The LTX-21 solution is designed to allow connection to a Trend
BMS system. It allows a fully functional solution to be
achieved. The LTX-21 and associated Toshiba LonWorks gateway are
usually mounted in the control panel with the outstation. We
have two possible variations, which are outlined below.
LTX-21 and RBC-LG1 Combination
This uses a LTX-21 and an RBC-LG1-PE, which
connects to a maximum of sixteen indoor units however; the
TCB-PCNT20TLE network adapters are required to convert back to
the AI network. This option will be cost effective for single
split installations with less than 7 indoor units for all other
situations use the solution below.
LTX-21, LTX-VCI and TCB-IFLN640TLE Combination
This solution uses an LTX-VCI and TCB-IFLN640TLE
for the control of a maximum of 64 indoor units. The solution
uses an LTX-21 for every 16 indoor units as these connect to the
Trend outstations. For example, for a total of 64 indoor units
you would use four LTX-21’s.
In each of the above cases, multiples of the
above combinations can be used to accommodate larger systems.
