LonWorks TP/FT-10
Option module for PolluStat

1. Use of the option module

The LonWorks TP/FT-10 option module is used to connect the PolluStat heat meter to LonWorks network
using TP/FT-10 channel.
The module is based on LonWorks 2.0 technology on Echelon FT 5000 Smart Transceiver chip. No credits
charge in OpenLNS CT and LonMaker/LNS Turbo Edition applications during commissioning the modules.
The module is compliant to ISO/IEC 14908-1 (EN14908-1, CEA-709.1) and ISO/IEC 14908-2 (EN14908-2,
CEA-709.3) standard.

2. Safety instructions


The installation, electrical connection and commissioning the module should be made
by qualified specialists only.

The LonWorks option modules may only be used for the PolluStat meter, otherwise
the modules or the heat meter could be damaged.

The included lithium battery and the meter battery must not be recharged,
short-circuited, put in contact with water or exposed to temperatures of more than 80°C.

Batteries and module waste may only be disposed at suitable collection centers
for professional waste disposal.

The communication modules are delivered in the form of circuit board. Is highly
recommended that normal static precautions be taken in handling and assembly of this
module to prevent damage and/or degradation which may be induced by ESD. Failure
to observe proper handling and installation procedures can cause damage. ESD
damage can range from subtle performance degradation to complete device failure.
