Calibration
The TC5-ITA adjusts the opening of air inlets according to the ventilation
stages provided by the environment controller. The calibration allows
TC5-ITA units to detect how many On/Off and variable stages the environ-
ment controller uses.
When the calibration is launched on the PRIMARY TC5-ITA unit, the envi-
ronment 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 TC5-ITA.
BEFORE CALIBRATING THE TC5-ITA:
•
It is preferable to calibrate the TC5-ITA while the room is empty
because 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 selection buttons
2. Press and hold the right-arrow key for 2 seconds on the primary
TC5-ITA unit to start the calibration.
3. Once the calibration is launched, press and hold the right-arrow
key for 2 seconds on all TC5-ITA 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 TC5-ITA units to detect the
number 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 right-arrow key
of the PRIMARY TC5-ITA 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 reference point per ventilation stage will then be added to
each calibrated TC5-ITA.
6. Refer to the programming chapter to assign an inlet opening to
each reference point.
