TM-201A multi-functional electronic thermometer, - 1 - MNU51203
TM-201A multi-functional electronic thermometer
The TM-201A multi-functional electronic thermometer can be used in all
installations where one or two temperature values need to be measured with
a subsequent relay closing or opening action. The thermometer is equipped
with warning (optical and acoustic) indication. It can be typically used
as a protective thermometer, bistable thermostat or difference thermostat.
Figure 1: Front view
1. Thermometer installation
Install the thermometer in such a way as to make it well visible to the user. Do not install it in places where it may
be exposed to intensive radiant heat. The thermometer is designed for wall-mounted indoor installation. It can be mounted
directly into a common device installation box or on plaster. The bottom part of the housing is always used for this purpose.
1. Remove the top part of the thermometer from the frame (by pushing a screwdriver into the gap between
the display and frame at the T2 indicator).
2. Release the bottom housing by pressing the four latches in the corners (figure 2).
3. First, mount the bottom housing and then snap the display frame into it.
4. Connect the supply cables of the sensors to the T1 and T2 terminals. Always tighten the terminals with
the terminal boards removed. Remove the terminal boards by pulling them towards yourself.
Both the temperature sensors are the same and they can be connected with either polarity. If just one sensor
is sufficient for the selected function of the thermometer, it should always be connected to the T1 terminals.
5. The contacts of the controlled device should be connected to the OUT terminals. The load capacity of the output
is 1 A/250 V and it has safety isolation characteristics. For higher loads use an auxiliary relay or contactor.
6. Connect the 12 V / 50 mA power supply to the + - terminals (observe the correct polarity). As the power supply
unit you can use:
a) LT-089.06 Jablotron.
b) DE06-12 Jablotron.
7. Switch on the power supply.
8. Use the UPŸand DOWNźcontrol keys to set the operational mode of the thermostat and the required
parameters
(see par. 4, Mode selection, Parameter setting).
9. You can reduce the illumination intensity of the display by connecting the LOW INTENSITY jumper
on the thermometer board.
10. Reinsert the top part of the thermometer into the frame.
Figure 2: Bottom housing Figure 3: Description of the terminals and boards
2. Installation of the sensors
Install the CP-201T temperature sensors (not included in the delivery) in the place to be measured (e.g. accumulation tank,
hot water reservoir etc.). Always ensure sufficient thermal contact (we recommend you to use a commonly available heat-
conductive paste). If no pockets are available, attach the sensors to the pipeline using tying tapes with sufficient strength
and insulate the sensors to prevent the ambient temperature from biasing the measurement (you are not recommended

TM-201A multi-functional electronic thermometer, - 2 - MNU51203
to use thin cable ties – they get loose with increasing temperatures and the sensor loses contact with the pipe; using metallic
tapes or collars is preferred).
Caution - the insulation of the supply cables of the sensors is resistant to a max. of 105 °C. The supply cables of the
sensors can be extended with the use of a common cable with copper conductors with a cross-section of at least 0.35 mm2
(the total length of the supply cable of a sensor should not exceed 30m).
3. Front panel indicators
Figure 4: display description: 1 - LED 1 (indicates status of the T1 sensor); 2 - LED 2 (indicates status of the T2 sensor);
3 - LED 3 (warning / closing / opening in the negative logic setting / relay); 4 – Display
4. Mode selection, Parameter setting
The TM-201A thermometer can be used in one of the preset modes (F1 – F5). The selected mode appears on the display
for 3 seconds after connection of the power supply. The F1 operation mode and the values highlighted with bold type
are set as default (in the mode tables see the Default columns).
In the standby condition the TM-201A thermometer shows the temperature measured by the connected sensors
(or “--.-“ if no sensors are connected). If not, briefly disconnect and reconnect the power supply.
At the terminal-board side the thermometer is equipped with two keys that are used to set the operational modes
and parameters. The keys are identified with the Ÿ(UP)and ź(DOWN) symbols. By pressing a key you make a selection
and browse the settings; simultaneous pressing of both the keys is used to enter the setting mode and to confirm
a selection. There is a functional delay during the parameter setting mode; if no key is pressed for a minute, the setting
mode will be terminated, incl. saving all the parameters.
Selecting and setting an operational mode (F1 – F5)
To set an operation mode, follow the points below:
1) Press and hold both the keys ŸDQGź for 6 seconds.
2) A short beep will sound and the current operational mode will start flashing on the display (F1 in the default
setting).
3) Press the
Ÿor źkeys briefly to select the required operational mode (F1 – F5).
4) Confirm the mode by simultaneously pressing the ŸDQGź keys for a short time (for less than 2 seconds).
5) Saving the selected operational mode is indicated by its flashing (for approx. 3 seconds) and a continuous
acoustic signal (for approx. 2 seconds).
6) Now, the first parameter of the selected operational mode is displayed (the P2.1 parameter in the F2 mode,
the P3.1 parameter in the F3 mode etc.) To set the parameters, follow the procedure below.

Example of using the F1 mode
The thermometer only contains one relay; therefore,
only use the relay switching in the F1 mode for monitoring
of the minimum (P1.1) or maximum temperature (P1.2).
The relay will be closed if the temperature drops below
the minimum value or if it exceeds the maximum value.
The closing of the relay can activate remote notification
of the user via an external device. It may also
be accompanied by an acoustic indication (P1.3).
Only one T1 sensor or both the T1 and T2 sensors
can be used (P1.4). If both the sensors are used, the set limit
is monitored by both the sensors (T1 and T2).

End Exiting the setting mode
If an installation requires it, the value of the P4.2 parameter can be higher than that of P4.1.
If both the values (T1 and T2) are achieved, the relay will remain closed (T1 takes priority).
Example of using the F4 mode
The thermometer monitors the priority of the accumulation
tank
- T1 for closing (P4.1) – the tank takes priority
- T2 for opening (P4.2) – the boiler takes priority
The relay is closed when the set temperature is achieved
at the T1 sensor and it is opened on cooling at the T2
sensor.
Auxiliary relay(s) can be used not only to switch a valve
(hydraulic switch), but also to block or switch a gas (electric)
boiler.
The relay logic can be reversed (P4.4) depending of the
type of the valve used (normally closed/open).
4.5. Mode F5 – Differential thermostat
Parameter Description Range Default
P5.1 Closing difference - determines the temperature difference of the T1 –
T2 sensors to close the relay.
1 °C to 30 °C 10 °C
P5.2 Opening difference - determines the temperature difference of the T1 –
T2 sensors to open the relay.
1 °C to 30 °C 3 °C
P5.3 Minimum T1 sensor temperature – determines the temperature at the
T1 sensor at which the relay will be closed if the switching difference
condition of P5.1 is met at the same time.
-20 °C to +105 °C 30 °C
P5.4 Maximum T1 sensor operation temperature – if this temperature is
exceeded, the relay will be opened (protective function).
OFF/
-20 °C to +105 °C
OFF
P5.5 Maximum T2 sensor operation temperature – if this temperature is
exceeded, the relay will be opened (protective function).
OFF/
-20 °C to +105 °C
OFF
P5.6 LED 3 indication – indicates closing (opening in the negative logic) of
the relay.
ON / OFF ON
P5.7 Negative relay logic - reversed logic of the relay function (permanently
closed in the standby condition).
ON / OFF OFF
P5.8 Minimum relay closing time - used to limit too frequent switching on
and off of the connected device. Parameter description, see P1.7.
OFF, 1 to 15 min OFF
P5.9 Minimum pause time - used to limit too frequent switching on and off of
the connected device. Parameter description, see P1.8.
OFF, 1 to 15 min OFF
End Exiting the setting mode
The actual possible range of the differences depends on the settings of the limits. Example: If the closing difference is set
to 15°C, the setting range of the opening difference will be 1 °C – 14 °C.

TM-201A multi-functional electronic thermometer, - 6 - MNU51203
Example of using the F5 mode
The thermometer monitors charging of the hot water
reservoir (e.g. in a circuit with a solid fuel boiler)
The relay will be closed if the T1 temperature
of the heating water is higher than the T2 temperature
in the reservoir by the required number of degrees
(P5.1, switching difference).
The relay will be opened if the difference of the T1 – T2
temperatures decreases to the set value (P5.2, opening
difference), or if the maximum set hot water temperature
in the reservoir (P5.5) is achieved.
Thus, the settings of the closing and opening difference
can be used to control exceeding the heating water
temperature. You can also set the minimum T1 operation
temperature to avoid cooling the boiler during the power
increase stage (P5.3).
5. Warning indication
A missing temperature sensor that is required by the selected function is indicated by flashing of LED 3 and the respective
LED 1 or LED 2. If only one sensor can be connected in a particular mode, it must always be connected to the T1 terminal.
In the F1 mode the warning indication is active on exceeding the limit values. The acoustic indication can be deactivated
with the P1.3 parameter. If in the F1 mode no sensor is connected to the T2 terminals, the P1.4 parameter must be
set to OFF. In the F2 – F5 modes lighting of LED 3 may indicate closing/opening of the relay (if indication of the relay status
is activated by the respective parameter).
