Example:
ECW sensor raw temp reads 32.6 °F
ECW temperature offset must be congured to -0.6 ^F (32–
32.6 = -0.6)
• Step 3: Congure the sensor offset
In temperature calibration screen, set the corresponding
sensor temperature offset calculated in step 2.
Note, the offset cannot exceed +/- 2 ^F.
Example:
ECW temperature offset must be congured to -0.6 ^F (32-
32.6= -0.6)
• Step 4: (optional) Verify that the sensor offset is
congured correctly
Verify the following:
- Sensor raw temp has not changed.
- Sensor temperature offset now shows the congured
value.
- Sensor control value is calibrated, and now shows 32 °F.
Example:
“ECW sensor raw temp” still reads 32.6 °F
“ECW temperature offset” now shows -0.6 ^F
“Entering Chilled Water” now shows 32 °F.

5.28.1 - ISM Calibration on J8B 4-20mA Output
• Step 1: Input a test output mA value on the touchscreen
UI
The controller will make ISM output this mA value.
• Step 2: Input the actual reading of mA value from VFD
or mA meter
• Step 3: Recalculate calibration factor
Calibration Factor = 1000 * (Actual Reading mA -
output mA)
Range: 0-2000.
5.28.2 - ISM Calibration on J6 0-10v Input
• Step 1: When chiller is running, record the VFD feedback
voltage and the actual reading on ISM.
• Step 2: Shut down the chiller, enable ISM Calibration
• Step 3: Input the VFD feedback voltage
• Step 4: Input the actual reading of ISM
• Step 5: Recalculate calibration factor
Calibration Factor = 1000 * (VFD feedback voltage / ISM
actual reading voltage)
Range: 800-1200

The purpose of the alarm email is to send e-mails to service
for remote maintenance.
A service configuration table EMAILCFG is used for
network properties conguration. Once the EMAILCFG
table conguration is changed, a test email will be sent for
checking conguration.
This task is checking the status of alarms. Once there is any
alarm switches on, it would send the email with relative
information. When all alarms go back to normal, an e-mail
would be sent too.
The e-mail provides the unit description and location stored
in the CTRL_ID table.

This prognostic function is designed for service trouble
shooting, can be access from Alarm Menu. The prognostic
function enables the service engineer to resolve the problem
before they affected the operating efciency and the chiller
bottom life.
The following functions could be active only if the prognostic
function is enabled (prog_en=YES)
The following screen is designed for prognostic. For each
items, there are three different colors of trafc lamps to
indicate the status. Green lamp indicate it is normal, red
indicate there is problem and yellow lamp indicate it is near
the problem region.
