: 100 to 9995
Increment: 5
Default value: 1200
F7
Minimum cooling airflow:
Display shows
“minimum cooling airflow” and the value of the minimum
airflow in cooling.
Please select the desired value of the minimum airflow in cooling.
The minimum value is restricted by the maximum value. (step #F8)
Range: 0 to maximum cooling airflow
Increment: 5
Default value: 100
F8
Maximum cooling airflow:
Display shows
“maximum cooling airflow” and the value of the maximum
airflow in cooling.
Please select the desired value of the maximum airflow in cooling.
The maximum value is restricted by the minimum value. (step #F7)
Range: minimum cooling airflow to
k factor or V nominal
Increment: 5
Default value: 1000
F9
Minimum heating airflow:
Display shows
“minimum heating airflow” and the value of the minimum
airflow in heating.
Please select the desired value of the minimum airflow in heating.
The minimum value is restricted by the maximum value. (step #F10)
Range: 0 to maximum heating airflow
Increment: 5
Default value: 100
F10
Maximum heating airflow:
Display shows
“maximum heating airflow” and the value of the maximum
airflow in heating.
Please select the desired value of the maximum airflow in heating.
The maximum value is restricted by the minimum value. (step #F9)
Range: minimum heating airflow to
k factor or V nominal
Increment: 5
Default value: 1000
F11
Enable or disable airflow balancing:
Display shows
“enable airflow balance”.
You can enable or disable the balancing airflow function.
If you do not need to balance system, select No. You will leave the
balancing menu and return to operation mode.
If you want to balance system, select YES. In this case, you will leave the
balancing menu and return to operation mode if no button is pressed for
30 minutes, changed values will be saved.
Default value:
Disable (No)
F12
Minimum airflow calibration:
Display shows
“minimum airflow” and the value of the minimum airflow
detected by the pressure sensor.
The thermostat will send a signal to the actuator close the VAV boxe at
minimum airflow. When the value on thermostat is stable, you can adjust
the calibration of the sensor by comparison with the reading on a
manometer or a balometer.
If you can’t stabilize the system, you will need to increase the filter value.
(step #F4)
Range: 0 to k factor or V nominal
(max. offset ± ½ value)
Increment: 1
F13
Maximum airflow calibration:
Display shows
“maximum airflow” and the value of the maximum airflow
detected by the pressure sensor.
The thermostat will send a signal to the actuator open the VAV boxe at
maximum airflow. When the value on thermostat is stable, you can adjust
the calibration of the sensor by comparison with the reading on a
manometer or a balometer.
If you can’t stabilize the system, you will need to increase the filter value.

Come back to step #F11
Range: 0 to k factor or V nominal
(max. offset ± ½ value)
Increment: 1
