Configuring the Sequence of Operation (SeqOpera) - Johnson Controls - 24-9890-1397 - T612DFH-4 - T612DFH-4+PIR - T612DFH-4 and T612DFH-4+PIR Thermostat Controllers with Fan Control and Occupancy Sensing Capability

Choose the appropriate sequence of operation using Table 1 or Table 2. The modes presented are user-dependent on the sequence of operation selected. For two-pipe applications using a changeover sensor, choose the selection option (0): Cooling Only. Changeover occurs between Cooling Only and Heating Only. See Figure 1 through Figure 6 for sequence of operation examples.
