Designated use
Counting of thermal energy in heating and/or cooling plants (depending on
meter model) with closed heat exchanger circulation system and water as heat
carrier. In addition, instantaneous values (thermal power, flow of heat carrier,
temperatures) can be displayed.
Be sure to read the installation and operating manual before installing /
commissioning completely. This allows you to protect yourself and prevent
damage. Check the contents of the packing before installation to be complete.
This installation and operating manual has to be handed over to the end user.
