Parameters measured in each measurement channel together with archive parameters are stored in 

memory  and  can  be  displayed  on  LCD,  printed,  transmitted  through  optical  interface  or  through  bi-
directional galvanic ally-insolated M-Bus, CL or RS-232 interface. 

If current output module is used, 1-st current output parameter will correspond to 1-st pulse output 

parameter (respectively 2-nd current output parameter will correspond to 2-st pulse output parameter). In 
this case output frequency mode should be activated. Minimum value of the selected range of a current 
will correspond to zero (0) value of the output parameter, and maximum value of the selected range of 
current will correspond to the maximum value of the chosen parameter: flow rate

- q

temperature

160 °C, pressure

flow rate 

[m3/h] for this system. 

  User may set current limits (0-20mA or 4-20mA) by using appropriate jumpers. 

 

5. MARKING AND SEALING 

 

5.1.Marking: 

 

There are following information on the front panel of calculator - 

manufacturer’s trade mark , type 

of calculator, serial number,  year of manufacture, EC-type examination certificate number, limits of the 
temperature,  limits  of  the  temperature  differences,  environmental  class  by  LST  EN1434-1, 
electromagnetic  and  mechanical  environmental  class,  enclosure  protection  class,  type  of  temperature 
sensors, conditional designation of measuring scheme for1st and 2nd heating system, flow sensor placing 
(in forward or return pipe), flow inputs pulse values, maximum flow rate, power supply. 
 

Numbers of terminal pins are marked close to the terminal  
5.2.Sealing: 
The following calculator sealing is provided: 
M

anufacturer’s  warranty  seal 

-  adhesive  sticker  on  the  fixing  bolt  of  electronic  module  under 

protecting cover (Fig. 8.2, pos. 1)  

After  verification  m

anufacturer’s security

  seal  -  adhesive  sticker  on  the  bolt  of  cover  protecting 

electronic module (Fig. 8.2, pos.2)  

Installation seals 

  hanged seals on the fixers of junction of the top and bottom part of the housing 

of calculator  (see Appendix D). 

5.3.  Flow,  temperature  and  pressure  sensors  are  marked  and  sealed  according  to  requirements 

provided in relevant technical documentation. 
 

6. SAFETY REQUIREMENTS

 

 

The calculator is made and inspected in compliance with EN61010-1. 
There are no life dangerous factors, when calculation unit is powered from 3,6 V lithium battery. 

If calculation unit is powered from mains power supply, it contains dangerous ~230 V electrical current. 

It is necessary to follow general safety requirements during installation and maintenance process. 

The  electrical  connections  must  be  made  in  compliance  with  the  relevant  standard  while 

observing  local  safety  regulations.  Only  qualified  technical  personnel  may  install  and  maintain  heat 
meters (certificates for electrical installation work with equipment up to 1000 V are required). Personnel 
must be familiar with appropriate technical documentation and general safety instructions. To ensure safe 
operation, the user must observe the notes and warnings contained in this instruction. 
 

Protective grounding is not required, because housing is made from plastics, and conductive parts are 

not exposed to the surface. Device comply with the II safety class.  

To prote

ct power circuits from current overrun, 1A fuse, marked “F1”, is mounted on the bottom 

side of power supply module. Remove power supply module to replace the fuse. 

If  relay  output  current  exceeds  2  A,  it  may  damage  output  circuits.  It  is  recommended  to  use 

additional protection circuits to protect relay outputs from damage. 

Operation  safety  requires  reliable  isolation  of  electrical  circuits,  stable  mounting  of  calculating 

unit and proper grounding of all system components. 

Safety  requirements  for  flow,  temperature  and  pressure  sensors  are  provided  in  appropriate 

technical documentation. 
 

 

Warning!  Switch  off  mains  power  supply  before  changing,  repairing,  connecting  or 

disconnecting system parts! Power switch has to be installed close to the calculator.
