AKV-ON denition
When the ON input is cut out refrigeration is
stopped.
Here you dene how the fan relay and the
alarm function are to act:
1 = Fan relay = ON, alarm monitoring active
2 = Fan relay = OFF, alarm monitoring active
3 = Fan relay = OFF, no alarm monitoring
4 = Fan relay = ON, no alarm monitoring
5 to 8 = as 1 to 4, but without connection to
terminal 40-41.

Sensors
Pt 1000 ohm for refrigerant temperatures
Pt 1000 ohm or PTC (R25 = 1000 ohm) for air
temperatures

Measuring range -60 to +50°C
Accuracy
±0.5°C
for sensor temperature =
-35 to +50°C
Display/ opera-
tion
The controller has no display or operating buttons on
front panel.
Operation takes place via a separate, connected display
or via data communication
It is possible to connect two displays with 0.1% reading
accuracy in the measuring range:
EKA 163, LED, three digits
EKA 164, LED, three digits, + operating buttons
1 digital input
If a contact function is connected, ir can be used for
door alarm, defrost start, night operation, door function
or start/stop of the regulation
If other EKC 414C1 units are connected, coordinated
defrost can be performed via cable connections
1 digital
output
May in conjunction with the digital input be used for
coordinated defrost via cable connections
230 V input
0 V: regulation stopped. The compressor relay, the de-
frost relay, the fan relay and rail heat relay are cut out.
230 V a.c.: regulation
Real time clock
For start of defrost. Can be mounted if data communi-
cation not is used.
