Engineering notes
Selection of the components required is made with the help of the following tables.
Replacement of the WRV81 / WRV84 by a Siemeca™ M-bus heat meter, a motorized
zone valve, a mounting kit and a control and heat meter interface.
200 l/h 400 l/h 750 l/h 1,500 l/h
up to 1,000 l/h above 1,000 l/h

If, up to now, the adjusting screw has not been fully opened, the components for “up to
1,000 l/h“ can also be used for design flow rates above 1,000 l/h. In that case, the ad-
justing screw must be appropriately opened.
Replacement of the WRV83 by a Siemeca™ M-bus heat meter, a mounting kit and a
control and heat meter interface.

If flow limitation is required, “Replacement for WRV81“ must be selected since flow
limitation takes place via the zone valve.
