KNX Heat Consumption Measuring Device Heat Meter / NZR
APB
Introduction The Arcus-EDS Heat Meter is a „Dialog WZ-CD / -HY“ Heat Consumption Counter (calibration optional) from the company NZR, with an integrated KNX Bus Interface for remote reading and monitoring. The electronic counter is operated by a lithium battery with a 5-year lifespan and 1-year additional reserve. The KNX bus interface is built into the counter and is connected non-reactively with the external terminal block. The meter with the integrated bus interface is authorized by the Physikalisch Technischen Bundesanstalt (PTB) (German Federal Institute of Physics and Metrology).

Parameter: The following settings are available to set the parameters with ETS:
The following is available for all items except Serial Number and Error Number: Periodic Transmission (2min) Transmission - Change No Transmission
The current measurement is transmitted every 2 minutes to the bus. The current measurement is transmitted to the bus only when a change occurs (minimum interval 2 min). The current measurement is not transmitted automatically (Measurements are read manually).
Installation The heat meter must only be installed and put into operation by an authorized specialist. In addition, knowledge of Engineering Tool Software (ETS) is required. Set-up is carried out with ETS Version 2 or higher. You will find the heat meter in ETS under manufacturer: Arcus-eds, Product Family: Meter, Product Type: heat meter. The EIB programming button and programming LED are located on the attached housing. (see above). Technical data for the heat meter can be found in the data sheet of the manufacturer NZR: Technical Documentation Heat Meter Dialog WZ-HY db-wz-cd.pdf / db-wz-hy.pdf (see attached)
Program de-activate and reset sensor: If there is an error in programming and the counter no longer reacts, you can delete the project by pressing the program button. Press the program button down while connecting the EIB bus clamp and wait for the program LED to light up. This takes from 5-10 seconds.
