ADJUSTMENTS & CALIBRATION 
ADJUSTMENTS 
Set the following adjustments as specified on job drawing or 
as required. 
TEMPERATURE SETPOINT ADJUSTMENT 
Integral setpoint adjustment is provided on the R7500C. 
When it is desired to use a remote setepoint adjustment, set 
the integral setpoint adjustment knob to the same 
temperature as the top end of the remote setpoint scale. 
When using the 14002385-008 remote setpoint assembly, set 
the integral setpoint knob to REMOTE. Calibration of the 
remote potentiometer will then be correct. 
PROPORTIONAL BAND (PB) ADJUSTMENT 
This adjustment indicates the change in temperature required 
at the sensor to move the final control device (i.e., valve, 
damper) from one extreme position to the other (full on 
to full off). The controller has the highest gain with the lowest 
PB setting.
