All setpoints and parameter settings are retained permanently in a special nonvolatile computer chip memory,
preventing their loss due to a power outage. This nonvolatile memory chip allows the unit to be programmed
before installation. No battery powered backup is required.
Built in test circuits are provided to test each individual relay output wiring and to allow for quick field
service isolation of faulty probe, circuit cards, pumps, or solenoids for ease of troubleshooting.
A display for temperature is also provided. The range is 32° F to 158° F [0° C to 68° C]. The display can be
either fahrenheit or centigrade. This reading also provides the basis for temperature compensation which is
performed in all modes.
