User manual HONEYWELL MARS SERIES TRV DATASHEET

[. . . ] TRV BODY WITH STROKE LIMITATION, EXTERNAL THREADS PRODUCT DATA V305 MARS Series TRV Body Application Thermostatic radiator valve bodies (TRV bodies) are fitted on the supply or return of radiators or heat exchangers. Together with a radiator thermostat, for example the Thera-4, they control the room temperature by regulating the flow of hot water into the radiator.

The TRV body is controlled by the radiator thermostat. Air from the room passing over the sensor of the radiator thermostat causes the sensor to expand when the temperature rises. The sensor acts onto the valve spindle and this causes the TRV body to close. When the temperature falls the sensor contracts and the spring-loaded valve spindle is opened. The TRV opens in proportion to the temperature of the sensor. Only the amount of water required to maintain the room temperature set on the radiator thermostat can flow into the radiator. Please Note: · To avoid stone deposit and corrosion the composition of the medium should conform with VDI-Guideline 2035 · Additives have to be suitable for EPDM sealings · System has to be flushed thoroughly before initial operation with all valves fully open · Any complaints or costs resulting from non-compliance with above rules will not be accepted by Honeywell · Please contact us if you should have any special requirements or needs Setting procedure Turn the pre-setting screw until stop. Mark position of screwdriver slot as reference point. Then turn anticlockwise according to reference figure obtained from the pressure drop chart.
