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)
