4 How it works
EN
4 How it works
The RITTAL Thermoelectric Cooler uses the Peltier
effect for cooling/heating. This effect is based on
the principle that an electric direct-current flowing
through a circuit consisting of two different metals
causes the cooling of one contact point and the
heating of the other contact point. An appropriate
layout for the cooling/heating production is desig-
nated as Peltier element.
When the Peltier effect is used for enclosure climate
control, an air flow is fed over the upper and lower
connection point. The heat energy is released or
accepted from the air flow to the Peltier element.
The air flow that releases the heat energy to the
element is introduced as cooling air flow in the
enclosure or the operating housing.
After the
heating of the cooling air flow by the active in-
stalled equipment
, it is returned to the climate control
unit and fed for renewed cooling over the “cold” side
of the Peltier element. This produces an air circulati-
on that causes the cooling of the enclosure or the
operating housing.
The air flow that accepts the heat energy from the
“warm” side of the Peltier element is released as
warm air flow to the external air circuit of the climate
control unit. This means the heat produced by the
components in the enclosure is dissipated to the
ambient air surrounding the climate control unit.
By reversing the polarity with the controller, depen-
ding on the unit's setpoints, operation is switched
to heating. This will reverse the process described
above.

RITTAL Thermoelectric Cooler assembly and operating instructions 7
EN
5 Control
The RITTAL Thermoelectric Cooler controls the cool-
ing/heating capacity of the Peltier elements and the
air throughput of the integrated fans so that the re-
quired internal temperature of the enclosure or the
operating housing is set with high accuracy. For this
purpose, the device permanently monitors the air
entry temperature at the warm air entry (internal cir-
culation). If this temperature exceeds or falls below
a parameterised temperature value (factory setting:
cooling 35°C/heating 5°C), the device starts cooling/
heating operation. To do this, the trigger voltages of
the Peltier elements and fans are corrected by a PID
control so that the cooling/heating capacity required
for the cooling/heating is always available and the
cooling/heating operation is provided with the least
possible power. The redundant fans in the external
air circuit of the RITTAL Thermoelectric Cooler have
variable air delivery rates (and consequently variable
speeds) appropriate for the required cooling/heating
capacity. If only limited or indeed no cooling/heating
capacity is required, this control behaviour can lead
to a temporary inactivity of the fans in the external air
circuit. This does not constitute a malfunction of the
device, but rather an extreme power-saving opera-
ting state that also increases the service life of the
used fans.
Note:
The fan speed in the external air circuit of
the climate control unit is matched to the
current cooling/heating capacity require-
ment.
Consequently, a stoppage of the fans –
interrupted by periodic, short-term fan
starts – is not a malfunction of the device,
but rather represents an extreme power-
saving operating state!

RITTAL Thermoelectric Cooler assembly and operating instructions 9
EN
7 Device mounting
The following principles must be observed for deter-
mining the mounting position on the enclosure or
operating housing:
The RITTAL Thermoelectric Cooler is mounted as
external or full internal mounting.
The supplied drilling template must be used to fasten
the climate control unit on the enclosure or the ope-
rating housing.
The drilling template provides dimension lines for the
various installation options of the climate control unit.
Identify appropriate lines and dimensions on the dril-
ling template for the required mounting type (exter-
nal or full internal mounting) using figures 6 and 7.
Drill the required holes for fastening the climate con-
trol unit and then cut the required cut-out, including
the line width, in accordance with the drilling temp-
late.
The direct incidence of cold/warm air on
temperature-sensitive components must be
avoided!
Components with integrated fans deter-
mine the air routing in the enclosure or
operating housing.
The mounting position of the climate control
unit must be chosen so that the air flow
supports the cooling/heating of these com-
ponents.
A free space of at least 100 mm is required
in front of the air inlet and outlet openings
of the climate control unit in the internal and
external circuit.
The climate control unit must be positioned
on the enclosure so that the condensate
discharge opening is located at the lowest
point of the climate control unit.
Risk of injury!
Wear protective gear (safety glasses,
protective gloves) when cutting the
mounting cut-out and drilling the fasten-
ing holes.
Carefully deburr all drilled holes and
cut-outs to prevent injuries caused by
sharp edges.

7.1 External mounting
When the climate control unit is mounted as external-
ly-mounted variant, the supplied self-adhesive seal-
ing tape must be fastened on the device rear wall of
the climate control unit so that no gaps result at the
joint edges. Secure the climate control unit using the
supplied washers and cheese-head screws.

Fig. 10: External and internal mounting
Fig. 11: Permissible mounting positions
7.2 Internal mounting
For the full internal mounting of the climate control
unit, the louvred grille must be carefully removed
from the device. The self-adhesive sealing tape
supplied must be placed on the front of the climate
control unit (the device face from which the louvred
grille has been removed) so that no gaps result at the
joints. Secure the climate control unit using the sup-
plied washers and cheese-head screws. To com-
plete the mounting, the louvred grille must be re-
attached.

EN
8 Filter mounting
The RITTAL Thermoelectric Cooler can be equipped
with a device filter (supplied).
An appropriate filter unit is recommended when the
climate control unit is used in ambient air subject to
dust.
When a filter is installed, the lower louvred grille in
the air inlet of the climate control unit must be remo-
ved. To do this, raise the louvred grille with a light tug
at the marked position (see Figure 14) and withdraw
it at the front. Then place the filter mat in the filter hol-
der of the device. The colour-marked side of the filter
mat must face the device. Then re-mount the louvred
grille and snap it into position by applying light pres-
sure.
Fig. 14: Removable louvred grille
9 Mounting of the
condensate discharge
The RITTAL Thermoelectric Cooler is equipped with
a condensate discharge.
Fig. 15: Condensate discharge
The controlled condensate discharge requires a
condensate discharge hose be connected to the cli-
mate control unit’s condensate discharge supports.
The condensate hose is available as accessory.
The installation of the condensate hose requires
that it
– is laid with a gradient (no siphon formation),
– does not have any kinks,
– must not have a reduced cross-section if
extended.
Note:
When a filter unit is used, it must be cleaned
regularly or, if necessary, replaced.
Risk of injury!
The operation of the climate control unit
without controlled condensate dis-
charge can cause liquid to accumulate
below the device.

14 RITTAL Thermoelectric Cooler assembly and operating instructions
13 Commissioning
EN
13 Commissioning
The RITTAL Thermoelectric Cooler is operational
immediately after connection of the power supply.
If the factory setting is unchanged, the temperature
control of the enclosure or operating housing uses
the following parameters:
Set enclosure interior temperature: +35°C
Start temperature for cooling operation: +35°C
High temperature alarm message: +45°C
Start temperature for heating operation: +5°C
Low temperature alarm message: –5°C
Under normal operating conditions, device operati-
on with unchanged factory setting should ensure a
problem-free enclosure climate control. If it would
appear to be useful to change the predefined para-
meters for special climate control requirements, this
can be realised with programming software.
The RTC PC software can be found on the CD-ROM
supplied.
Optional:
Master-slave operation (available on request).
14 Status and function displays
The RITTAL Thermoelectric Cooler is equipped with

16 Maintenance and cleaning
16.1 Maintenance
The RITTAL Thermoelectric Cooler is low-mainte-
nance.
16.2 Cleaning
If the RITTAL Thermoelectric Cooler is used in ambi-
ent air subject to dust, dust can accumulate in the
area of the air inlet and outlet openings and on the
heat transferring surfaces of the Peltier element. This
can cause a reduction of the air flow in the device
and thus a gradually reducing cooling/heating capa-
city.
To remove the dust, withdraw the louvred grille at the
device front. Blow compressed air through the air in-
let and outlet openings of the climate control unit.
If the Peltier climate control unit is equipped with a
device filter, it must be cleaned or replaced regular-
ly. The filter mat can be cleaned by washing, dusting
or blowing with compressed air. The high-quality
filter material used for the mat means the cleaning
does not impair the filter-technical properties and the
form stability. The fire class remains unchanged!
Danger!
Prior to any cleaning or maintenance
work, the power to the climate control
unit must be disconnected!
Note:
When the filter is replaced, use only filter
materials approved for the RITTAL Thermo-
electric Cooler.
The dust collecting efficiency and dust
storage capacity of the chosen filter equip-
ment is matched to the rated flow speed of
the climate control unit in the external air
circuit and so guarantees an excellent dust
filtering for a high useful cooling output.
