Installing the WiFi Box
Description of the WiFi Box
The WiFi Box communicates with
RiCLOUD thermostat or with the boiler
RF receiver only via radio frequency
(wireless).
OUTPUTS
The WiFi Box contains a relay (see
page 211) which replicates RiCLOUD
thermostat relays linked to it. It is ON
if at least 1 of RiCLOUD relays is ON, and
OFF if all of RiCLOUD relays are OFF .
The WiFi Box can be wired to the boiler
OTBus connection. This transforms
the WiFi Box into a wireless receiver
of an OTBus command. All of the
information available in RiCLOUD via
the OTBus connection is repeated
to the receiver which wires it to the
boiler; it is therefore an example
of complex
communication.
The relay and OTBus outputs are
identified on the WiFi Box by the term
OUTPUTS and are available via a USB
plug.
The position and distinction between
the 2 outputs on the USB plug are
given below.
