Terminal Equipment Controller
1 Auxiliary NO, Occ or St-By = Contact Closed / Unoccupied
= Contact Opened
2 Auxiliary NC, Occ or St-By = Contact Opened /
Unoccupied = Contact Closed
Output to follow directly main occupancy and Fan on
command
Typically used for 2 position fresh air damper applications.
3 Auxiliary NO, Occ or St-By & Fan On = Contact Closed /
Unoccupied & Fan On or Off = Contact Opened
4 Auxiliary NC, Occ or St-By & Fan On = Contact Opened /
Unoccupied & Fan On or Off = Contact Closed

command
5 Auxiliary On/Off Control through auxiliary network
command. The output can be commanded through the

control at the expense of wearing mechanical components
faster.
Range is: 3, 4, 5, 6,7 & 8 C.P.H.
