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.

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 

UP

Ÿ

 and 

DOWN

ź

 control 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.

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
