Temperature 
Setpoint 

Allows the temperature 
setpoint for the occupied and 
standby modes to be changed 
via the network.  It is used to 
reset the temperature rather 
than change them.

Setpoint 
Offset 

Shifts the temperature control 
point via the network.  It is 
typically bound to a 
supervisory node providing 
outside air temperature 
compensation or to an 
external wall diffuser having a 
relevant setpoint knob.  
Operates only on occupied 
and standby setpoints.
