Technical data
The terminal and other devices, connected to the BUS line,
that compose the system, must be powered via the LA BUS
terminal, by the following power-supply units:
the VAS100/MH+OH/PF that can power up to 15 modules
plus 1 THplus terminal,
the VAS100.30+OH/PF that can power up to 35 modules
plus 1 THplus terminal,
the VAS101+OH/PF that can power up to 35 modules plus
1 THplus terminal,
the OH/A.01 that can power up to 35 modules plus 1 Thplus
terminal.
SYSTEM ARCHITECTURE
The system is made up of zone thermostats and by actuators, all of which are interconnected via a non-polarized 2-wire BUS
line. It can control up to eight thermal zones.
Each thermal zone must be fitted with one of the following devices:
TA/P1 (temperature sensor with display), THPLUS (terminal with temperature and humidity sensor), OH/SRI (temperature and
humidity sensor), OH/MT2 (module to connect two temperature sensors), OH/Z.02 (zone temperature control module).
Besides a maximum of 8 temperature zones, it is possible to connect, to the BUS line, the OH/SRE temperature humidity and
external pressure sensors, the OH/GSM.01 or the OH/ETH remote access modules, and the input/output expansion modules
for (OH/RI, OH/3RPI, etc...) BPT home automation systems and the OH/MPE6KW energy measuring device.
☞
The system has a limit of 40 modules, for reasons of communication over the BUS line.
