RAS-D radiator thermostats are designed for use in 2-pipe domestic heating systems.
All RAS-D Combi Packs comprises either a RA-FS angled pattern bi-directional valve or a RA-FN straight valve and a RAS-D sensor designed for 2- pipe heating systems. Combi Packs are also available with a RLV-D lockshield valve. For further data on the lockshield valve please see separate RLV-D data sheet.
The RA-FS have a ½” BSP (R½”) tail piece connection to the radiator and are available with 15mm, 10mm or 8mm compression fitting or an elbow with 10mm push-fit fitting to connect the valve to the pipe work.
The RA-FS valve bodies are reversible and bidirectional and include a flow-selectable feature to ensure trouble free installation without any risk of water hammer. For optimum performance, Danfoss recommend the sensor be mounted horizontal where at all possible.
The straight RA-FN have a ½” BSP (R½”) tail piece connection to the radiator and is available with 15mm compression fitting is not bi-directional.
All valves are supplied with a protective cap, which can be used for manual regulation during the construction phase. The cap must not be used as a manual shut of device.
RAS-D sensors are equipped with a snap-lock mechanism, which ensures a quick, firm mounting to the valve without the need of tools. Both built-in and remote sensors are available in the RAS-D range. RAS-D incorporate a “Frost Protection” setting and a “Positive Off” feature for maximum user flexibility. Temperature range is from 8°C to 28°C.

Note: Remote sensors can be used in all applications.
