Changing the Setpoint Thumb Wheel (optional)
Sensors with temperature setpoint control have pre-installed Fahrenheit setpoint thumb wheels.
A Celsius setpoint thumb wheel is included with these sensors. An optional hot/cold setpoint
thumbwheel can be ordered separately.
To change the thumb wheel:
1. Remove the cover by firmly pressing the thumb tab at the bottom of the cover and pulling the
cover away from the back plate.
Note: If present, remove the security screw before removing the cover.
2. Remove the existing thumb wheel by pulling it straight out while holding the circuit board
securely onto the back plate.
3. Rotate the replacement thumb wheel until the stop is opposite the flat portion of the
potentiometer. Push down on the thumb wheel until the ribs touch the potentiometer. After it
is inserted, the thumb wheel should turn freely.
Wiring the Sensor
WARNING
Hazardous voltage!
Disconnect all electric power, including remote disconnects before servicing. Follow proper
lockout/tagout procedures to ensure the power cannot be inadvertently energized. Failure to
disconnect power before servicing could result in death or serious injury.
NOTICE
Equipment damage!
Applying excessive voltage to the sensor will permanently damage it.
To wire the sensor, use the appropriate diagram illustrated in“Wiring Diagrams,” p. 33.
Note: Strip 1/4 inch of insulation from wires before connecting them to the terminal block.
