Product overview
The CET B-RF is a battery powered cylinder thermostat
which measures cylinder temperature using a strap-on
temperature sensor. The sensor is fi tted to the cylinder
wall and wired to the thermostat, which is normally
located adjacent to the cylinder.
To avoid the need for wiring, the thermostat and boiler
or zone valve communicate to each other using secure
RF wireless communication. A receiver unit is mounted
next to the boiler or control valve and responds to
commands issued by the wireless thermostat.
