5. Communication
The flow sensor has two pulse outputs for connec-
tion to a heat meter.

7. Disposal
The meter (standard version) contains a
lithium battery, which is not rechargea-
ble. Do not use force to open the battery.
It must never come into contact with water,
short-circuited or exposed to temperatures over
75 °C.
Empty batteries and no longer required electronic
devices or components are hazardous waste.
This device must not be disposed together with
the domestic waste.
Return it to the manufacturer for recycling.
