PROBLEM
Display Not Working
SOLUTION(S)
•
Wires not connected correctly, no signal from transmitter or
common ground. Also make sure the display is plugged in correctly
after mounting.
TEMPERATURE DISPLAY ADJUSTMENTS
The Temperature Display may be adjusted by adjusting the ZERO Potentiometer as shown on the above
diagram. Adjust zero pot until the LCD Display reading matches your sensor if necessary. Do not adjust the
SPAN pot.
SETPOINT CONTROL
Adjust slider at bottom of housing for set point control. Slide to right to increase set point temperature.
Slide to left to decrease temperature control. Units can be setup from factory for Direct Acting (resistance
increases when adjusted to right), or Reverse Acting (resistance decreases when adjusted to right).
OVERRIDE ADJUSTMENTS
Override will be set to Dry Contact.
