Additional information!
Manual: RS8DC
The installation of data communications must comply with the require-
ments described in literature sheet no. RC8AC
Supply
voltage
230 V +10/-15%, 50/60 Hz, 5 VA
Sensors
Pt 1000 ohm for refrigerant temperatures
Pt 1000 ohm or PTC (R25 = 1000 ohm) for air temperatures
Controller
sensor 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, operating buttons
Digital input
DI1
If a contact function is connected, ir can be used for alarm func-
tion, defrost start, night operation, start/stop of the regulation or
cleaning signal
If other EKC 514B units are connected, coordinated defrost can be
performed via cable connections
Digital
output DO1
May in conjunction with the digital input be used for coordinated
defrost via cable connections
230V input
0 V: regulation stopped. The compressor relay, the defrost relay
and the fan relay are cut out.
