Note: The Variō Pro controller will not allow the user to select a maximum chamber temp greater than
or equal to the high temperature alarm setpoint. As a result, it may be necessary to adjust the high

for further instruction.
6. To adjust the chamber temperature deadband, use the
desired value and press ENTER to save. Note that the chamber deadband also
defines the minimum (coldest) allowable chamber temperature.
Note: The Variō Pro controller will not allow the user to select a maximum chamber temp
chamber deadband combination that results in a minimum chamber temp less than or equal to the
low temperature setpoint. As a result, it may be necessary to adjust the low temp alarm prior to
changing the chamber deadband.

initial cooling cycle, it will be necessary to disable the alarm. Use the
to select DISABLED and press ENTER to save. Press ESC repeatedly to return to
