Sensors
Pt 1000 ohm for refrigerant temperatures
Pt 1000 ohm or PTC (R25 = 1000 ohm) for air tempera-
tures
Controller sen-
sor system
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, two operating buttons
1 digital input
If a contact function is connected, ir can be used for
door alarm, defrost start, night operation or start/stop of
the regulation
If other EKC 414 units are connected, coordinated de
-
frost 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 the light relay are cut out.
230 V a.c.: regulation
(The function can be opted out).
