To turn the software lockout back On:
1. Set lock values back to previous setting. See “Remove Software Lockout” above.
Controller Configuration
The Watlow PM Temperature and Humidity Controllers have been configured at the
factory. Copies of the Watlow Configuration records are included at the end of this
section.
Offset Calibration (Temp/Humidity)
It may be necessary to calibrate the temperature or humidity controllers to match an
independent temperature or humidity sensor. To do so, follow the next few steps.
1. Perform the “Remove Software Lockout’ procedure in this section.
2. Suspend an independent, calibrated sensor(s) in the center of the interior chamber.
3. Allow approximately 30 minutes for the environmental chamber to stabilize.
4. Press Up and Down Arrow keys simultaneously for 3 seconds. The word “OPEr”
appears in the lower display.
5. Press Down Arrow until “Ai” appears in the upper display.
6. Press the Advance key until “i.CA” appears in the lower display. Press Up or Down
Arrow key to either add or subtract an offset value. This value is the difference
between the actual value shown on the controller, and the reference sensor value.
7. Press the Infinity key until the display reverts to normal operation.
8. Perform the ‘Restore Software Lockout’ procedure in this section.
Do not re-configure the controller without first consulting the Technical Services
department.
NOTE
Recalibration of setpoint is recommended when different climate classes are used for the
applications with and without light function.
