Danfoss EKA 153 Data sheet

Data Sheet

Thermometer

Accessory

Type EKA 153
For monitoring with 3 temperature sensors

The EKA 153 is a thermometer used for
registering up to three temperatures in
connection with Refrigeration Appliance
Controls. The temperatures can be read from
the display and sent to a central system unit via
data communication.

Alarm limits for high and low temperatures can
be adjusted. If the alarm setting is activated,
the LED lights will ash and an alarm signal will
be sent to the system unit via data
communication.

Design, tting and operation are the same as
controllers in the Danfoss EKC 202 series.
