8 Tests
8.1 Checking the water heating system
Set water heater to maximum permissible temperature and
prepare hot water
Open hot water pipe and test hot water leakage
Disconnect the pressure sensor - plug on the FlowTimer+ and
thus interrupt the cold water supply
The status display of FlowTimer+ shows red
At the moment of interruption, a run-on from the hot water circuit
must not be detectable
There is a risk of scalding if hot water runs down!
Disconnect the power supply to the FlowTimer+ to
prevent possible shut-off.
A specialist must check the installation.
The system is not operational until clarified!
If the hot water leakage is due to the system, different thermostatic
fittings are commercially available to solve the problem.
