3.0 Installation
3.1 Parts of the Enclosure
The OpenBAS-HV-RF433R consists of two modules: the RF module and the I2C module. The
RF module receives information wirelessly from the OpenBAS-HV-WLSTH thermostat. The
I2C module is connected to any OpenBAS NX controller, or an OpenBAS-NWK-ETH3
controller through the I2C connection.
The RF module and the I2C module communicate with each other over wires (shown in
section 4.2 on page 16). The maximum wiring distance between the RF module and the I2C
module is 49 feet (15 m).
Each module consists of a circuit board and an enclosure.
Figure 1 Parts of the enclosure
Note: Installation of OpenBAS-HV-RF433R controllers should be in accordance with
the Canadian Electrical Code or the National Electrical Code, and comply with all
local regulations. Final acceptance is subject to the Local Authority Having
Jurisdiction (AHJ).
