To replace the Carrier® ChillerVu™'s battery
The Carrier® ChillerVu™'s 10-year Lithium CR123A battery retains the following data for a maximum of 720 hours
during power outages: time, control programs, editable properties, schedules, and trends.
To conserve battery life, you can set the driver to turn off battery backup after a specified number of days and
depend on the archive function to restore data when the power returns.
A low battery is indicated by the
Battery low
LED or a low battery alarm in the i-Vu® application. You can purchase
replacement batteries from any retailer that sells a CR-123A battery.
1
Verify that the Carrier® ChillerVu™'s power is on.

Using a small flathead screwdriver, pry up each side of the black battery clip until it is free and you can
remove it.

Remove the battery from the expander, making note of the battery's polarity.
4
Insert the new battery into the expander, matching the polarity of the battery you removed.

Push the black clip back onto the battery until you hear both sides click in place.

Download the Carrier® ChillerVu™.
To replace the fuse
