ems controllers stop the evaporator when the cooler door is opened.
To prevent excessive condensation on the evaporator in environments where warm, and presumed humid air is present,
the controller runs the evaporator fan continuously if the temperature exceeds the fan set point (
FS P
) temperature. ems
controllers run the evaporator fan, even if the cooler door is opened, and continues to run the evaporator fan until reaching
the set point (
S P
) temperature.

lights management
In the saving mode, the cooler lights are usually off.
For marketing purposes, light delay (
L d
) can keep the cooler lights on for a short period after the ems controller switches to
the
saving mode
.
Marketing mode (
Ar
) can keep the lights on for the duration of the
saving mode
.

statistics
ems controllers start gathering statistics when first powered up.
Statistics provide information on the following:
l
temperature: lowest, highest, and average temperature measured on the appliance sensor.
l
activity: average number of motion counts and door openings.
l
compressor: average number of compressor cycles and total compressor runtime.
l
operation: settings of the activity frequency (
AF
) parameter and the saving temperature
disable (
PEr
) parameter.
l
Note:
l
A full reset clears all the gathered statistics.
l
Not all controllers allow statistics to be viewed - the ems25+ is teach enabled and therefore does not display statistics.

alarms
For alarm conditions, the ems controller displays the appropriate alarm code and, optionally, sounds an alarm buzzer.
Buzzer enable (
b0
) defines whether to sound a warning buzzer for alarm conditions.
