In the following example matrix, the EMS controller will start to cool by the saving restart period
before the ready period (2), run in the ready mode for 30 minutes, and then switch to the
saving
mode
(assuming no delay to saving
ds
parameter is in operation).
For more information about the parameters used:

Ready mode
EMS controllers run in the
ready mode
when outlets are open.
In the
ready mode
, the product is at the correct serving temperature and the cooler lights are on.
EMS controllers ensure that the product is at the correct serving temperature by keeping the
product temperature within the range defined by set point (
S P
) parameter and the differential (
dI F
)
parameter.
The EMS controller runs the compressor until the set point (
S P
) temperature is reached. The com-
pressor is then stopped until the measured temperature reaches the set point (
S P
) plus differential
(
dI F
) temperature.
During the
ready mode
, EMS controllers display appliance sensor temperature 3.0, for example or the
word
US E
as defined by display (
dI S
) parameter.
If the EMS controller displays the appliance sensor temperature, the display stability (
d2
) parameter
can dampen the rate of change of the displayed temperature.
For example, to filter short fluctuations in the air temperature due to the door opening, which has no
affect on the product temperature.
