With a Phillips screwdriver, move the end of travel. Fix

it to always keep an opening between 100% and the

minimum desired (50%) in example below.

Note for maintenance : Check glycol circuit pressure before free cooling operation season starts. Run glycol pump
few minutes in manual override during monthly maintenance operation when free cooling is continuously OFF to
avoid possible glycol cristalization. Pump Override function is located in TD7 via Button Settings -> Manual Control
Settings -> Free Cooling Pump Override.

Optional Free-Cooling

If the minimum opening is modifi ed after the fi rst
powering, motor re-calibration is needed to validate the
new operating range. When motor is powered, push
green led button (2). Motor memorizes the new reference
of end of travel position on its signal (2…10 VDC)
