Bullet Probe Sensor Mounting (C7021N, 
C7023N, C7041N)
The bullet probe sensor is a water-resistant sensor that 
provides a cost-effective solution for surface contact 
temperature measurement of conditioned water pipes, low 
pressure steam or refrigerant lines. These sensors are ideal for 
applications where immersion wells are not practical to install. 
These sensors can also be use to sense air temperature.
WIRING
CAUTION
Erratic System Operation Hazard.
Failure to follow proper wiring practices can 
introduce disruptive electrical interference (noise).
Keep wiring at least one foot away from large inductive 
loads such as motors line starters, lighting ballasts, 
and large power distribution panels.
Shielded cable is required in installations where these 
guidelines cannot be met.
Ground shield only to grounded controller case.
CAUTION
Electrical Shock or Equipment Damage Hazard.
Can shock individuals or short equipment 
circuitry.
Disconnect power supply before installation.
IMPORTANT
1. All wiring must agree with applicable codes, 
ordinances and regulations.
2. Do not mount sensor in incorrect environment.
3. Wire according to the applicable controller 
instructions.
OPERATION AND CHECKOUT
Operation
The C7041 Temperature Sensors are designed for use with 
XL500, XL100, XL50, XL15, XL10, and Honeywell LCBS 
Controllers or any controller requiring 20K ohm NTC 
non-linear input. As the temperature at the C7041 Sensor 
increases, the resistance of the sensor decreases, causing the 
controller to operate and offset the temperature change. 
The C7021 Temperature Sensors are designed for use with the 
TB7600, TB7300, and TB7200 Series Communicating 
Thermostats or any controller requiring a 10K ohm NTC Type II 
input.
The C7023 Temperature Sensors are designed for use with 
WEBs-AX I/O Modules or any controller requiring a 10K ohm 
NTC Type III input.
Checkout
Refer to the applicable controller instructions when checking 
out the complete heating and cooling systems.
To check out the sensors, move the thermostat or remote 
setpoint potentiometer below the temperature of the cooling or 
heating medium. Watch the motor, valve or damper for the 
correct movement.
