system
The controller has no display or operating buttons on
front panel.
Operation takes place via a separate, connected dis-
play or via data communication
Display/
operation
It is possible to connect two displays with 0.1% reading
accuracy in the measuring range:
EKA 161, LED, three digits
EKA 162, LED, three digits, two operating buttons
If a contact function is connected, ir can be used for
door alarm, defrost start, night operation or start/stop
