The heater switches on automatically straight after
reaching the flow rate over 2,5 l/min. The temperature
control system selects an appropriate heating
power depending on the rate of flow, temperature
setting (set with the use of a knob on the front case)
and the temperature of water in the mains.
There are two indicators on the case:
-
green – power supply "on",
-
red – heating "on".
Other modes are shown by flickering green light.
The unit was switched off because the temperature has ex-
ceeded the maximum value (fault signal will not disappear
until the appropriate rate of water flow is reached).
The unit was switched off by a master appliance.
The inlet temperature sensor failure.
