Introduction:
The LR-5 TempGuard control system was designed to provide many years of
reliable service. This control utilizes micro-controller technology to continuously
monitor the temperature in the refrigerator/freezer and to maintain the temperature
within the limits set by the user. The control settings are easily adjusted through the
LR5 TempGuard front panel and the control “remembers” the coldest and the
warmest temperatures achieved in operation.
