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.
Designated use
Counting of thermal energy in heating and/or cooling plants (depending on meter
model) with closed heat exchanger circulation system and water (for special
versions of C5-ISF also for water glycol mixtures, not calibrated) as heat carrier. In
addition, instantaneous values (thermal power, flow of heat carrier, temperatures)
can be displayed.
