CET 2000B-RF Wireless Electronic Cylinder Thermostat
Brand: Danfoss
The CET 2000B-RF is a battery powered RF cylinder thermostat which measures cylinder temperature using a strap-on cylinder temperature sensor.
The sensor is fitted to the cylinder wall and wires directly to the thermostat, which is normally located adjacent to the cylinder.
The clamp-on sensor comes complete with a spacer piece to enable installation with most thicknesses of cylinder insulation (25-55 mm).
A receiver unit is mounted next to the boiler or zone valve and responds to commands issued by the thermostat over secure wireless connection. This avoids the need for wiring between the thermostat and boiler or zone valve, reducing installation time and cabling.
This arrangement is perfectly suited for new installations where furnishings prohibit running recessed or surface mounted cabling, and in existing installations where the cylinder is being moved or replaced.
