RATE DOWN—Rate down value. When 
making a setpoint change, this is the rate at 
which the controller will change from the 
original setpoint down to the new one. The 
ramping (current) setpoint can be viewed as 
SPn in the lower display. 
Entering a 0 will imply an immediate change 
in Setpoint (i.e., no rate applies).
