Never apply line voltage to any of the connections.
WARNING
When operating a ThermoFlex7500-10000 with the remote
sensor enabled ensure the chiller's response to lowering the
setpoint does not result in operation below 10°C process
temperature. Operation below 10°C requires the use of
50/50 EG/water or 50/50 PG/water.

Remote Sensor Calibration
Figure C-6 Remote Sensor
Calibration Loop
This procedure requires a running chiller and a calibrated reference thermometer.
Note If it is more convenient, perform the low-end calibration before doing the
high-end.
Do not pick calibration points that are outside the safe operating limits of the uid
in your application. For example with water, 40°C and 5°C are typical high and low
calibration points.
Place the remote sensor and a calibrated reference thermometer in the high
temperature remote reservoir. Ensure the uid temperature is stabilized.
Press the
key and the controller will display rtd H. Press again and the
controller will ash between rtd H and the temperature.
Use the arrow keys to adjust the temperature to match the reference thermometer.
Press the
key again to accept the value.
Save calibration
Do not save calibration
Place the remote sensor and calibrated reference thermometer
in a low temperature reservoir. At the rtd L (low-end
calibration) display repeat the procedure.
After the low-end calibration is accepted StorE is displayed.
Press the up arrow to accept the calibration, press the down
arrow key to not accept it.
Note After pressing the up arrow button at the StorE
prompt wait several seconds before proceeding to ensure that
a bad calibration message (Er 16) does not appear. Premature
use of the keypad after pressing the up arrow may cancel the
bad calibration error message.

Appendix D NC Serial Communications Protocol
Note Appendix D assumes you have a basic understanding of communications protocols.
Never apply line voltage to any of the connections.
Connect your PC to the applicable connector on the rear of the chiller. Use the Setup Loop,
see Section 4, to enable serial communications.
Note Keypad operation is still available with serial communications enabled.
• SEr is used to enable/disable and to congure
serial communications.
Range:
oFF, rS232, rS485 Default: oFF
This display depends on your chiller
configuration, see Section 4.

• BAud is used to select the baud rate (speed) for serial
communications.
Range: 9600, 4800, 2400, 1200, 600, or 300 bits per second
Default: 9600
• dAtA is used to display the number of data bits.
Range: Fixed at 8
• StoP is used to indicate the number of stop bits.
Range:
2 or 1 Default: 1
• PAr is used as a means to check for communication errors.
Range:
even, odd, or none Default: none
• u id (chiller id) is used in RS485 only. Identies devices
connected to the RS 485 port.
Range:
1 to 99 Default: 1
Note: To prevent data errors limit the number of chillers to 32.
