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.

TM-201A multi-functional electronic thermometer, - 4 - MNU51203

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).

OFF, 1 to 15 min OFF

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).
