Honeywell UDC2500 ユーザーズマニュアル

This selection results in performance tuning over the full range utilizing both Heat and 
Cool outputs to acquire blended tune values that are then applied to both Heat and Cool 
tuning parameters.  Both PID sets are set to the same values. 

Step 

Configure LSP1 

 

Until SP (Local Setpoint 1) shows 
in the lower display. 

 

or

 

Until the Setpoint is to the desired 
value. 

Switch to 
“Automatic” Mode 

 

Until the “A” indicator is lighted (on

Select “DoSLOW” or “DoFAST” in 
lower display. 

Tuning in operation 

 

Upper display will flash “TUNE” as 
long as ACCUTUNE process is 
operating.  When process 
completes, tuning parameters are 
calculated and lower display will 
show “NoTune” prompt. 

When DUPLEX has been configured for MANUAL.  This selection should be used when 
tuning is needed only for the HEAT zone or only for the COOL zone but not both.  If 
Local Setpoint 1 is used, then the controller will perform a HEAT zone tune.  If Local 
Setpoint 2 is used, then the controller will perform a COOL zone tune. 

Step 

Configure LSP1 

 

Until SP (Local Setpoint 1) shows 
in the lower display. 

 

or

 

Until LSP1 is a value within the 
Heat Zone (output above 50%). 

Switch to 
“Automatic” Mode 

 

Until the “A” indicator is lighted (on 
controllers with Manual option).
