calibrating a Lawler 804 TMV

in Domestic Hot Water
We have a newly-installed Lawler 804 TMV serving 64 apartments. It was plumbed with a bypass - normally valved off, but in the event we need to service the TMV, we have the ability to deliver hot water straight from the tanks. When we close the bypass & return to using the TMV, does anyone know if we'll need to re-calibrate the thermostat spring? Thanks
