Danfoss CET2000B-RF Wireless Cylinder Thermostat
Features
The CET 2000B-RF is a battery-powered RF cylinder thermostat that 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 (25-55mm).
A receiver unit is mounted next to the boiler or zone valve and responds to commands issued by the thermostat over a 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.
The CET2000B-RF includes a large easy-to-read LCD display which is backlit for viewing in dimly lit locations.
Hot water temperature adjustment is made by simple up/down buttons and the digital display allows accurate settings. In normal operation, the display will show the cylinder temperature, when the buttons are pressed, the display changes and flashes the set temperature required.
A flame icon is displayed whenever the thermostat is calling for hot water demand and an aerial icon confirms that the thermostat is connected to the receiver.The Thermostat can be placed in standby mode where hot water isn’t required for prolonged periods or where tampering is an issue the set temperature can be locked, both modes indicated by icons on the display.
The display also gives an indication when the batteries need replacing and should there be an issue with the cylinder sensor error codes are shown.
