Changeover
Pressure-Dependent VAV systems and 2-pipe fan coils require changeover detection in order to switch seasonal
operation between heating and cooling modes. The TEC supports the following methods for changeover:
automatic changeover using an analog sensor (thermistor), automatic changeover using a binary switch, or remote
changeover from a BAS and manual changeover.
