Calibration
The ITA-6 adjusts the opening of air inlets according to the ventilation
stages provided by the environment controller. The calibration allows
ITA-6 units to detect how many On/Off and variable stages the environ-
ment controller uses.
When the calibration is launched on the PRIMARY ITA-6 unit, the environ-
ment controller enters in test mode and starts simulating the room tem-
perature. The controller increases the simulated room temperature in or-
der to activate all of its ventilation stages. Each time a stage is activated,
a reference point is added to the ITA-6.
BEFORE CALIBRATING THE ITA-6:
•
It is preferable to calibrate the ITA-6 while the room is empty be-
cause the calibration will cause the activation of all fan stages.
•
Be sure that the circuit breakers at the service panel and all other
protection devices are in a position such that the fans can be acti-
vated.
•
Select the season you want to program with internal switch #3.

CALIBRATION SETTINGS:
1. Select
CALIBRATION
using the function selector.
2. Press and hold the push-button of the primary ITA-6 unit for 2 sec-
onds to start the calibration.
3. Once the calibration is launched, you must press and hold the push-
button for 2 seconds on all ITA-6 slave units within the next 30 sec-
onds.
4. After 30 seconds, the environment controller enters in test mode
and starts simulating the room temperature. The simulated room
temperature gradually increases for ITA-6 units to detect the num-
ber of On/Off and variable ventilation stages in use.
5. After the environment controller has reached the start tempera-
ture of its last ventilation stage, press and hold the push-button of
the PRIMARY ITA-6 unit for 2 seconds to end the calibration. You
can also wait for the environment controller to reach 120°F (49°C)
– the calibration will automatically end at that moment. One refer-
ence point per ventilation stage will then be added to each cali-
brated ITA-6.
6. Refer to the programming chapter to assign an inlet opening to
each reference point.
