The Panasonic microprocessor control system is secure, easy to use and comprehensive. Setpoint, alarm parameters and self-diagnostic
functions are accessed through a tamper-resistant keypad protocol. Control inputs are managed with convenient push buttons on a unitized,
sealed control overlay. The panel is door-mounted and angled for easy access.

condition; alarm ringback is factory set for 30 minutes,
adjustable in 10 minute increments from 10 to 60 minutes.
• Panasonic exclusive Ni-MH battery powers control memory

Status alert function uses predictive intelligence to determine if freezer is
operating within specications under existing environmental conditions.

chamber temperature. Display
mode changes when setpoint, alarm
parameters, programming and
