General system information
The Thermo E system is a special piglet nest heater and not a space heater since it warms
the animals through body contact.
The system should only be assembled and put into operation by qualified technicians and
only within the framework of the technical guidelines. MIK will assume no liability
whatsoever for damage that results from improper usage or operation.
Only use MIK TR-A and MIK TR-D regulators togther with the protection relay/contactor as
described in the following pages to ensure a safe functioning of the heating system. Only
Thermo E temperature sensors are to be connected directly to the TR-A and TR-D
regulators. All other heating panels must be connected via the protection relay/contactor.
Please refer to following switch/wiring diagrams.
The guarantee will become void if the system is used in combination with any third
party products.
The TR-A and TR-D regulators are to be used exclusively for operating MIK Thermo E
panels.
Protection class II is designated for the connection and the maximum power input is to be
taken into consideration.
TR-A and TR-D regulators are designed to be installed in protection boxes and
should only be connected, opened and repaired by qualified electricians. The
equipment is to be completely switched off before handling or opening the device!
Always keep the lid of the protective housing of the TR-A/TR-D regulators closed to prevent
the infiltration of moisture. Do not allow water to spray directly onto the housing when
cleaning.
The Thermo E electric panels can be cleaned using a high pressure cleaner (from an
appropriate distance!). Do not use chemicals to clean the Thermo E surfaces. This applies
especially to nitro-cellulose thinners and products which contain this or similar substances.
TR-A and TR-D regulators do not need servicing. The surface of the device can be cleaned
with a cloth.
The water used to fill the Thermo E 400/500/600x1200 must not have anti-freeze or
chemically similar active inhibitors (e.g. hydrazine, etc.) added to it. It must not contain any
quantities of chlorine, fluoride or any other additives which cause an aggressive reaction
with metals and seals.
Thermo E 400/500/600x1200 panels need to be filled up with water before the system is
operated. The temperature of the water used to fill the panels must not be less than 10°C.
The operation of non-filled panels is forbidden and failure to observe may lead to
irreparable damage to panels!
If you have any queries or further questions about the system, please do not hesitate to call
your MIK stockist or our customer service.

Thermo E with and without sensor
Thermo E panels are available in two designs – with and without temperature sensors.
Each heating circuit must always include one Thermo E with a temperature sensor to allow
use of the automatic temperature control function.
In general, all Thermo E panels without sensor need to be connected to the contactor, all
panels with sensor need to be connected to TR-A or TR-D directly.
1. Multiple nest regulation/max. number of connected Thermo E
When using the TR-A regulator, 30 Thermo E 400x600 or 10 Thermo E 400/500/600x1200
panels can be connected to one circuit, one of which must have a sensor. This means that
a total of 60 Thermo E 400x600 (2 circuits/contactor x 30 panels) or 20 Thermo E
400/500/600x1200 panels (2 circuits/contactor x 10 panels) can be regulated with each
TR-A.
When using the TR-D regulator, max. 120 panels Thermo E 400x600 (2 circuits/TR-D x 2
circuits/contactor x 30 panels) or 40 Thermo E 400/500/600x1200 (2 circuits/TR- D x 2
circuits/contactor x 10 panels) can be operated via two circuits each of the TR-D and the
contactor. Again, at least one Thermo E panel with sensor per circuit needs to be
connected to the regulation unit. All sensor cables are always directly connected to the
TR-A or TR-D (top terminals) regulators. All Thermo E panels without sensor cables are
always connected to the contactor.
2. Single nest regulation
If single nest regulation is required, a control circuit must be provided for each warming
nest and the appropriate number of regulators need to be installed. A single nest can be
controlled with the TR-A single circuit regulator, and two single nests can be controlled
individually using the TR-D double circuit regulator.
Installing Thermo E
MIK Thermo E heating panels are integrated in the MIK floor system flush with one
another and seamlessly affixed to the support beams (5mm thick). The supplied hook
strips are used to do this with the models Thermo E 400/500/600x1200mm. This means
that all Thermo E panels are combinable row-wise with all the MIK plastic panels. They are
laid in the same manner as all MIK panels, with the exception that the panels cannot be
cut to shape. They can be post-installed in an existing floor system whenever required.
It is fundamentally possible to combine heating panels of different sizes. Due to their
varying performance and switching characteristics (response behaviour when heating and
cooling down), they do however have to be operated in separate heating circuits with their
own sensor panel of the same model. It is not permitted to connect different Thermo E
models to the same heating circuit!
Thermo E panels can be laid adjacent to one another or in series in a row. A gap of 10 cm
should be left along the pen dividing wall to ensure a hygienic surface and optimum usage.

Farrowing:
MIK recommends laying three Thermo E 400x600 heating panels or respectively one
Thermo E 400/500/600x1200 heating panel in each pen so that smaller or weaker animals
will still have sufficient space on the heating surface. The nest is positioned outside of the
sow standing area.
Nursery:
20-25% of the total pen floor area in the nursery should be foreseen as a heated area. The
Thermo E panels can be laid in rows, or in an L or U shape with all-round perforation. An
adequate gap must be left between the panels and pen dividing walls or feed and water
troughs.
Using the hook strips with the Thermo E 400/500/600x1200
The hook strips are supplied together with the heating panel. We recommend using only
the hook strips when laying the MIK Thermo E heating panels to ensure that they are
securely fixed into place. The hook strips are installed when laying the panels. They are
mounted on the beams in the panel framework using the toothed bar at the position where
the Thermo E is to be laid. The design of the hook strips automatically determines the
exact position of the heating panel with the aid of its centring tabs. Three hook strips are
intended to be installed on each side. Two different hook strips are used with the MIK floor
system. They are laid in the panel framework so that no gaps are left. Three hook strips
have a total length of 1.2 m. A gap of approx. 10 mm is left between two heating panels
when laying two or more Thermo E panels one after the other. This is intentional and is
designed for expansion and cleaning purposes. The width of this gap is compliant with
German animal welfare and livestock farming regulations (TierSchNutztV).

Thermo E heating panels are supplied with and without temperature sensors. Thermo E
panels without a sensor are only fitted with one power cable on the underside. Thermo E
panels with sensor are fitted with an additional sensor cable. The power cable is the
thicker of the two cables and leads out of the round aperture at the edge (Thermo E
400x600) or out of the tube thread (Thermo E 400/500/600x1200). The thinner sensor
cable leads out of the panel body through a separate aperture.
The cable is laid and fastened into place underneath the plastic framework. The cables
can be affixed to the beams using cable ties (see Fig. 14). Protective tubing can also be
used for laying the cables. These should be sealed at the ends to prevent the infiltration of
rodents and accumulation of dirt.

The cable must also be laid in protective tubing along the wall leading out of the room to
keep them out of reach of the animals.
Project-specific extensions to sensor and load cables must comply with protection class IP
65. Thermo E 400/500/600x1200 panels are equipped as standard with appropriate splice
connectors for this purpose. Heat shrink tubing, which offers extra protection at the joints,
is also supplied with these heating panels. The procedure is demonstrated below using the
example of extending the sensor cable of a Thermo E 500x1200 panel:
1) Strip the strands of the extension cable to fit the
splice connectors and pull the heat shrink tubing
over the panel connection cable.
3) Now heat shrink-wrap the splice connectors
onto the cables on both sides using a hot-air
blower.
2) Firmly squeeze the strands of the extension
cable into the extension end of the splice
connectors using pliers.
4) Finally, slide the heat shrink tubing over the
joint and use the hot-air blower to heat shrinkwrap the cable starting in the middle and working
your way to the ends – finished!

According to the European standard EN 60335-2-71, mains connection cables are
not allowed to be lighter than conventional cables with polychloroprene sheathing.
Usage of the cable type H05RN-F ensures compliance with this standard.
In practice, so-called H05VV5-F, H03VV-F & LiYY-ÖW "Ölflex" cables have also
proved effective for extending (sensor) cables. The cross-section of the extension
cables should not be less than that of the fitted connection cables (ref:. "Technical
details" on page 3).
Sensor and power cables must always be extended using separate cables!
This means that the current and sensor conductors must not be combined in a multiconductor cable.
TR-A assembly / installation
General:
The assembly may only be carried out by a licenced electrician!
Sensor connection: The temperature sensor is connected to two terminals.
The polarity does not have to be taken into account.
The maximum permitted cable length is 100 m at 1.5 mm2 Cu.
Assembly
- The device is mounted in the terminal box.

TR-D operation and display
Two independent control circuits are integrated in the TR-D, each of which records
the actual temperature with a separate sensor and then adjusts the setpoint
temperature in line with the settings.
Function
The device can be operated in two different modes depending upon the task in hand.
"Normal mode" is for continuously controlling a constant setpoint temperature,
whereas "Heating curve mode" is used to adjust the setpoint temperature in line with
a growth cycle.
Depending upon the operating mode, the setpoint values are either set directly using
the control dial or determined by the programmed heating curve.
The actual temperatures are indicated for each control circuit in turn on a three-line
display for about 8 seconds. The LED of the respective control circuit flashes when
its temperature is displayed.
The switch status of the relay is indicated by a red LED on the device (LED on =
relay is switched on). Which operating mode is currently selected is also shown on
the display.
"Normal mode" operation
In "Normal mode", the device functions as a two-position controller with a variable
setpoint value. The setpoint value is set using the respective control dial and does
not have a time limit. The required values are set on a notional scale between 20°C
and 50°C. The current setpoint value is shown on the display while it is being set.
The actual value is shown again after about 3 seconds. The setpoint value can also

be displayed by briefly pressing the CHx button (CH1 for control circuit 1, CH2 for
control circuit 2).
The green LED flashes when a setpoint value is being displayed! The corresponding
red LED lights up constantly at the same time to indicate the respective control circuit
to which the value belongs.
The respective control circuit is switched off by turning the control dial to the "OFF"
position. "OFF" is then shown on the display after a short time instead of the actual
temperature.
A control circuit can only be fully deactivated in "Normal mode".
The control circuits are switched from "Normal mode" to "Heating curve mode" by
pressing the CHx button for approx. 5 seconds. The device is reverted to "Normal
mode" in the same way.
"Heating curve mode" operation
In "Heating curve mode", the setpoint value (beginning with a start
temperature, e.g. 38°C) is run down over a predefined period of
time to an end temperature (e.g. 30°C). This is done by
programming the parameters "tS.." (start temperature), "tE.."
(end temperature) and "hr.." (duration in hours per 1°C reduction
in the setpoint value) in the device. When the device is switched
from "Normal mode" to "Heating curve mode", the timer is stopped
and the parameter "tE.." stipulates the end temperature (this
must be checked!). A decimal point now lights up continuously in
the bottom right corner of the display. This signalises that the timer
has stopped. A quick press (approx. 1s) of the CHx button briefly
displays the setpoint value – "tS.." – and the timer is started. The start
temperature is determined by the parameter "tS.." and the decimal
point flashes in the segment on the right. The operation is stopped
again with another press of the CHx button. This resets the timer and the setpoint
value – this is displayed briefly – is set to "tE..". The decimal point lights up again
continuously.
The current setpoint value for a heating curve can be changed while the programme
is running. The new setpoint temperature is simply selected for the appropriate
heating circuit using the control dial.
The previously configured setpoint value is shown on the display until the control dial
setting corresponds to this value.
The setpoint value can be changed if these two values match. Once the required
value has been set, it is automatically taken over within a few seconds and becomes
the valid setting. The actual temperature is displayed again. The timer is not
interrupted as a result. When the heating curve has been completed, the manual
correction of the setpoint value is deleted again and the saved values apply without
any restriction.

To check the current setpoint value during an active heating curve, it can be shown
on the display by briefly (< 1s) pressing the CHx button. After a few seconds the
display reverts back to an actual value.
The green LED flashes when a setpoint value is being displayed! The red LED for the
respectively selected output lights up continuously. This indicates that a setpoint
value is being displayed and which one it is.
Once the heating curve has started, the setting "tS.." applies as the setpoint value.
The parameter "hr.." now determines after how many hours (setting 1-99) the
setpoint value is to be reduced by 1K. The duration of the heating curve is calculated
from the difference in temperature between "tS.." and "tE.." and the interval "hr..".
Here is an example:
"tS.." = 32°C, "tE.." = 25°C, "hr.." = 24 (h/K)
32°C-25°C = 7K * 24h/K = 168h (7 days). The setpoint temperature "tE.." is attained
after a runtime of 168 hours and the heating curve has then been completed. The
process is controlled without any time limit according to the value "tE.." (25°C).
Programming the heating curve
The parameters for the heating curve are programmed in a submenu. This is opened
by pressing the CH1 and CH2 buttons simultaneously for approx. 5 seconds. In the
submenu, the control dial for the 2nd control circuit can be used to "scroll" through
the various parameters. A press on CH2 shows the parameter value. To change this,
slowly turn the control dial around the notional scale range. If the saved and set
values match, the set value is "captured" and can now be changed. The required
setting is saved by pressing CH2 once more and the parameter list is displayed
again. This allows the required values to be set one after the other. The submenu is
closed by selecting "End" and pressing CH2 and the device switches to the previous
operating mode.
An active heating curve cannot be changed and is not interrupted by opening the
submenu.
The illustration below shows the submenu and the values "behind" the parameters.
You always switch between the parameter and the value by pressing the CH2 button.
The values are set using the control dial for the 2nd control circuit.

Note that the programmed start value must always be higher than the end value.
The time cannot be started if the values have not been programmed correctly ( tS..
<= tE..). The process continues to be controlled according to the value tE...
The programming is aborted in the event of a lengthy pause (approx. 3 minutes).
Unconfirmed values are rejected.
Functionality after putting into operation or restoration of power
The "Normal" and "Heating curve" operating modes are saved. After power has been
restored, the most recent operating mode is called up and applied as follows:
"Normal mode":
The process is controlled according to the configured
setpoint value (control dial setting); this also includes the
"OFF" setting!
"Heating curve mode": The timer is stopped; the process is controlled according to
the setpoint value for the parameter "tE..".
Optical display
A red LED for each output indicates the switch status of the relays. A green LED
shows the operational readiness of the device. A 3-line display is integrated in the
device for showing the setpoint and actual temperatures, help texts for programming,
and status reports. The respective LED flashes briefly to allow the displayed
temperature to be matched with the corresponding heating circuit. The displayed
actual values (sensor) are shown alternately for approx. 8 seconds.
Sensor monitoring
Both sensor inputs are monitored for short circuits or breaks. If the device detects a
defective sensor, the corresponding output is deactivated. "Err" is then shown on the
display instead of the actual value. The limits for troubleshooting are temperatures >
80°C and < -20°C.
Output
The device has one relay output (N/O contact) per channel. This is lead through to
the respective terminal with applied voltage (with L). See "Technical details" for the
maximum load. The device does not have an internal fuse. The operator must ensure
that it is properly protected.
Supply voltage
The device is designed to be operated with 230V/50Hz AC voltage. It does not have
an ON/OFF power switch. It is designed to be connected only to fixed installation
wiring.

Setting the temperature
Fluctuations in the temperature of the Thermo E panel are caused by the prone
positions adopted by the piglets. As the temperature needs of the piglets cannot be
determined by the age of the animals, their prone positions must be observed and
the temperatures set accordingly (Fig. 18).

Fig. 18: Prone positions of piglets and heating requirements at different temperatures
At birth, the surface temperature of the Thermo W panel should be set at between
approx. 38°C - 41°C. The piglets should lie either on their sides or their fronts.
During the first one or two days, an infra red heating element can be additionally
installed over the piglet nest as the animals need a great deal of warmth at this time.
