Functional Description
Display & Sensors
All temperature values can be displayed in °C or °F
with a resolution of 0,1K (0,2°F), selectable by P21.
TF201, TF 202 (PTC) as well as TF501 (Pt1000)
sensors can be used, but note that this results in
different temperature ranges. Sensor 2 (Evap. Limit
Sensor) can be disabled.
Temperature Control
The controller compares the actual room tempe-
rature (P01) with the control setpoint (P03) and
activates the cooling relay which is able to switch
solenoid valves or compressors. The switching
hysteresis (P09) prevents the system from short
cycling. An idle time (P11) prevents a compressor
from switching ON again immediately.
Setpoint range
With P07/P08 you can limit the setpoint range to
prevent the end-user from entering critical values.
Switching mode of cooling relay K1
The switching behavior of the cooling relay
(= cooling mode) is defined by parameter P10.
2. Setpoint / day-night-shift (1380-2 only)
Toeconomize energy, e.g. atnight, theunitcan work
withasecondsetpoint(P04),whichcan beactivated
by the internal time-switch (P05/P06).
Emergency Mode of Temperature Control
If the control sensor fails, the unit starts an emer-
gency mode. The refrigeration relay switches on in
a percentage rate of a total period of 30 minutes,
presetbyP39.E.g.:selecting40%means12minutes
on, 18 minutes off.

Temperature alarm
A temperature alarm is indicated by:
• A LED at the front
• An internal beeper
(TAR 1370H-2/TARN only)
• An alarm relay
(TARN-Types: Only if the fan relay is not
in use).
If the temperature measured by the control
sensor exceeds the range set by P32/P33,
P18 shows the remaining time until an
alarm occurs. After the delay timer P31 is
run down, the alarm relay will be activated.
P32 is an alar m offset located relative to the
currentsetpointP03resp.P04,soifthesetpoint
is shifted, the offset remains constant.
If the alarm mode P30 is set to '4', the alarm
relay can be reset while the temperature is
located withinthealarmrange.Thisis usable
e.g. to switch an external signal horn. If the
temperature comes back to the working ran-
ge, the relay will be reset automatically.
Alarm relay / Beeper Operation Modes
Parameter P30 fixes the alarm relay mode:
0= Alarm relay active ON
1= Alarm relay active OFF
2 = like 0, but internal beeper off
(TARN only)
3 = like 1, but internal beeper off
(TARN only)
4= Alarm relay can be reset while
temperature is located within the alarm
range. Can be used e.g. to switch an
external horn.
5= Continuous ON of alarm relay if
control setpoint 2 is activated
(TARN 1380-2 only). Alarm messages
will be forwarded by alarm-LED only.
Function to switch light by time control.
5= The alarm relay output works as fan
relay (TARN types only).
Alarm Beeper (1370H-2 and TARN only)
These types contain an integrated beeper
(can be disabled by P30), which is activated
with the alarm output. The beeper can be
reset by any keypress.
Defrost
The unit is equipped with a defrost relay.
There is no need for external interlocking the
defrost output with the cooling output since
the temperature controller is disabled while
defrost.ForinformationthereisP15 showing
the remaining time of the existing defrost
event until termination by time.
Defrost by Real time clock (1380-2 only)
This type contains a real time clock with 6
settabletimes,whichallowsyoutoinitiatefour
defrost events a day and to switch to 'night'-
setpoint. The timer has a power backup for
about 10 days in case of power failure. The
clock time can be set by parameters P34
and P35 (minutes).
Becausethedisplayhasonlythreedigits, the
time value comes in the following format:
The defrost times are set by P24 - P27 in
10 minute increments in a 24 hour (military)
format. Example: 13.20 = 01:20 p.m.
Switch times can be de-activated by setting
to 'oFF'. The second setpoint depends on
P05/P06.
Defrost Modes of the 1380-2 types
P23 determines the defrost mode, which
works independent from the control relay.
1 = Heater or Airflow Defrost
- Defrost relay active ON
(= defrost heater ON)
- Cooling relay switches OFF.
2 = Hot Gas Defrost
- Defrost relay act. ON
(= bypass valve open)
- Cooling relay keeps the solenoid
valve open
3 = Heater or Free Airflow Defrost + (AZV)
Relay characteristic like = 1.
Addtional generated defrost events.
4 = Hot Gas Defrost + (AZV)
Relay characteristic like = 2.
Addtional generated defrost events.
3rd Position=
minutes x 10
1st. and 2nd
Position = hours
Defrost time doubling (AZV, 1380-2 only)
This is a simple function to double the
quantity of the potential defrost events (4
—> 8). The unit generates new defrost
times automatically by adding 12 hours to
existing times.
Example:
If a defrost cycle is fixed at 14:30, an
additional cycle starts at 2:30am without
entering this time.
Defrost by Cyclic Timer (1370(H)-2 only)
P24 determines the interval time up to the
next defrost event, P28 fixes the defrost
duration. The cyclic timer starts with power-
up of the TAR, the first (automatic) defrost
event is possible first after the end of the
first interval time.
Defrost modes of the types 1370-2,
1370H-2)
P23 fixes the defrost mode.
1 = Heater/Airflow Defrost by Cyclic Timer
- Defrost relay act. ON
(= defrost heater ON)
- Cooling relay switches OFF.
2 = Hot Gas Defrost by Cyclic Timer
- Defrost relay act. ON
(= bypass valve open)
- Cooling relay keeps the solenoid
valve open
3 = Heater/Airflow Defrost by
Machine Runtime
Like 1, but depending on the added
ON times of the cooling relay.
4 = Hot Gas Defrost by Machine Runtime
Like 2, but depending on the added
ON times of the cooling relay.
Manual Defrost
• At parameter P37 by key "" or
• While the actual temperature can be read
on the display, by holding key "" key for
more than 2 sec.
Defrost Termination
• Thermal termination.
Defrosting will be terminated whenever
the evaporator sensor temperature (P02)
exceeds the temperature limit set with
parameter P22.
• Termination by (safety) time.
The time set with parameter P28 is the
maximum time a defrost cycle can last
before it is terminated automatically.
• Manual termination.
With parameter P37 you can terminate a
defrost cycle by pressing "" key.
or
While the actual temperature (P01) can
be read, a defrost event can be terminated
by holding "" key for more than 2
seconds.
• If the defrost limit sensor is interrupted,
the defrost event will be stopped immedi-
ately.
After the defrost event is terminated, a drain
time P29 delays the begin of the cooling
function. P16 shows the remaining time until
cooling starts again.
(DH) Display Hold-Funktion
The DH function can be initiated by P38.
It holds the Actual Value Display while a
defrost event. During defrost the display
showsthelast measuredactual value before
defrost start. After defrost termination: If the
actual value is higher than the stored display
value, the display keep unaltered for further
15 minutes max. If the actual value falls 2K
below the stored display value, the display
shows the actual value again.
Evaporator Fan Control
FanoperationmodescanbeselectedbyP13.
AtTARN-typesthealarmrelayoutputcanbe
selected (by P30) as fan relay alternatively.
1 = Fan runs if cooling output is active.
With defrost termination the fan output
is OFF until the Fan Delay Time (P14)
is run down.
2 = Fan runs continously, except during
defrost and Fan Delay Time (P14) after
defrost.
Fan trailing: The fan stops if the temp-
eratureattheevaporatorsensorexceeds
P12.
3 = Fan runs if the compressor output is on,
and during defrost.
The temporal fan delay must be set
to "0".
Forall3fanoperationmodesatthe
sametimethereisathermostaticfan
delayactive,becausethefanstarts
only if the evaporator temperature falls
3K below P12. If this function is not desi-
red, P12 can be set to its upper threshold
to make it inefficient.
After the end of a defrost cycle
A temporal fan-ON delay is active after a
defrost event (P14). While drain time (P29)
the fan remains stopped.
(P17) informs about the remaining time until
the fan starts again.
Practical conditions
If you want to realize a thermostatic delay,
select fan mode 2and adjust setpoint P12.
If you want to realize a thermostatic delay
and airflow defrost, please realize a parallel
connection of fan relay and defrost relay.
