Installation and Attentions
The heat meter both can be installed in Inflow pipe or Return flow pipe (factory default installed in the inflow pipe, if need to install on the return pipe, must be clearly indication before the factory during the production). When installation, should pay attention to the flow direction of medium is as the same as the arrow on the heat meter pipe body.
Special note: no matter the heat meter installed on inflow pipe or return flow pipe, the temperature sensor should be properly connected ( red label for inflow pipe, blue label for return pipe)
