2. Place the temperature sensor in a 32°F (0°C) water solution.
3. Read the sensor raw temperature on the Maintenance
screen.
4. Calculate the offset to be applied as follows:
32 – sensor raw temp (°F)
Example:
ECW sensor raw temperature reads 32.6°F.
ECW temperature offset must be set to –0.6°F
(32 – 32.6 = –0.6)
5. In the Temp Sensor Calib screen, enter the temperature offset
for the appropriate sensor as calculated in Step 4. See Fig. 37.
NOTE: The offset cannot exceed ± 2°F (1.1°C).

6. Verify that the measured temperature value is the same as
the controlled temperature.
ALARM EMAIL
The alarm email function sends automatic email messages to
specified service personnel for remote maintenance purposes.
This function can be set up from the second page of
Configu-
ration Menu
E-Mail Configuration
(EMAILCFG). Subse-
quently if there is an alarm the function will send an e-mail
message. Another message is sent when all alarms return to
normal. See Fig. 38 and 39.
Fig. 38 — E-Mail Configuration Screen, Page 1
Fig. 39 — E-Mail Configuration Screen, Page 2
The alarm task runs periodically. At each alarm task run time, the
status change of each alarm is checked and one email message is
sent to each specified recipient when one or more alarms are
switched on. When all alarms return to normal, another e-mail
message is sent to remote maintenance service personnel.
The e-mail message provides the unit description and location
stored in the CTRL_ID table, available from the CONFIGU-
RATION menu. See Fig. 40.
