INSTALLATION PROCEDURE
General Requirements
Prior to installing the meter:
• Check the complete set of the meter with that specified in the technical documentation;
• Check for any visible mechanical defects;
• Check the configuration of the meter and change it, if necessary
The meters may only be installed by qualified specialists in accordance with the requirements of this document and the meter
installation design
DO NOT lay signal wires closer than 2 in (5 cm) from power cables or cables of other devices
Checking the Meter Configuration
Prior to installing the meter, verify that its configuration complies with the requirements for the specific facility and change it,
if necessary (if the meter is in the transport mode, the configuration can also be changed by the press-button or with
HEAT3_service configuration software, without damaging the meter structure or seals) The following parameters are verified
(the factory settings for the meter are their standard ones):
• Whether the meter is intended to be installed in a supply or return pipe;
• Whether the meter is intended to measure heat energy or heat and cooling energy;
• Energy measurement units;
• Displayed energy resolution (point position);
• Whether the tariff registers are activated and the functioning conditions of the tariff registers;
• Whether the pulse inputs are activated, their purpose, pulse values, initial values of their volume registers, and volume
register resolution (point position);
• Whether the pulse outputs are activated, their purpose, pulse values, initial values of their volume registers, and volume
register resolution (point position);
• The reporting year and month date;
• The subscriber number;
• The internal clock time;
• M-Bus interface addresses and communication speed
OTEE:
N
The transport mode will turn off automatically (the possibility to change configuration parameters will be turned off)
when the meter starts operation and the volume integrator has accumulated more than 1 litre For meters powered
externally without a battery, the meter will remain in transport mode if the meter is not powered, but there is flow
The transport mode can also be turned off using the button (like turning on
Test Mode
) and with the HEAT3_service
configuration software
Procedure for Checking the Meter Configuration
If the meter is in the transport mode, its display is off in the stand-by state The display is turned on by pressing the button
and, as long as the meter is in the transport mode, it will turn off after 5 minutes (in the normal operation mode, the display is
constantly on and constantly shows the value of measured energy)
To review and change of the configuration, press and hold down the button until INF turns on at the bottom of the LCD To
select a parameter, press and release the button then change the parameter, if necessary
