OTC25 P
Operation
OTC25 P PID Temperature Controller
Normal Operation
The factory default display setting of the OTC25 P is for Actual
Temperature 
. The default display may be changed to
setpoint temperature by selecting Setpoint 
at the Default
Display 
parameter selection. When the Default Display is changed to Setpoint, the setpoint temperature may be adjusted
by using the Raise 
or Lower 
keys. The setpoint is adjustable from 0 to 999° F
When the Default Display setting is “Actual” 
, adjustment of the Setpoint may only be accomplished by pressing the
Parameter 
Key momentarily to switch the display to
Setpoint, and then using the Raise 
or Lower 
Keys to change the Setpoint Value. The display will automatically revert back to “Actual” five seconds after the last keypress.
Parameter Configuration
Your OTC25 P controller’s parameter selections are explained on the next page, with default settings shown in Figure 5c.
To enter the configuration menu, press and hold the Parameter key 
for 10 seconds until the display changes to the parameter mode. Press the Parameter key again to index through the avail- able parameters. Pressing the Parameter Key for 3 seconds or allowing 60 seconds of inactivity will cause the OTC25 P to exit the menu system and return to normal operating mode.
